160 Contributions towards a Flora of Ceylon. 



Obs. — The above description is taken from a drawing in 

 the Library of the Royal Botanic Garden, which was made 

 from a specimen brought from the Hunnisgiria range, in the 

 year 1839, by Mr. Lear, who was then Officiating Superin- 

 tendent of the Garden. In habit the plant approaches 

 nearest to the next species, but is well distinguished from it 

 by the much larger size of the corolla, which is besides more 

 distinctly bilabiate, and of a pale rose, not yellow, colour. 

 The filaments are moreover represented as glabrous.

 5-fido extus piloso-pubescente, lobis ovatis acutis aequalibus, 

 corolla (lutea) calyce duplo longiore, limbo patente, laciniis 

 rotundatis subaequalibus integris, filamentis glanduloso-pi- 

 losis, antheris oblongis, calcaribus erectis acuminatis, stig-
