li This plant differs from the trpe FR. setosa in the anthers, the cells of which ave 
sightly Unequal, divaricated in the lower half and muticous : it differs from Hygrop I 
it the corulla which is altogether as of Ruellia, and from Ruellia, in the pollen. #0 
i; nical characters, it is a Hemigraphis. t is very possible that Calophanes hyssopr- 
ous, Nees (recorded below at the end of Dyschoriste), may be allied.
