Var. p. hamatus Schimp. Synops. I.e. 



Stems shorter, more robust ; leaves very densely crowded, broader, 

 hamato-secund. 



In N. Uist with the type. 



This fine plant approaches very close to C. Schwarzii, from which it can 

 best be distinguished by the tomentose stem and suddenly inflexed margin of 

 the leaves ; the hoary poii't of C. atrovirens separates it from that species.
