HAB. Moist banks and rocks, not uncommon. 



In this species the upper leaves are often secund, all of them 

 of a glossy, generally deep yellow green. Hedwig's H. plu- 

 mosum, (now called by authors H. salebrosum,) has striated 

 leaves; and the whole plant so nearly resembles, (as Mr. 

 Turner has observed,) H. lutescens, that we know of no charac- 

 ter by which it may be well discriminated from it, except the 

 smoothness of its fruitstalks. Specimens of Hedwig's H. fla- 

 gellare perfectly accord with H. plumosum, and H. alpinum is 

 not to be distinguished from it.

HAB. Woods in alpine countries, and among rocks. 

 This is a small species, rarely exceeding an inch in length ; 

 the leaves standing out nearly horizontally on each side of the 

 stem, on which account Wahlenberg has brought it into his
