420 FLORA ANTARCTICA. \Fuegia, the 



Var. /3. foliis laxe imbricatis substriatis, theca ovata, operculo conico. 



Hab. Herrnite Island, Cape Horn ; var. /3. on moist rocks and at the roots of trees ; scarce. 



Caules 2-3-unciales, rami ascendentes. Folia falcato-secunda, plicato-striata, serrulata, nervo ultra medium 

 producto, luteo-fusca, subspadicea, in var. (3. laete viridia. Seta semiuncialis, brunnea. Theca horizontalis, turgida, 

 sub ore contracta, nifa. Perislomium externum ferrugineum, internum flavum. 



This moss resembles H. aduncum in everything but the scabrous seta, and the serrulate leaves ; the var. /3 again 

 approaches very nearly to some varieties of H. velutinum.

Hab. Falkland Islands, common in watery places, rare in fruit. 



Apparently the moss mentioned by Gaudichaud under the name of H. aduncum, to which indeed it is nearly 

 allied. It differs from H.fiuitans, in its very strong, often percurrent nerve. The leaves vary in length.

Hab. Hermite Island, Cape Horn; with H.amosnum (barren). 



In the Hookerinn Herbarium we find a Brazilian specimen, apparently authentic, of H. lithophilum, labelled 

 "supra lapides rivulorum in novo Friburgo ", but consisting of two different species mixed together; and as the 

 description in Fl. Bras, appears to have been drawn up from both, we append a diagnosis of the other species.*
