 paul, where it was collected by Wallich. It agrees with P. au- 

 rantiaca in the stipulas, but differs from that plant in the short 

 corollas, &c. ; and from P. nervosa in the teeth of the calyx 

 being acute, not obtuse, nor membranous.

 front of the leaves ; -panicles terminal, pedunculate, downy, with 

 the rachis compressed, and the branchlets opposite ; limb of the 

 calyx broadly campanulate, truncate. T? . S. Native of Ceylon.

 ing at the base ; leaves ovate-oblong, attenuated, smooth above,
