58 CampamilacecF. [Wahlenbers^ia. 



All anth. with conspicuous white bristly hairs on the back, 

 but none with a beard or tuft. 



Open ground in the montane zone, 4000-7000 ft., and carried down to 

 3000 ft., or even lower, along the course of streams ; common. Fl. Dec- 

 April ; dull purplish-pink, or white often with pink tips. Moon's locality 

 is ' Four Korles.' 



Also in the mountains of S. India. 



I cannot separate L. cxcelsa, Lesch. ex. Roxb. as a species. It is a 

 characteristic form abundant at N. Eliya, and has the flowers very 

 densely arranged in an unbranched spike and of a dull purplish-pink 

 colour, and the 1. densely pubescent beneath. At lower elevations the 

 inflorescence is more lax and often branched, the flowers usually white 

 and the 1. nearly glabrous. I have never seen any flowers of the colour 

 shown in Wight, 111. Wight considered the Ceylon plant as a separate 

 species, intermediate between excelsa and nicotianafolia, both of which 

 he also kept up as distinct. Var. trichandra is scarcely worth separa- 

 tion. 



The leaves and seeds are acrid, and probably poisonous ; and the plant 

 is often called ' wild tobacco' by the English. 



Isotoi7ia lojigifiora^ Presl., is a W. Indian plant, not uncommonly found 

 as a weed by roadsides. It has an acrid, poisonous milky juice. 



\Ceplialostigma Schimperi, Hochst., is given for Ceylon in Fl. B. Ind. 

 iii. 428, but I do not know on what authority. There is no specimen 

 from here in Herb. Kew.]
