TJnona longiflora , Roxb., FI. Ind. ii. 668. 
There are specimens in Herb. Kew from Motley and 
Barber from Borneo, with no specific locality, which I 
cannot separate from the Indian plant; the leaves are, 
however, very glaucous on the back, with clearer marked 
reticulations, and the carpels more resemble those of U. 
dasymaschala. 
The species is a native of Assam and Chittagong.
