lanceolate leaves readily distinguish it.

Differs from A. stylidioides, Reichb. f., of which it has much of 
the general appearance, in its more diffuse panicle, with more 
slender branches, its more slender ovaries and narrower segments. 
The stamens, staminode, and style are very similar in the two 
species. 
Motley’s Bornean specimens, mentioned at p. 239 as probably 
belonging to an undescribed species (which I have since discovered 
in his MSS. to have flowers “ white”), is remarkably similar in 
general appearance; but as the fruits are only two thirds as long 
as the undeveloped ovaries of A. gracilis, I hardly think they can 
belong to the same species.
