 trees. Fr. Oct. Nov.— This and the following species are so peculiar 

 in the confervoid structure of their foliage, that they cannot be con- 

 founded with any other.

Mr. Wilson has satisfied me that the present, as well as the- five preceding 

 species, is really furnished with stipules. It is extremely unlike an\ other 

 in its essential characters, and the var. £. (and that, never in fructification ) 

 has alone been found in Britain. The var. «., with calyces and young 

 capsules, I have figured in the Br. Jung, from Linnaeus' own specimens. 



This species grOWS in dense soft tufts ofi \ el low --reel) colour.
