Amyris Purpusii P. Wilson, sp. nov. 
A small tree with grayish branches. Young twigs, branches 
of the inflorescence, and the petioles minutely hispidulous. Leaves 
opposite ; leaflets 3, petioluled, elliptic to ovate, 2-3.8 cm. long, 
1.2-2.4 cm. broad, coriaceous, rounded and somewhat emarginate 
at the apex; lustrous above, dull and minutely puberulous on the 
veins beneath, the margin entire or obsoletely crenate, lateral leaf- 
lets cordate at the base; inflorescence 3-5 cm. high; flowers not 
seen, on triangular, ciliate ; drupe (immature) narrowly obovoid, 
4-5 m 
Pee collected in Barranca de Santa Maria, Zacualpan, State 
of Vera Cruz, Mexico, C. A. Purpus 2355. 
Related to Amyris elemifera L. and A. balsamifera L., but dif- 
fering from both in the lateral leaflets, which are cordate at the 
base and rounded at the apex. The obovoid fruit and presence of 
hairs on the branches of the inflorescence seem to indicate that this 
species is closer to A. dalsamifera L. than to A. elemifera L., 
which usually has a globose or subglobose fruit and the branches 
of the inflorescence glabrous.
