﻿422 Evans : Hepaticae of Southern Patagonia 



ently distinct, but there is so little of it that it would be unwise to 

 attempt to describe it. In the type-specimen a well-developed 

 leaf is almost longitudinally inserted and is attached by a very 

 broad base, the distance from side to side being about twice as 

 great as that from base to apex. The leaf is more or less dis- 

 tinctly divided into two unequal lobes ; the postical, which is 

 slightly the larger, is concave and rounded at the base and 

 extends beyond the stem, at the apex it is bidentate but is other- 

 wise entire; the antical lobe is decurrent and is irregularly 

 lobed and dentate. The leaf-cells average 25 fi in diameter. The 

 specimens collected on the Albatross expedition and referred by 



abvolutaeft 



In 



Dr. Hatcher's specimens the postical lobe is more coarsely and ir- 

 regularly dentate than in the type and the leaf-cells are a little 

 smaller, averaging 2 1 p. in diameter, but the plants are otherwise 

 so similar that they can hardly be separated. It it probable that 

 Lophocolea obvolidaeformis (De Not.) Massal. also belongs here, 

 although the published descriptions! of this species differ from 

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

 luta in the Flora Antarctica does not well represent the species.
