The genus Dammara, extending as far south as the northern island of New Zealand, and as far north 
as Borneo and Java, has its focus of geographical distribution in the Polynesian Islands. The genus will 
probably receive considerable additions when the various islands are thoroughly explored, as all the species 
seem to be very local. Eight species are known to me, seven of which I have seen growing in the Botanic 
Gardens of Sydney, New South Wales; and authentic living as well as dried specimens of them I brought 
home and made over to Kew Gardens. I pointed out these specimens to M. Parlatore, when he was in Eng- 
land, to work out the Conifere for De Candolle's * Prodromus, and gave him all the notes and the references 
I had made on the various species. However much some of the species may resemble others in leaf, and 
undistinguishable as they may be in a dry state, nobody who has seen the various species growing side by 
side in the Sydney Gardens can for a moment confound them. Indeed, the different islanders who happen - 
to visit Sydney have more than once pointed out which is the Dammara peculiar to their respective coun- 
tries, as has already been stated by Dr. George Bennett, in his * Gatherings of a Naturalist.’ Every species 
has a peculiar mode of growth, and differently-coloured branchlets and leaves; and those who may be 
inclined to unite most of the proposed species, ought to examine the matter well and wait for better mate- 
rials than are now accessible before they do so. ‘he following are the species known to me, and some of 
the notes made on them at Sydney :— : 
1. D. robusta, Charles Moore, mss. in G. Bennett's ‘ Gatherings,’ p. 953— D. Brownii, Hort. Angl. 
‘Tendara ” v. ** Tedarandara;" Autochthon. Nov. Holland.—Southern Queensland, where discovered in. 
January, 1849, by J. S. Bidwill (Cf. * Kew Journal, 1849, p. 284). Tt is stated by the discoverer to have 
a trunk 150-170 feet high by 3 feet in diameter; a bark smooth, shining, and dropping off in seales; and 
wood, which, when fresh, is tough and yellowish. Judging from the plant in the Sydney Garden, which in | 
1861 was 40 feet high, I think the name “robusta ” well chosen; no other species of the genus has so 
robust a habit. The bark of the branches one year old was green, slightly tinged with brown; whilst the 
nascent branchlets and leaves were pruinose, the pruinose covering disappearing on being touched with the 
finger, and being more intense on the under side of the leaf than on the upper. The foliage generally was 
much more dense than that of either D. ovata, australis, orientalis, or obtusa. 
2. D. orientalis, Lamb. Pin. Ed. vol.i. p. 61. t.38 et 39; Endl. Conifer. p. 189.—* Dammara," Malay.— 
Moluccas, Java, and Borneo. In the Sydney Gardens the specimen had the bark of the branches one year 
old light-brown, and that of the nascent branchlets of the same colour and without any pruinose covering ; 
leaves, just when unfolding, brown on the upper, pruinose on the lower side, but afterwards gradually losing 
the pruinose covering altogether. 
3. D. australis, Lamb. Pin. Ed. vol. ii. p. 14. t. 6; Endl. Conif. p, 190.—* Kauri” v. * Kouri,” Nov. 
Zel.—Northern island of New Zealand. In Sydney Gardens the nascent branchlets were deep purple and 
slightly pruinose, but the young leaves not pruinose- M S 
4. D.obtusa, Ch. Moore, mss. ; Lindl. in Journ. Hort. Soc. Lond. vol. vi. p. 270; G. Bennett, * Gather- 
ings, p. 351.—Aneitum, New Hebrides. In Sydney the bark of branches one year old was light-brown, 
the sereni branchlets green, without a trace of pruina, and the leaves without any pruinose covering on 
either side. i 
5. D. ovata, Ch. Moore, mss. in G. Bennett’s ‘ Gatherings of a Naturalist,’ p. 353.—New Caledonia. 
In Sydney, the bark of branches one year old was of a yellowish-brown, the nascent branches were green, 
and slightly pruinose; leaves, when just unfolding, slightly pruinose on the lower surface, but not at all on 
the upper; the leaves ultimately green on both sides, and towards the petiole and margin of the same yel- 
lowish-brown as the branches one year old. : m 
6. D. macrophylla, Lindl. in Journ. Hort. Soc. Lond. vol. vi. p. 271.—D. Perousii, Ch. Moore in Kew 
Journ. 1852, t. 5; G. Bennett, l.c. p. 351.—Vanikola or La Peyrouse Island, where discovered by Ch. _ 
Moore. I have no notes on this species from fresh specimens. It is just possible that it may also occur 
in Viti. The sterile specimen taken from a young plant which I gathered in Vanua Levu, and have figured 
in Plate LXXVI. Fig. 1, agrees in the shape of its leaves and thick medullose branches, with the branch 
figured by Hooker. : c
