FLORA VITIENSIS. 49 
simplicibus v. abrupte pinnatis; floribus axillaribus v. terminalibus, solitariis racemosis corymbosis 
Y. paniculatis, inconspicuis.—Empleurosma, Bartl. in Lehm. Plant. Preiss. vol. ii. p. 228, 
D.z eriocarpa, Smith, of which there is a specimen collected by Menzies in the British Museum, and 
D. viscosa, Linn, (of which D. spathulata, Smith, is a mere mountain form), are the only two representatives 
of Dodonea in the Pacific, the occurrence of D. triquetra, Andr., being doubtful. What A. Gray and I 
took for the latter species is one of the innumerable forms of D. viscosa, as justly remarked by Bentham 
(Fl. Austr. yol. i. p. 475). 
1. D. viscosa, Linn. Mant. 238; Benth. Fl. Austr, vol. i. p. 475; fruticosa, glabra, viscosa, 
ramulis teretibus, junioribus seepe compressis y. subtriquetris; foliis simplicibus oblongo-lanceolatis, 
anguste lanceolatis, oblongo-cuneatis v, lineari-cuncatis, apice obtusis, acutis y, acuminatis, basi in 
petiolum attenuatis, integerrimis vy. obscure sinuatis, v. apice subtridentatis; racemis simplicibus v, 
paniculatis, axillaribus v. terminalibus; sepalis ovatis; stylo clongato; capsulz alis rotundatis y,

teste Williams.— Very common on-the leeside of the large islands, and in the eastern parts of the 
group (Seemann! n, 72; U.S. Expl. Exped.). Also collected in the Sandwich (Nuttall! Menzies ! 
Macrae!) and Society Islands (Barclay! Banks and Solander! Forster !), and New Caledonia (Cap- 
tain Cook! M*‘Gillivray!). Common in New Zealand, Australia, and America. 
Orpo XXXI. ANACARDIACEA:, 
I. Rhus, Linn. Gen. n, 369; Benth. et Hook, f. Gen, p. 418. Flores polygami. Calyx

planiuscule ; radicula uncinata, brevis.—Arbores v. frutices, seepe verniciflus v, succo caustico sca- 
tentes; foliis alternis simplicibus, 1—3-foliolatis vy. imparipinnatis, foliolis integerrimis v. serratis; 
paniculis axillaribus y, terminalibus, bracteatis; floribus parvis. 
The only other known Polynesian species of Rhus, besides the two enumerated below, is R. Sandwich- 
ensis, A. Gray, Bot. Wilkes, p. 809, of which there are fine specimens, collected in Hawaii by Macrae, at 
the British Museum, and which I hold to be identical with 2. semialata, Murr. (20. Javanica, Linn.) and 
fi, Chinensis, Mill. The doubtful Rhus atra, Forst., has been named Semecarpus atrum, Vieill. 
1, R. simarubzefolia, A. Gray, Bot. Wilkes, p. 367. t. 44; glabra; foliis pinnatis, rachi 
superne margimata; foliolis subsessilibus 7-9 oblongis obtusis basi inzequilateris integerrimis supra 
nitidis subtus pallidis; panieculis axillaribus laxifloris folio paulo brevioribus; calyce 5-lobo; petalis 
5. ovali-obovatis (albis); staminibus 5; drupis glabris lucidis (nigris),—Macuata coast of Vanua 
Levu (U. 8. Expl. Exped.; Seemann! n, 95). 
A small tree, with fine bright-green foliage and white flowers. It is closely allied to R. rhodanthema, 
FF, Muell., from which, however, it may ut once be distinguished by its white flowers.
