This is distinguished from the typical species by its narrower, 
acute but not acuminate leaves, by their nervation, by its much 
shorter petioles, and by the number of the floral parts. The 
leaves are 4 inches long, 1 ^ inch broad, on a petiole 3 lines long ; 
the ^ raceme is 2-2j inches long, its branches 3 lines, and their 
three alternate pedicels 1-2 lines long ; the three outer sepals 
are minute, dark, with ciliated margins the four inner sepals 
quite glabrous, submembranaceous, marked with numerous 
coloured linear spots ; the petals, half their length, are fuscous ; 
the filaments are of the same length, slender, and aggregated 
on a short central receptacle.

This is a trailing shrub, found in low jungle. The leaves are 
2|-4 inches long, 1^ inch broad, on a petiole 4-7 lines long ; 
the^J raceme is 1-1 1 inch long.
