HEPATICA ANTARCTICA. 91 
(Lejeunia, Libert.) 
26. J. pterota, n. sp.; caule implexo prostrato vage ramoso, 
foliis approximatis patentibus ovato-oblongis apiculatis 
integerrimis lobo inferiori minuto oblongo involuto uni- 
dentato, stipulis rotundato-oblongis subimbricatis bifidis 
integerrimis, calyce demum laterali obovato alato tubi- 
: fero. 
Has. St. Helena. 
Patches one or two inches wide, dusky brown. Stems 
scarcely one inch long, weak, flexuose, with short, irregular 
branches. Leaves scarcely imbricated, obtuse yet with a 
minute apieulus. Stipules large, broadly elliptical, lying close 
on the stem. Calyces several on the same stem, obovate, 
with five considerable folds or wings. Perigonium a lateral, 
obtuse, oblong spike. The present is very like Lejeunia sor - 
dida, Nees, from Java, but may be recognised by the apicu- 
late leaves which are less imbricated, and by the longer and 
narrower stipules. 
27. J. Ascensionis, n. sp; caule arcte implexo prostrato 
ramoso, foliis imbricatis patenti-decurvis oblongis apice 
subrotundis apiculatis integerrimis lobo inferiori minuto 
oblongo involuto unidentato, stipulis rotundato-oblongis 
bifidis integerrimis. 
Has. Ascension Island. 
Patches three or four inches wide, pale brown. Stems an 
inch long, irregularly branched. Leaves somewhat imbri- 
cated. Cellules of the leaves rather large. Stipules broad 
as long. This closely resembles our J. pterota, and may be 
distinguished by the greater size, paler colour, by branch- 
ing principally towards the base of the stem, by the de- 
curved leaves, which too are not so regularly apiculate, and, 
above all, by the larger cells of the leaves. Calyces have 
not been observed on this species, yet they are frequent on 
the other. D
