398 NEW HEPATIOE. 



Hab. Maritime rocks. Niger expedition. Vogel. Hook. Herb. 

 Tufts extensive, flat, olive-green. Stems 3-4 lines long, 

 very slender. Leaves rather flaccid, largely cellulose, their 

 lobule inconspicuous. Stipules scarcely wider than the 

 stems. Perichsetial leaves similar to the cauline. Perigonia 

 terminal. Calyx twice as long as the leaves. In Jung, tenera, 

 Sw. the leaves are much larger, more distant, and attached 

 with a wider base. 



23. L. tenella, Tayl. ; caule subdisperso, procumbente, sub- 

 ramoso; surculis elongatis, subsimplicibus ; foliis imbn- 

 catis, erecto-patentibus, concavis, rotundato-quadratis, mar- 

 gine recurvis, integerrimis ; lobulis erectiusculis, ovatis, 

 involutis, subunidentatis ; stipulis majoribus, rotundato- 

 ovatis, bifidis, segmentis subacutis. 



Hab. On Dicranum fragile, Hook. Sincapore. Wallich. 



Patches loose, pale yellowish-olive. Stems about 1 inch 

 long, fine as human hair, when dry appearing nodulose. A 

 single calyx was observed ; it was obovate, 5-angled above, 

 and crowned with a minute tube. Ours differs from L. 

 cemula, Gottsche, by the less concave and less patent leaves, 

 and by the larger stipules with wider segments. 



24. L. punctiformis, Tayl. ; caule exili, sparso, procumbente, 

 subramoso ; foliis distantibus, erectis, ovatis, obtusissimis, 

 concavissimis, integerrimis; lobulis subsequalibus, ova- 

 tis, involutis ; stipulis minutis, bipartitis, segmentis linean- 

 bus, acutis. 



Hab. East Indies. Br. Wight. Dr. Greville's Herb. 



Stems inconspicuous without a lens ; scarcely 1 line long. 

 Leaves alternate, distant, erect or nearly adpressed to the 

 stem, like little spherules with the side next to the stem 

 cut to admit the involute lobules. This approaches our 

 L. bullata, likewise a tropical plant; the leaf, however, is 

 more spherical, the lobule quite as long, and the plant is 

 larger. 



25. L. bullata, Tayl. ; caule exili, sparso, procumbente, sub- 

 ramoso ; foliis subapproximatis, erectiusculis, ovatis, rotun- 

 datis, concavissimis, integerrimis; lobulis latis, ovatis,
