1. Bonnaya brachiata, Link & Otto, Ic. PI. Sel. I. 25, t. 11. An

lowest decumbent below. Leaves oblong, obtuse or acute, margins 
thickened and sharply closely deeply serrate with teeth mucronate ; 
lamina -5 to 1-5 in. long; pedicels rigid about -25 in long ; bracts small. 
Calyx of 5 nearly free sepals -25 in. long. Corolla white or pink, -25 in. 
long. Capsule slender, spreading or erect, -5 to -6 in. long. Benth. in

Singapore: Wallich ! Pahang: Ridley! — Distrib. India, Indo- 
China, China, Malaya, Philippines. 
Wallieh’s Singapore specimen and one of Eidley’s from Pahang belong to the form 
distinguished by Bentham as IS. pusilla ; another Pahang gathering (Ridley 21G3) 
consists of genuine />’. brachiata, from which, however, IS. pusilla, though separable 
as a marked form, is hardly separable as a variety. 
Bonnaya reptans, Spreng. Syst. I. 41. A prostrate creeping 
slender herb with reddish stem, branches and leaves beneath ; branches 
diffuse spreading often 12 in. long. Leaves in distant pairs, obovate- 
oblong, obtuse, margins thickened and sharply serrate with mucronate 
teeth ; base narrow-cuneate passing into a petiole -25 in. long ; blade 
•75 to 1-25 in. long, -5 in. wide. Flowers opposite in terminal racemes 
sometimes 3 to 4 in. long ; pedicels rigid, -25 in. long ; bracts small.
