T)escriptive Notes on Papuan Plants. 49 
genuine A. solauacoa, especially as no fruits are available for com- 
parison. But Eoxburgli’s plant seems cpiitc distinct from what 
Thwaitcs regards as the true A. liumilis, the leaves not being chiefly at 
or towards the summit of the branchlcts and having less cojrious and 
less prominent veins, while the flowers are mostly terminal, nearly all 
paniculate and borne on shorter stalks and stalklets ; further (as well 
pointed out by Thwaitcs) the fruits are black not bright-red. Should 
the Papuan plant prove distinct, then the name of the variety would 
become specific. 
The genus Pimelandra can only bo regarded as a section of Ardisia ; 
but the East- Australian A. Pseudo- Jambosa should bo transferred 
to Labisia, notwithstanding considerable difference in habit and 
inflorescence ; it would however form a peculiar section in that genus.
