FLORA VITIENSIS. 49 
simplicibus v. abrupte pinnatis; floribus axillaribus v. terminalibus, solitariis racemosis corymbosis 
v. paniculatis, inconspicuis.—Empleurosma, Bartl. in Lehm. Plant. Preiss. vol. ii. p. 228. 
: D. 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 J 
took for the latter species is one of the innumerable forms of D. viscosa, as justly remarked by Bentham 
(Fl. Austr. vol. i. p. 475). 
l. D. viscosa, Linn. Mant. 238; Benth. Fl. Austr. vol. i. p. 475; fruticosa, glabra, viscosa, 
ramulis teretibus, junioribus sepe compressis v. subtriquetris; foliis simplicibus oblongo-lanceolatis, 
anguste lanceolatis, oblongo-cuneatis v. lineari-cuneatis, apice obtusis, acutis v. acuminatis, basi in 
petiolum attenuatis, integerrimis v. obscure sinuatis, v. apice subtridentatis; racemis simplicibus v. 
panieulatis, axillaribus v. terminalibus; sepalis ovatis; stylo elongato; capsule alis rotundatis v. 
basi attenuatis.— Parkins. Drawings of Tahit. Pl. t. 42 (ined.). Nomen vernac. Vitiense, ** Wase,” 
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. |

The only other known Polynesian species of Rhus, besides the two enumerated below, is R. Sandwich- 
ensis, A. Gray, Bot. Wilkes, p. 309, of which there are fine specimens, collected in Hawaii by Macrae, at 
the British Museum, and which I hold to be identical with R. semialata, Murr. (R. Javanica, Linn.) and 
R. Chinensis, Mill. The doubtful Rhus atra, Forst., has been named Semecarpus atrum, Vieill.

A small tree, with fine bright-green foliage and white flowers. Tt is closely allied to R. rhodanthema, 
F. Muell., from which, however, it may at once be distinguished by its white flowers. TM ;
