50 PATAGONIAN EXPEDITIONS: BOTANY. 



It is probable that Lophocolea obvolutcefonnis (De Not.) Massal. also be- 

 longs here, although the published descriptions 1 of this species differ from 

 Taylor's specimen in a few minor details. The figure of L. obvoluta in 

 the Flora Antarctica does not well represent the species.

 Professor Massalongo has kindly confirmed my determination of these 

 specimens. In the Sullivant collection there is a drawing labeled " Jun- 

 germannia humilis" which was made from specimens collected by the 

 Wilkes Expedition. The drawing represents a plant which is identical 

 with Mr. Hatcher's specimens. As, however, Jungermannia hwnilis 

 Hook. f. & Tayl. 2 seems to have been a composite species and as Mitten 3 

 has applied the name to a plant without underleaves, it seems wisest not 

 to change the name of De Notaris' plant, yungennannia hiimilis is appa- 

 rently not represented in the Taylor herbarium. 



35. LOPHOCOLEA RIGENS (Hook. f. & Tayl.). 



Jungermannia rigens Hook. f. & Tayl. Lond. Jour. Bot. 3 : 461. 1844. 

 Dioicous : densely caespitose, yellowish-green ; stems ascending and 

 giving off numerous simple or subdivided, ascending or erect, lateral 

 branches, sparingly radiculose, the radicles in clusters at the bases of the 

 underleaves : leaves imbricated, obliquely inserted, erect-spreading, strongly 

 concave or convolute (especially on the branches), broadly ovate or orbic- 

 ular, bifid about one -fourth with acute, obtuse or lunulate sinus and acute 

 teeth, otherwise entire, more or less decurrent at antical base : underleaves 

 ovate, bifid one third or more with narrow sharp lobes, usually bearing on
