Myoporum parvifolium R.Br.





Myoporum Parvifolium.
Small-leaved Myoporum.
Class and Order. Didynamia Angiospermia.

Generic Character.

Cal. 5-partitus. Cor. tubo brevi ; limbo 5-fido, subaequali. Stigma obtusum. Drupa baccata, 2 — 4-locularis. Sem. i — 2, pendula.

Specific Character and Synonyms.

MYOPORUM parvifolium ; foliis alternis clavato-linearibus ramulisque glanduloso-tuberculatis, pedunculis subbipartitis, folium subaequantibus.

MYOPORUM parvifolium; foliis alternis linearibus obtusiusculis apice nunc dentatis basi attenuatis ramulisque glandulosis, pedunculis paslim bipartilis dimidio folio longioribus, caule diffufo. Brown Prod. PL Nov. Holl. p. 516. Hort. Kew. ed. alt. 4. p. 60.

POGONIA tuberculata, aspera vel scabra Hortulanis.

This is a very pretty little shrub, with sweetist honey-scented flowers; and flowering almost the whole of the year, is a valuable ornament to our greenhouses.

Being propagated by cuttings without difficulty, it is become pretty common, though no figure of it has, we believe, been hitherto published. We have received specimens of this plant from several quarters, under the names of Pogonia tuberculata, aspera, and scabra. Our drawing was taken from a plant communicated by Messrs. Loddiges and Sons. Introduced in 1803, by Mr. Peter Good.

Hardy Species of Eucalyptus, 1889

Bulletin of Miscellaneous Information (Royal Gardens, Kew), Vol. 1889, No. 27 (1889), pp. 61-62

It is well known that some species of Eucalyptus are hardy in certain districts in this country, but the ordinary Blue Gum, E. Globulus is only sparingly so. We have recently received from Mr. Abbott, Superintendent of the Botanic Gardens at Hobart Town, Tasmania, a small quantity of seed of this species collected from trees growing at high altitudes and exposed to severe frosts. Seeds were also recived of E. coccifera from trees which were coated with icicles a foot long." It is probable that plants raised from seed of such hardy forms would likely bear with impunity the rigours of an English winter. The seed received has all been sown and the results will be duly noted later. In the meantime the following extract from a letter received from Mr. Abbott will be read with interest : -

In the same package I put a little seed of Eucalyptus Globulus from Tullochgorum, a part of the Colony where the winters are severe, and on that account the plants raised from the seed forwarded are likely to withstand an amount of cold that would kill the ordinary form, at all events it is so here, as all attempts to introduce the plants into the district from the southern parts of the island failed, the cold proving too severe. Eventually a few isolated plants of E. Globulus were found growing in a sheltered gully some 20 miles from Tullochgorum. These were the only plants of the species that have been found growing naturally in so cold a climate, and plants raised from these trees were planted about Tullochgorum, and grew into large trees ..."

Baeckea virgata


(2127)
BAECKEA VIRGATA. TWIGGY BAECKEA

Class and Order.
Pentandria (Octandria. Smith.) Monogynia:

Generic Character.

Cal. infundibuliformis, 5-dentatus. Cor. 5-petala, Caps. 3—s. 4-locularis, polysperma, calyce tecta.

Specific Character and Synonyms.
Baekea virgata ; foliis lineari-lanceolatis pellucido-punctatis, pedunculis axillaribus umbelliferis. Bot. Repos. 598.
Baeckea virgata. Hort. Kew. Epit.
Leptospermum virgatum ; foliis oppositis lineari-lanceolatis. Forst. Gen. p. 48. Sweet Hort. suburban, p. 81.

Descr. Leaves opposite, crowded, linear-lanceolate ; faintly
three-nerved, dotted with pellucid glands. Peduncles axillary.
bearing a few-flowered umbel. Calyx superior, 5-toothed,
teeth distant, coloured. Cor. 5-petalled : petals roundish,
with a long narrow claw. Stamens from five to ten, shorter
than the claw of the petal, inserted at the base of the calycine
teeth. Five or ten appears to us the natural number,
but in the flowers we examined, the number was generally
five ; sometimes six, being two stamens to one of the calycine
teeth, and only one to the other four. Our specimen flowered
in the middle of December ; perhaps in a warmer season
there would have been two stamens to each of the teeth.
Filaments short, incurved, terminated with a gland, which
gives to the anthers the appearance of being 3-lobed ; but as
the gland soon dries up, to observe this the examination must
be made before the flower is expanded. The Germen is at
first concave at the crown, but afterward» becomes flat and
enlarged.
ВAEСKЕА, LEPTOSPERMUM, and FABRICIA, are very nearly allied, and all belong to the natural order of Myrti Indeed, except in the number of stamens, which seems also to be inconstant, we do not find any difference between this species and Leptospermum. With the Chinese species we have had no opportunity of comparing it. In our account of Fabricia laevigata, (vide No. 1304) by an error of the press, the Class is said to be Hexandria instead of Icosandria.
Native of New South Wales. Requires only to be protected from frost. Flowers from September to the end of December. Communicated by Mr. Lee, of the Hammersmith, Nursery.

Harmogia virgata ( J.R.Forst. & G.Forst. ) Schauer

A plant was grown under this name at Monserrate in 1861. It was sent there by Sir William J. Hooker at Kew who in one of his many writings on Australian Plants : Hooker's journal of botany and Kew garden miscellany, Volume 8, p. 67, equates this species with Camphyromyrtus pluriflor F. Muell.; "leaves spreading, lanceolate-linear or oblong-lanceolate, acutish, awnless, with flat, perfectly entire margin; peduncles generally three-flowered. HABITAT On the banks of the Tambo, on the Snowy River, and on several of its tributaries."

So the plant was collected in south-eastern Australia. This is significant in determining the true identity of the plant once grown in Monserrate. Modern nomenclature for Harmogia virgata is generally given as Baeckea virgata which under revision in the 1990's by Tony Bean of the Queensland Herbarium was changed to Babingtonia virgata. This species according to this author is however restricted to New Caledonia. Australian plants previously known as Baeckea virgata were assigned to one of 8 species:

Babingtonia angusta
Babingtonia bidwillii
Babingtonia brachypoda
Babingtonia collina
Babingtonia crassa
Babingtonia papillosa
Babingtonia pluriflora
Babingtonia similis


The Monserrate Harmogia virgata belongs therefore to one of the above!

See the ANPSA Blog Gumnuts for more detail and source.

So which of the Babingtonias comes from the banks of the Tambo?

Going back to Mueller:

Baeckea - SECTION IV HARMOGIA

22. B. virgata, Andr. Bot. Rep. t. 598. Usually tall erect and loosely branched, attaining 10 to 12 ft., rarely low and diffuse. Leaves from linear-lanceolate to narrow-oblong, flat and often 1- or 3-nerved, usually acute and half to 1 in. long, but in some specimens all under half in. long, and occasionally some or nearly all obtuse both in the short- and long-leaved forms. Flowers small in the upper axils, usually several together in a loose umbel, on a common peduncle of 2 to 4 lines, the pedicels varying from 1 to 3 lines. Calyx-tube turbinate, at length hemispherical, about 1and a half lines diameter; lobes short and broad, the midrib more or less produced into a conical point or protuberance. Petals about 1 and a half lines diameter. Stamens 5 to 15, none opposite the centre of the petals ; filaments filiform ; anthers didymous, the cells globular, furrowed, opening in short slits; connective thickened into a gland almost as long as the cells. Ovary 3-celled, with 15 to 20 ovules in each cell round a peltate placenta. Capsule nearly flat-topped. Seeds usually angular. Embryo with the slender inflected end very short, with 2 small ovate cotyledons.—DC. Prod. iii. 229 ; Bot. Mag. t. 2127 ; Lodd. Bot. Cab. t. 341; Colla, Hort. Ripul. t. 6; F. Muell.

Bean lists only one species as located at Tambo, Victoria, perhaps this Baeckea utilis is the Monserrate plant?

Eugenia latifolia

Still ruminating over Eugenia latifolia. Previous posting had rejected legitimate identity as Eugenia latifolia Aubl., Hist. Pl. Guiane 1: 502 (1775). on the grounds that this Guinean plant was not in cultivation in Europe in 1885. Proposed as a possible contender was Syzygium malaccense (L.) Merr. & L.M. Perry .

However the 1885 description describes the "Eugenia latifolia" as widespreading and "with six large arms and with roots protruding from the branches somewhat like a Banyan". The inclination here is to say that the Journalist confused his notes with the adjacent Metrosiderus robusta (mentioned in the same sentence). But what if he didn't?

Are there any Eugenias with aerial roots? Along with Metrosiderus what other Myrtaceae have aerial roots and wide spreading branches?

More on Angophora floribunda


http://www.metrotrees.com.au/

Wanted to check up on those aerial roots. Now I see that the foliage is quite different that which Hooker presents in the Bot. Mag. Wouldn't be the first time he illustrated the wrong tree or mixup several species on one plate.

http://www.anbg.gov.au/cpbr/cd-keys/euclid3/euclidsample/html/Angophora_floribunda.htm
Fruit pedicellate (pedicels 0.3–1.4 cm long), barrel-shaped to cup-shaped, (0.6)0.7–1.2 cm long, 0.7–1.1 cm wide, longitudinally ribbed, disc descending, valves 3 or 4, enclosed.

Chittenden RHS Dict. says that Angophora intermedia is grown in many Cornish gardens, often as Metrosideros floribunda.

So we have a problem with homonyms here.

Hooker's plant must be: Acmena floribunda = ? Syzygium floribundum K. Schum. & Lauterb.

So it is a lilly pilly after all.

Back to my earlier posting about Lillypilly.
Australian Plant Census does not accept Acmena genus
Acmena DC. = Syzygium Gaertn.

All in all I'd say Walter Oate's plant was a Syzygium - that is still there - growing next to the Metrosiderus (that has abundant aerial roots).

We all make mistakes. Certainly had me confused for a while.

However beautiful and striking this plant (native of New South Wales) may be, loaded, too, as our tree, above twenty feet high, is, with its charming clusters of bright purple berries, its flowers are quite unattractive, and perhaps amongst the smallest and inconspicuous of all the Myrtle tribe. These flowers appear, like those of many other Australian trees and shrubs, in the winter season, and the berries succeed them in the early spring, causing the extremities of the slender branches to bend down by their weight. The tree is too large, however, for successful cultivation in an ordinary greenhouse, but well suited to our winter garden. De Candolle, I think with justice, refers Sir James Smith's Eugenia elliptica to this species, considering it a variety with white berries and broader foliage, depending on the paler or almost white colour of the berries. This Eugenia elliptica is figured by Sims in the ' Botanical Magazine l. c. ; but the figure does not do justice to the species, and is destitute of flowers, while, on the other hand, the fruit was unknown to Ventenat, who has well represented a flowering specimen.

Descr. A tree in our conservatory, attaining a height of twenty feet, and very much resembling a gigantic large-leaved Myrtle (Myrtus communis). Leaves very dark-green, two to three inches long, ovato-lanceolate, acuminate, pellucido-punctate, short-petioled. Panicles terminal, thyrsoid. Flowers very small. Calyx turbinate or subsemiglobose, with five very indistinct teeth. Petals quite minute, elliptical-cuneate, erect, much shorter than the numerous stamens. Ovary incorporated with the fleshy base of the calyx, which eventually becomes a globose, rich-purple subpellucid berry, the size of a large pea, umbilicated at the summit, of an acid flavour, but destitute of aroma.

Fig. 1. Flower. 2. The same, cut through vertically, showing the stamens and style. 3. Ovary, cut through transversely :— magnified
Described by Oates as growing at Monserrate in 1923: "Metrosideros floribunda (with masses of long adventitous roots hanging from the branches)". Aerial roots? - sounds more like Metrosiderus robusta. But there is a large "lilly pilly" growing at this spot (part of the area called Australia, next to some Podocarpus) maybe this needs a closer look - if it ever flowers in such deep shade.
