The original description by Planchon is not readily available, and is given here for convenience of reference. The introductory matter on p. 265 is necessary for an understanding of Planchon's remarks.

[P. 265.] Flores monoici. — Masc. Periantho 4-partitum, laciniis concavis, æstivatione biseriatim valde imbricatis. Stamina Sponiæ. Fœmin. Perianth, 4-partiti laciniis ovato-lanceolatis, erectis, basi imbricatis. Ovarium oblongum, pilis cinereis brevibus strigosum. Styli 2, ovario longiores, cylindracei, papillis piliformibus brevibus stigmatosi. Fructus......

Frutex v. arbor? Philippinicus, vegetatione Sponiæ. Folia trinervia, serrata, leviter aspera. Cymulae masculæ paucifloræ, abbreviatæ glomeruliformes, longiuscule pedicellatæ, plures in racemum contractuni, brevissinium congestw, racemis axillas folioruni adultoruni occupantibus. Flores fœinei fere omnes in axillis foliorum novellorum sessiles, v. brevissime pedunculati, uno v. altero passim cymulæ masculæ supremæ intermixto.

Botanical Name.

— Aphananthe, Greek aphanes, unseen or invisible, anthos, a flower, in reference to the inconspicuous flowers; philippinensis — this plant was first described from the island of Luzon, in the Philippines.

Vernacular Names.

— Most usually called Elm — it certainly resembles that tree in foliage, and to some extent in habit — but also "Rough-leaved Hickory."

Aboriginal Names.

— "Mail" and "Monduar Gourabie" are aboriginal names quoted by Mr. Charles Moore as formerly current in the Clarence and Richmond River Districts. Mr. Bailey quotes Mr. E. Cowley for the name "Mallban" in use on the Barron River, Queensland.

Dr. Elmer D. Merrill gives the name "Cha" (Tagalog dialect) for an Aphananthe in the Philippine Islands, presumably the present species.

Synonyms.

— Taxotrophis rectinervis, F. Muell. Fragm. vi, 192; Sponia ilicifolia, S. Kurz, in Flora, 1872, 448.

Epicarpurus orientalis is the name given in the catalogue to specimen No. 33 of C. Moore's Northern Woods (London Exhibition, 1862), which (B.Fl. vi, 160) is attributed by Bentham to Aphananthe philippinensis. The names are not really synonyms, and the explanation of the use of the Epicarpurus is doubtless explained by the third paragraph of p. 193 of Vol. vi of Mueller's Fragmenta.

Leaves.

— Note their very rough sand-papery texture.

Timber.

— lt is used at Taree, on the Manning River, for axe-handles, etc.

Timber said to be durable, very hard, not used. — (C. Moore, Cat. N.S.W. Timbers, Lond. Exh., 1862.)

Little is known about this timber, hence the somewhat conflicting statements concerning it.

In the Cat. Queensland Timbers, London Exh. of 1862, this wood (referred to as Celtis sp.) was stated by Mr. Hill to be "in bad repute for durability." It is used for linings, ceilings, etc. It may be found a useful wood for turners. It is close-grained, light in colour, and Mr. Bailey suggests that it might do for stamps.

Size.

— Varying in size from 50 to 70 feet (C. Moore). We have a tree in the Botanic Gardens, Sydney, about 45 feet high with a stem diameter of 4 feet at 1 foot from the ground. At 2 feet from the ground it branches, one stem being 1 foot and the other 2 feet in diameter.

Habitat.

— The following localities are given in the Flora Australiensis:—

NEW SOUTH WALES.

Clarence River (Wilcox, Beekler); Clarence and Richmond brushes, Northern Woods, London Exhibition, 1862, C. Moore, No. 33.

QUEENSLAND.

Brisbane River, Moretori Bay (F. Mueller); Queensland Woods, London Exhibition, 1862, W. Hill, No. 86; Rockhampton, (O'Shanesy); Rockhampton Bay (Dallachy).

It is a tree of the coastal brushes of New South Wales and Queensland. I have it from as far south as the Manning River; its extreme northern limit (in Queensland) requires to be ascertained.

THE NATIVE ELM.

Habitat. — See vol. ii, p. 73.

Mr. R. H. Cambage informs me that he has collected this species at Stroud, which remains its most southern recorded locality so far.
