Temperate Himalaya; from Bhotan to Kumaon, alt. 7000-10,000 ft., frequent. 



A decumbent, weak species, with branches 6-8 in. long, closely resembling C. op- 

 positifolium, L., which only differs in having its leaves entire or obsoletely crenate. 



Maximowicz (in Bull. Acad. Petersb. Mel. Biol. ix. 767) has founded a new Hima- 

 layan species C. sulcatum, Maxim on Wall. Cat. 438 ; which differs from C. nepalense 

 in having the seeds profoundly 12-sulcate ; but the examples of Wall. Cat. 438 at Kew 

 exhibit the smooth seeds of C. nepalense.
