368 NEW HEPATICiE. 



latis, acuminatis, divaricatis, subflexuosis ; stipulis bifidis, 



segmentis subulatis extus unidentatis. 

 Hab. Cape Horn ; Dr. Hooker. 



Patches whitish-green. Stems about 1 inch long, branched 

 towards the base. Leaves loosely set, largely cellulose, their 

 sinus acute, divided for half their length into two divergent 

 acuminate segments, the dorsal margin decurrent and re- 

 curved. The perigonia are terminal spikes of closely adpressed 

 leaves, whose tumid bases contain the anthers, and whose 

 subdivisions are shorter than of the cauline leaves. Allied to 

 L. leptantha, Hook. fil. et T. likewise from Cape Horn, 

 differing by its smaller size, by its leaves with narrower bases, 

 and summits more deeply divided, and by the bipartite 

 stipules. 

 7. L. triacantha, Hook. fil. et Tayl. ; caule implexo, pro- 



cumbente, vage ram so ; foliis complanatis, approximatis, 



patentibus, oblongo-ovatis, trispinosis ; stipulis subquadra- 



tis, bifidis, segmentis bilaciniatis, laciniis subulatis. 

 Hab. East Falkland, Lyall. n. 67. New Zealand, Herb. 



Mus. Paris. 



Patches thick, dusky olive-green. Stems about 1 inch long, 

 branches few, patent. Leaves scarcely imbricating at their 

 bases, at right angles to the stem, oblong, with two sinuses 

 and three subulate spines. Stipules free, erecto-patent, 

 having four subulate segments. It is allied to our L. chloro- 

 phylla, from New Zealand, which, however, is a smaller 

 plant and has shorter, wider, subsecund leaves, as also sub- 

 rotund dentate stipules. 



8. Lepidoziciy Nees. 



1. L. filipendula, Tayl.; caule laxe csespitoso, erecto, filiformi, 

 pinnato, arhizo; ramis attenuatis, dependentibus ; foliis 

 minutissimis, distantibus, quadratis, caule angustioribus, 

 cauli adpressis, erectis, caulinis subtrifidis, rameis stipu- 

 lisque bifidis, segmentis spiniformibus.
