476 HEPATICA ANTARCTICA. 
few, alternate, distant except at the very summit of the stem, 
in figure not unlike Helix putris, L. | 
The present can scarcely be confounded with any other of 
the Radule of Nees, on account of its minuteness, its colour 
and its tumid leaves. 
51. J. flavifolia, n. sp.; caule implexo procumbente ra- 
moso, foliis imbricatis concavis patentibus integerrimis, lobo 
superiori ovato acutiusculo, inferiori elliptico involuto uni- 
dentato, calyce terminali ex angusta basi lineari-oblongo, 
compresso truncato integerrimo. 
Has. On J. uncialis (nob.), Cape Horn. 
Patches minute, of a lively pale yellow colour. Stems 
scarcely one quarter of an inch long, irregularly branched ; 
branches patent. Leaves closely imbricated, very concave, 
the top of the upper lobe frequently incurved, hence its 
being acute may escape notice; the lower lobe with a re- 
markable tooth at its outer termination, the rest incurved. 
Perichetial leaves longer than the cauline and more patent, 
the inner one with a flat oblong and rounded summit. The 
narrow base of the calyx taper, and scarcely covered by the 
perichetium. Capsule spherical or nearly so, pale brown. 
Perigonia are terminal, whitish, linear spikes, with closely 
imbricated tumid short leaves, leaving a channel in the mid- 
dle of the spike along the stem. The acute and concave 
upper lobe of the leaf, and the minuteness of this species 
will readily distinguish it from every other known.
