Pinus lanceolata lamb. (1803)
Cunninghamia sinensis R. Br. ex Rich., Mem Conif. 80 (1926)
Widely distributed in the mountain valleys of Central and Souuth China, originally discovered in the Island of Chusan in 1702; Introduced to Kew by William Kerr in 1804. E.H. Wilson found the tree in large forests at altitudes of 800-1300 m in Omei Shan, and it is also plentiful in Ichang and West Szechuan.

Crinum moorei Hook. f.
Botanical Magazine t. 6113. vol. c (1874)
Crinum Moorei was introduced into the Glasnevin Gardens in 1863, by a friend of Dr. Moore's, Mr. Webb, who had served on the commissariat staff of our army in South Africa, and had brought the seeds from the interior -- as Dr. Moore thinks -- of Natal.
L'illustration horticole 9: misc. p.40. 1862.
Nous avons eu pour la première fois conaissance de cette belle et remarquable espèce en visitant (juin 1861) la riche collection de cactées et de plantes grasses de toutes espèces, cultivées chez M. François Cels, Chaussée de Maine (Petit-Mont-Rouge, Paris). En ce moment, 15 avril, elle est encore en fleurs, depuis la fin de dècembre dernier, haute à peine de vingt centimètres, sans la panicule. [...] Nous n'en conaissons ni la patrie, ni l'auteur de sa découverte ou de son introduction ; mais pouvons la recommander en conaissance de cause à tous les amateurs, à ceux même qui n'aimeraient les plantes dites grasses (et pourquoi?); elle est d'une croissance rapide; car l'individu en question, haut de 0,02 centim, au moment où nous l'avons planté à l'état de bouture, a, en six mois à peine, com nous venons de le dire, acquis les dimensions dites plus haut, et est encore en pleine floraison au moment où nous parlons.
C. multicava is a moderate to fast-growing, mat-forming, evergreen groundcover up to ± 300 mm, that produces an outstanding uniform effect when planted in masses. As with all members of the genus, the glossy, oval to round leaves are formed in opposite pairs. They are light to dark green depending on the position in the garden, darker in the shade and paler in semi-shade to sunny places. The flowers are petite, charming little stars hence the common name fairy crassula, and appear in masses above the attractive leaves. The leaves contain hydathodes (water secreting pores), which serve for rapid absorption of water from the leaf surface.
C. multicava occurs on forest margins, river and stream banks, and in coastal and subtropical thickets from Mpumulanga, Natal to the Eastern and s outhern Cape . Plants show a preference for well-composted, deep soils as well as clay soils and occur in partial shade. They are found in sheltered, frost-free areas.
... infusions of the plant are sprinkled around the homestead as a protective charm against lightning.

Notes on New or Rare Plants
Gynerium Argenteum ; (or, Arundo Dioica, or A. Selloana). The Pampas Grass of South America, where it inhabits the vast plains, and is said to grow ten yards high, and bear panicles of silky, silvery-white flowers two feet or more long.
It is a tall perennial plant in our own country and its fine plumes of flowers, borne by such a noble plant, renders it highly interesting and ornamental. It was introduced from South America by Mr. Moore, curator of the Botanic Garden, Dublin. The plant appears to be hardy in this country, flourishing in the garden of Robert Hutton, Esq., of Putney Park, near London. It is also in the Chiswick garden.

Gleanings and Original Memoranda
231. Gynerium Argenteum. Nees, (aliàs Arundo dioica Sprengel; aliàs Arundo Selloana Schultes.) A tall reedy perennial, with harsh serrated leaves, and large erect silky plumes of flowers. Belongs to Grasses. Native of Brazil and Montevideo. (Fig. III.)
This noble plant, now called the Pampas Grass, in consequence of its inhabiting the vast plains of S. America so named, has been introduced within a few years through Mr. Moore, of the Glasnevin Botanic Garden. Although but a Grass it will probably form one of the most useful objects of garden decoration obtained for many years. In stature it rivals the Bamboo, being described as growing in its native plains several times as high as a man. The leaves are hard, wiry, very rough at the edge, not half an inch broad at the widest part, of a dull grey green colour, much paler below. They are edged by sharp points or teeth, little less hard than the teeth of a file. The flowers appear in panicles from one and a half to two and a half feet long, resembling those of the common reed, but of a silvery whiteness, owing to their being covered with very long colourless hairs, and themselves consisting of colourless membranous glumes and pales.
According to Prof. Kunth this species is an Arundo. But to us it appears quite as different from that genus as from Gynerium. And although it is by no means one of the same genus as G. saccharoides, yet it may as well preserve its common name, faulty though it be, as be transferred to Arundo, from which it must be expelled. The inflexed hook of its pales is extremely remarkable, and, together with its dioecious character, leads to the inference that it may be a genus distinct from either.
The plant appears to be hardy. The annexed sketch was made in the garden of Robert Hutton, Esq., of Putney Park ; the species exists also in that of the Horticultural Society, to which it was presented by the Botanic Garden, Glasnevin.
Given the similarity between these two notices it is difficult to know which is an original memorandum and which a "gleaning"!"

A remarkably pretty plant, with thick, evergreen, shining leaves, and large, white odorous flowers. We first received it at the Royal gardens from Berlin, in 1862, and more recently from other quaters. Its native countries are Japan, Bonin, and the korean Islands. Though variable in habit, stature and foliage, it may always be distinguished from its near ally, the Chinese R. Indica, by the much larger flowers and broad obtuse bracts.

Usually described erroneously as D. burgessiae × D. wallichii, Cayeux states quite clearly that the parentage is D. mastersii × D. wallichii.

DOMBEYA CAYEUXII Le climat de Lisbonne se prête, mieux que tout autre, à l acclimatation d'un certain nombre de plantes tropicales. Les Palmiers, par exemple, s'y développent tout aussi bien, pour ne pas dire mieux, que sous le climat de Nice ou Cannes. C'est ainsi que certains Areca et Kentia y mûrissent parfaitement leurs fruits. Grace à la clémence de ciel en ce pays où le thermomètre ne descend jamais au-dessous de zéro, il nous a été donné de faire des essais sur différents genres, qui, croyons nous n'ont jamais prospéré, en plein air dans les jardins européens.
Parmi ceux-ci, un des plus intéressants, tant au point dé vue du feuillage qu'à celui de la beauté des fleurs, est certainement le genre Dombeya.
Originaire de l'Afrique australe, de Madagascar et aussi de l'Inde, le genre Dombeya comprend environ une trentaine d'espèces, depuis qu'on a joint le genre Astrapœa; il appartient à la famille des Bythnériacées. L'espèce la plus anciennement cultivée en Europe est, très probablement, le Dombeya (Astrapœa) Wallichii de Lindley qui, d'après le Botanical Magazine aurait été introduite de Calcutta aux jardins royaux de Kew, par le Dr. Wallich, origine e douteuse, mais il y tout lieu de croire qu'elle habite l'ile de Madagascar. Sa première floraison en Europe aurait eu lieu au Jardin de La Société d'Horticulture, à Chiswick (Angleterre), en juin 1823.
Il ne s'agit donc pas d'une introduction récente, mais plutôt d'une de ces bonnes vieilles plantes si chères à M. Van den Heede, laquelle, sans beaucoup de soins, nous gratifie de ses gros bouquets de fleurs rouges suspendus à l'extrémité des rameaux par de longs pédoncules.
Une autre espèce, connue sous le nom de Dombeya (Astrapea) Mastersii Hook, fut découverte, en abyssinie, vers 1862, par le capitaine Grant et fleurit également, pour la première fois en Europe, aux Jardins royaux de Kew, en 1867. Elle differe surtout du D. wallichii, par sa floraison plus abondante, par ses feuilles d'un vert plus clair et surtout par ses nombreuses fleurs en bouquets, du blanc le plus pur. Elle est parfaitement rustique sous le climat de Lisbonne où elle se couvre de fleurs et fructifie, chaque année, en feverier, sans qu'il soit necessaire de l'arbriter.
Frappé par la beauté et la rusticité du D. mastersii, nous fécondions cette espèce, en 1895, par le D. wallichii que nous possédions également en fleurs dans les serres du Jardin botanique. Des graines semées, naquirent huit plantes, dont la plus forte, confiée à la pleine terre la même an- née, épanouit ses splendides bouquets de fleurs rose tendre, au printemps de 1896. Voici une description qui a été faite de la plante : « Arbrisseau de quelques mètres de hauteur, à tiges ligneuses, cylindriques, hispides dans le jeune age, comme les pétioles et les pédoncules, l'étiolés longs de 0m12 à 0m15 cylindriques, renflés à la base, accompagnés de deux stipules basilaires, triangulaires, aiguës, cuspidées, ondulées; limbe cordiforme aigu, vert foncé, bordé de grosses dents inégales et aiguës ; nervures saillantes réticulées en dessous, Inflorescence pendante, naissant à l'aisselle de feuilles supérieures. Pédoncule commun robuste, droit ou légèrement courbé, vert, hispide au sommet de même que les bractées involucrales étalées, qui sont vertes, puis rousses, peu nombreuses, lancéolées aiguës, concaves, longues de 0m.015 à 0m,020 sur 0m,005 à 0m,008 de large Inflorescence en corymbe simple, formé de trente à trente-cinq fleurs à pédicelles grêles, longs de 0m.020 à 0m,022, un peu courbés, vert très pâle comme les bractées et les sépales subégaux, longs de 0m.012 à 0m ,014 ; étroitement lancéolés aigus, velus, hérissés, argentés. Corolle en coupe ouverte, d'un beau rose tendre plus paie au centre, large de 0m.030 a 0m ,032 à pétales obliquement obcordés, non équitants, finement veinés, de l'aspect et de la consistance des pétales du Pêcher. »
L'hybride est parfaitement intermédiaire entre les deux parents, tout en ayant conservé la rusticité et la floribondité la plante-mère.
La fig. 8 représente notre plante livrée à la pleine terre en 1895. Elle atteint aujourd'hui environ 3 m ,50 de hauteur sur 2 m ,50 de large et forme une masse de verdure du plus bel effet; Elle est en outre chargée de 270 inflorescences qui ne tarderont pas à épanouir leurs nombreuses fleurs d un très joli rose tendre. L'abondance d'inflorescences est telle e nous avons pu en compter jusqu à douze sur une même ramification.
Le Dombeya Cayeuxii rustique à Lisbonne, ou le thermomètre a accusé une temperature minima de +1º,8 dans l'air et --- 4º,6 rez de terre, pendant l'hiver de 1896, le sera peut-être égalment sous le climat de Nice et de cannes, si on a le soin de le planter à bonne exposition bien abritée.
Dans tous les cas, il se recommande comme plante à très grand feuillage, à isoler sur les pelouses, à instar des Solanum, Nicotiana, Wigandia, etc. Cultivé en bonne terre fraiche, bien fumée, en serre tempérée ou planté en plein terre dans un jardin d'hiver, il récompense le cultivateur de ses soins par sa splendide floraison pendant l'hiver.
En sa qualité d'hybride, le D. Cayeuxii ne produit pas des graines ; mais on le multiplera avec facilité des boutoures demi ligneuses qui s'enracineront assez rapidement dans la bâche à multiplication.

Cordyline indivisa Steud.
Curtis’s Botanical Magazine, No.9096, Volume 151, 1926.
The botanists view:
Cordyline australis (G. Forst.) Endl.
SYNONYM(S) : Dracaena australis G. Forst.
That is straight forward enough. But what about:
Cordyline indivisa (G. Forst.) Steud.
SYNONYM(S) : Dracaena indivisa G. Forst., Terminalis indivisa (G. Forst.) Kuntze
The name Dracaena indivisa hort. was used almost exclusively in the nineteenth century (and even today) for Cordyline australis. This is from a website selling seeds of the true Cordyline indivisa :
Do not confuse this plant with the common Dracaena indivisa a.k.a. Cordyline australis of the plant trade. While the C. australis is commonly grown in mild temperate areas all over the world, the true C. indivisa is a rare and beautiful high altitude species from New Zealand. It is a tall and majestic plant with long leaves that can reach a width of more than 10 cm (4 in.), and in young plants are tinted yellow and orange. C. indivia prefers a moist, cool, even climate such as that of the Atlantic Coast in Europe or the Pacific Coast in the US and Canada.
It is unlikely that Cordyline indivisa was ever grown successfully at Monserrate despite the frequent references to Dracaena indivisa for example in 1885 & 1923.
However just in case here is the description:
Cordyline indivisa (G. Forst.) Steud.
Family: Laxmanniaceae. Also placed in: Agavaceae Asteliaceae Lomandraceae [GRIN Taxonomy for Plants] and of course old fashioned Liliaceae.
That's not very helpful, but reflects current flux and differences of opinion. The European Garden Flora places Cordyline in AGAVACEAE with the following comment: "A very troublesome family from the point of view of identification. Its separation from Liliaceae and the Amaryllidaceae is based, at least in part, on cytological, chemical and anatomical characters, and this makes a clear diagnosis of the family dificult to prepare." That was from my 1986 first edition and is by now itself quite old-fashioned. The family Laxmanniaceae is still not widely recognised, though New Zealand Botanists seem very keen, but then all the genera that are included within it are from the Pacific regions.
Asparagaceae seems to be the momentary consensus - Laxmanniaceae is admitted by APG II (Angiosperm Phylogeny Group; 2003) as an optional segregate from the family Asparagaceae.

Genus Acokanthera, Don; (Benth. Et Hook. F. Gen. Plant, vol. ii p. 696)
Toxicophlaea spectabilis, Sonder in Linnaea, vol. xxiii. P. 79;
The genus Acokanthera was founded by G. Don in the ‘Gardener’s Dictionary’ (vol. iv. P. 485) on Thunberg’s Cestrum veneatum (and other South African plants having no relation thereto), a native of Western South Africa. Subsequently, Harvey, overlooking Don’s genus, established Toxicophlaea on the same Cestrum venenatum, and his name is taken up by A. De Candolle in the Prodomus, and has consequently been current for that plant ever since ; subsequently, a congener was found in Abyssinia, the Carissa Schimperi, A.D.C. (C. Mepte Hochst., and Strychnos abyssinica, Hochst.), and finally the present plant was sent from South East Africa, and published as Toxicophlaea spectabilis by Sonder. The three known species are probably all of them very poisonous. A. veneata (Toxicophaea Thunbergii), Harvey, is the “Gift-boom,” or poison-tree of the Dutch and English colonists. According to Thunberg, a decoction of the bark reduced to a jelly was used by the Aborigines for poisoning their arrows ; and of the A. spectabilis, Mrs Barber writes that the seeds are intensely bitter, and the whole plant considered by the natives to be a deadly poisonous one. The genus is, as Mr. Dyer has remarked (Gard. Chron. l.c.), too closely allied to Carissa, differing chiefly, if not solely, in the want of thorns.
A. spectabilis is a native of the Western districts of South Africa, from Port Albany to Port Natal, where it forms a large shrub, with masses of white very fragrant flowers, on woody sand-hills near the sea. It was introduced by Mr. B S. Williams, and exhibited by him in 1872. Our specimen flowered at Kew in February of the present year.
DESCR. A large shrub, quite glabrous, except the inflorescence, which is slightly hairy or almost glabrous ; branches stout, green, obscurly angled. Leaves three to five inches long, narrowed into a very short thick petiole, coriaceous, elliptic- or oblong-lanceolate, acute, acuminate, or apiculate, shining above with very obscure spreading nerves, paler and opaque beneath. Flowers in dense fasiculated axillary branched short cymes, sometimes forming a globose head towards the top of the branch, pure white, very sweet scented ; peduncles and pedicels very short ; bracts minute, broadly ovate. Calyx-lobes ovate-lanceolate, green, subacute, hairy. Corolla-tube three quarters of an inch long, slender, slightly enlarged upwards, sparsly hairy in the throat ; lobes spreading, ovate-oblong, acute. Stamens included, inserted near the mouth of the corolla, filaments very short ; anthers braodly ovate, with a pubescent terminal claw. Stigma conical, hairy, emarginate. Ovules attached towards the base of the septum. --- J. D. H.

Imantophyllum aitonii Hook.
Bot. Mag. 55: t. 2856. 1828
By perhaps not such an extraordinary coincidence two rival botanical magazines published different names for the same plant ON THE SAME DAY. Hooker's name Imantophyllum was for a long time preferred over Lindley's Clivia, which however eventually prevailed and gained precedence. Even so it was as Imantophyllum that these plants were first grown at Monserrate.
Hooker later wrote the following in a footnote:
It was unfortunate that that plate of I. Aitoni appeared on the same day on which the same plant was figured by Dr. Lindley in the ' Botanical Register' as Clivia nobilis. The name may, we think, thus with propriety be transferred to the present genus, a near ally of, but certainly distinct from, Clivia, Lindl.
This was in relation to Imantophyllum miniata, written in 1854, 26 years after the day on which both names had been published. Quite a grudge! Unfortunately for Hooker this new plant, was also later consigned to Lindley's genus and became Clivia miniata, the most widely grown and beautiful of these plants.
Clivia nobilis Lindley
Botanical Register; consisting of coloured . . . 14: t. 1182. 1828.
This noble plant is supposed to have been one of the discoveries of Mr. Bowie at the Cape of Good Hope, from some of the inner districts of which colony it was probably procured. The plant from which our drawing was made, flowered for the second time in July last, in the princely Garden of his Grace the Duke of Northumberland, at Syon House, and was communicated to us by Mr. Forrest, to whom we are indebted for several observations upon its habit and characters.
At first sight it has so much the appearance of a Cyrtanthus that it may easily be mistaken for one, especially if the detached flowers only are seen. But upon a more minute examination, it will be found that it is not only not referable to that genus, but that it is actually doubtful whether it does not belong to a distinct natural order. In the 'first' place, it does not form a bulb, an almost indispensable character of Amaryllideae, from which there is but one other variation hitherto known, namely in Doryanthes. In the second place, the fruit is not a dehiscent dry capsule, but fleshy and indehiscent; and, thirdly, the seeds are not numerous, compressed, and membranous, but solitary, round, and fleshy. It is, therefore, obviously distinct from Cyrtanthus; and there is no other Amaryllideous genus to compare with it, except Eustephia, the fruit of which is still unknown, but which is peculiarly characterised by its 3-toothed filaments, and which is probably not far removed from Phycella. Perhaps the real affinity of this plant cannot at present be determined: to us it appears most closely allied to Haemanthus, the bulbs of which are very imperfect.
A greenhouse plant, not appearing to require particular care in its cultivation, and propagating either by seeds or suckers.
Roots fleshy, fascicled. Leaves distichous, coriaceous, dark green, strap-shaped, sheathing at the base, retuse and oblique at the apex, rough at the margin. Scape erect, plano-convex, bordered, furrowed towards the summit. Flowers from 48 to 50, on long stalks, pendulous, arranged in an umbel. Perianth tubular, clavate, deciduous; the segments yellowish scarlet, greenish at the apex, obtuse, imbricated in a double row, cohering towards the base, the outer rather shorter than the inner, like those of a Lachenalia. Stamens 6, inserted in the orifice of the tube, equal; filaments smooth; anthers small, oval, greenish yellow, versatile. Ovarium inferior, greenish yellow, 3-celled, many seeded, round, ventricose. Ovula numerous, inserted towards the base of the axis; style filiform; stigma somewhat 3-lobed. Fruit berried, indehiscent, red, generally, in consequence of the abortion of two cells and. most of the ovula, one-seeded, marked at the top by the scar of the fallen perianth. Seed single, ascending, (only seen unripe), very smooth, transparent, oval; hilum small, above the base; foramen in the base; raphe short, raised. Testa , when young, marked with very minute areolations; albumen abundant.
* We have named this genus in compliment to her Grace the Duchess of Northumberland, to whom we are greatly indebted for an opportunity of publishing it. Such a compliment has long been due to the noble family of Clive; and we are proud in having the honour of being the first to pay it.
DESCRIPTION: The leaves are very deeply lobed and are about 200mm long by approximately 150mm wide. Individual lobes are very fine being 1.5-4m wide. Occasionally the lobes are sub-divided into two. The upper surface is shiny green whilst the underside is covered with silvery hairs. The leaf edges are rolled under. The flowers encircle the stem and are produced terminally. The rachis or stem on which the flowers are borne extends a short distance beyond the last floret as in G. sessilis. The bright yellow flower heads, which are produced in profusion over a long period, are about 120mm long by about 80mm wide. The very woolly perianth tube is about 8mm long. The styles, which are the colourful parts of the inflorescence, are about 30cm long.
DIAGNOSIS: This cultivar is different from its parents in that the foliage is intermediate with perhaps a greater affinity to G. pteridifolia. The habit also tends to be intermediate. The flower colour differs in that it is lighter than is usually seen in G. pteridifolia and a much richer colour than is usual for G. sessilis. The flowers encircle the rachis as in G. sessilis but not in G. pteridifolia.

Descr. " After removing the flower-stem, the plant was taken out of the pot, and the earth thoroughly washed from it, so as to allow a complete investigation of its root. This was done with a view of relieving the plant from the encumbrance of a ball of exhausted hard earth. The vertical root-stock is about four inches long, cylindrical, and truncated ; the lower two inches are bare and like a section of a broomstick, about an inch in diameter. From the upper two inches protrude numerous whitish branched fibres, about the thickness of a goose's quill, clothed with a short pubescence on their younger portions. The leaves on our oldest plant were twenty-three in number, in opposite rows, the widened base of each leaf embracing that of the opposite one ; and in this respect, as well as in the root, resembling Clivia. The leaves of our plant are not linear nor rigid, like Clivia, but are linear-lanceolate and stout, and exhibit not only the longitudinal nerves, but some of the stronger transverse partitions ; like those of Clivia, they are perennial. In strong plants they come up from the centre in series of four to five at once, quickly succeeding each other; and about the time that the first of the new series is matured, the flower-stem is pro- truded between the outer one of these and the last of the next older series. The new leaves are of a rather brighter green than the old ones. The flower-stem is flattened, about a foot long, and supports an umbel of twelve to fifteen pedunculate flowers, at first enveloped in a sheath, composed of membranous and membranous-margined bracts. The stamen and style, when the flowers begin to open, are decidedly declining ; but the expansion of the flowers carries the upper stamens a little out of this position, and spreads the whole of them. So far as we have seen, but one ovule in each cell swells. Once, one in each of two cells was matured, and the third was abortive. In two other instances only one in one cell matured, and those of the other cells were abortive. I did not examine minutely the original number of rudimentary ovules. The seeds, being valuable to us, were not cut, so as to examine their internal structure ; but their size was that of a smallish horse-bean, and, though less rugged than those of Crinum, decidedly ' bulbiform at least so both William Wood and myself considered them. They were sown immediately, under the idea that they would not keep, and they quickly pushed up each a leaf. The capsule turned of a brownish colour and became soft, and the integument of the seed was moist ; and on a portion of the exterior being accidentally rubbed off, a silvery membranous coat, like that of the bulb-seeds of Crinum, was exhibited. Our old plant has for the last two years produced fresh leaves and a flower-stem about every four months. It has sent off several suckers from the portion of the root-stock which produces the fibres (if so the thick roots I have described may be called). If the flower-stem be kept in water, possibly some of the capsules may swell a little, so as to exhibit the number of the rudimentary ovules. The corollas are deciduous, as in Clivia, to which I certainly think the plant nearer than to Vallota. The flowers expand about two at a time daily, or in two days or longer periods, but remain so long as to form, along with the others also expanded, a fine head for from two weeks to a mouth, according to temperature.
