Stem 2-3 feet high, much branched. Leaves 3-4 inches long, 2~5 lines wide, 
with a thickish midrib, and slender pennate nerves. Pedicels 2-3 lines long ; ripe 
capsule an inch or rather more in length. Calyx-lobes very acute. Mr, Hewitson’s 
Specimens agree well with East Indian ones distributed by Drs. Hooker and Thom- 
son. It seems to be a common East Indian species.

in the upper part more or less villous ; leaves lanceolate or oblongo-

acute leaves, and shorter pedicels. But Dr. Gueinzius’ specimens are intermediate 
in both these respects. Leaves, including petiole, 3-4 inches long, }-4 inch wide.
