Labillardiere's figure; but they bear only half-grown flower-buds, 

 sufficing however to show that the flowers are tetrandrous and appa- 

 rently perfect. What Labillardiere takes for the putamen of the 

 drupe, is the testa of the seed, as is evident from his figure. — The 

 leaves of our plant are occasionally simple. 



14. ACRONYCHIA, Forst 



This genus, of which our collection considerably extends the 

 number of the species, differs from Euodia in the double number of 

 stamens and the gynobasic disk; from Melicope in the valvate aesti- 

 vation of the corolla; and from both in the complete union of the 

 carpels into a compound ovary, ripening into a drupaceous or fleshy- 

 capsular fruit, which when dehiscent is loculicidal. The flowers are 

 polygamous in all our species, and probably in the whole genus, as in 

 Euodia, Ptelea, &c.

A. glabra; foliis membranaceis amplis, aliis integris aliis trifoliolatis, 

 foliolisque ovalibus oblongisve utrinque acutis; cymis multifloris pani- 

 culatis compositis breviter pedunculatis ; jhribus polygamis, fcemineis

Hab. Tutuila, one of the Samoan or Navigators' Islands. 



Shrub, or small tree, glabrous throughout, with much the habit of 

 Melicope ternata; but the leaves more ample, some of them simple and 

 entire, while others are trifoliolate on the same branches, membra- 

 naceous in texture, pale and dull, opposite ; the simple leaves oval or 

 oval-oblong, more or less acute at both ends, or sometimes obtuse, 

 loosely feather-veined, thickly punctate with rather opaque dots, 3 to
