﻿424 Evans : Hepaticae of Southern Patagonia 



very 



This distinct little Loplwcolea does not seem to have been re- 

 corded since its original discovery in the Falkland Islands. Dr. 

 Hatcher's specimens agree very closely with the sterile type mate- 

 rial in the Taylor herbarium, and I have given a full account of the 

 species because the original description is far from complete and 

 the figure given in the Flora Antarctica does not adequately repre- 

 sent the plant 



apparently spreading by means of small branches, which, when 

 dry, easily become detached. 



The authors of Jungermannia rigens compared it with the 

 European /. Francisci Hook, and, in the Synopsis, it is placed close 

 to that species ; the position of the branches, however, which are 

 produced near the postical basal angle of the subtending leaves 

 would at once remove it from the genus Cephalozia in which / 

 Francisci is now included. L. rigens belongs in the puzzling group 

 of Lophocoleac with bifid leaves. Its small size and yellowish- 

 green color, the curious rolling up of its leaves, which often gives 

 the branches a worm-like appearance and the slight modifications 

 which its bracts undergo will serve to distinguish it.

The figures of this species in the Flora Antarctica give a false 

 idea of the underleaves, which are much narrower than is repre- 

 sented. The quoted illustration of Jungermannia data, however, 

 is more accurate in this respect. The Patagonian plants agree 

 closely with the types of/, vasculosa in the Taylor Herbarium.
