NEW HEPATICiE. S81 



5. M. recurva, Tayl.; caule laxe csespitoso, adscendente, 

 tripinnato, surculis gracilibus, complanatis; foliis imbri- 

 catis, erecto-patentibus late triangulari-ovatis, integerrimis, 

 raargine dorsali gibboso, ventrali recurvo ; lobulis compli- 

 catis, linearibus, cauli subadpressis ; stipulis lineari -trian- 

 gularibus, acutiusculis, apice recurvis basi amplexantibus, 

 decurrentibus ; calyce sessili, laterali, orbiculari-ovato, ore 

 angustato, plicato, subquadridentato. 



Hab. Colchaquej South America; n. 44. Hook. Herb. 



Pale olive-green. Stems 5-6 inches long ; branches patent. 

 Leaves closely imbricated, short ; the lobule united by its 

 entire base, slightly curved next to the stem. Perigonia and 

 Perichatia on the anterior edges of the branches ; the former 

 are very short spikes ; the latter composed of a few subentire 

 leaves. This is allied to our M. gracilenta, from Con- 

 ception, hut the leaves are smaller and more crowded, the 

 lobule joined by its entire base to the leaf, the stipules more 

 narrow and acute, and the calyces narrower. 



6. M. gracilenta, Tayl. ; caule laxe implexo, adscendente, 

 subbipinnato ; ramis attenuatis, decurvis ; foliis subimbri- 

 catis, subpatentibus, late oblongo-ovatis, obtusis, apicula- 

 tis, integerrimis, margine ventrali recurvo ; lobulis ligu- 

 latis, margine reflexis, subdecurrentibus ; stipulis ex de- 

 currente cordata basi oblongis emarginatis, subbidentatis ; 

 calyce sessili, laterali, rotundato, compresso, convexo, ore 

 minuto denticulato ; foliis perichaetialibus subdentatis. 



Hab. Conception ; n. 152, Beechey, Hook. Herb. 



Patches loose, tawney olive. Stems 2-3 inches long; 

 branches subfastigiate towards the tops of the stems. Peri- 

 c/uetia small compared with the calyx, their leaves patent, 

 acute, subdentate, their lobules lanceolate, their stipules 

 nearly round, emarginate, strongly dentate. Pedicel scarcely 

 exserted. Capsule oblong. This has some resemblance to 

 J ung. distans, Schweinitz, (which, probably includes both 

 M. Porella, Nees, and M. rivularis, Nees,) the similitude, 

 however, is limited to the small-mouthed and round calyx ;
