230 TASMANIAN HEPATIC^. 



oblong triquetrous calyx has the mouth beautifully 

 fringed, and one lip much longer than the other ; it has 

 usually three wings^ which are strongly dentate. The 

 perigonia occur about the middle of a shoot, and consist 

 of closely imbricated, adpressed, upright leaves, ventri- 

 cose at the base, their points standing out from the 

 stem ; the stipules of the perigonia are less compounded 

 than those of the rest of the stem, being, for the most 

 part, simply bifid. The capsule is oblong, splitting 

 into four elliptical valves, discharging numerous minute 

 round seeds and spiral filaments, with a double helix. 



This species approaches the European ,/, bidentata, 

 L. difiering from it by its smaller size, more deeply 

 notched leaves, their segments more elongated, by the 

 quadrifid stipules with entire segments, but, above all, 

 by the inequality of the two lips of the calyx. Lond.

Scarcely different from L. hidentata. Hook. Hd.

10. L. AMPLECTENS, llitten. Stems tufty, decumbent, 



vaguely sub-pinnately branched ; leaves imbricate, sub- 

 cj^uadrate, 2-fid, laciniffi acute, ampleetant. Stipules 

 ovate, 2-fid, outer segments one-toothed. (PI. ix.) 



Yellov.' -green or brownish. In size and habit very 

 nearly resembling the European Sarpanthus sciitaUis, 

 Spruce (J. scutata — Hook.), but its leaves and stipules 

 are of a different form, and were it not for the form of 

 the stipule being exactly that which prevails in almost 

 all the species of Lophocolea, it would rank nearer to 

 some Jungermannice.

 Oldfield. 



11. L. DECURVA, Mitten. Stems procumbent, nearly simple ; 



leaves ovate, bidentate, sinus small, dorsal margin long, 

 decurrent, ventral arcuate ; stipules wide, ovate, inflexed, 

 tri-partite, teeth recurved, subulate. (PL ix.) 



Beautiful green, one inch high, slender; leaves 

 imbricate, apices decurved ; stipules large, concave. 



A small plant, readily distinguishable by its concave 

 stipules, which have their two slender teeth bent back. 

 In general appearance it has more resemblance to some 

 sm.all forms of PlagiocMla Mmiritiana — Nees, than to 

 any Loplwcolece. (FL Tasm., n. 227.)
