is not on proper stems ; the calyx is more nearly rotundate, 

 and the leaves more unequally divided, while their segments 

 are apiculate. 



5. J. scitula, Tayl.j caule implexo, prostrato, subsimplici; 

 foliis subverticalibus, imbricatis, erecto-patentibus, con- 

 cavis, rotundato-obovatis, apice trifidis, segmente ventrali 

 majori, integerrimis ; gemmis foliorum segmenta termi- 

 nantibus, minutissimis, rubris. 



Hab. North America. J. Drummond, Hook. Herb. 



Patches wide, but shallow, tawney-olive. Stems bound 

 down by numerous rootlets, slightly ascending at their sum- 

 mits. Leaves pale, the notches shallow, the segments ovate, 

 acute, the two dorsal the smaller. No stipules. The leaves 

 are more vertical, less decurrent, and have a narrower base 

 than in J. barbata, Schreb.; besides, their emargination into 

 three pieces is more limited to their summits, and the cel- 

 lules are much minuter. 



6. J. Tasmanica, Hook. fil. et Tayl. ; caule laxius ceespitoso 

 sparsove, procumbente, demum subramoso ; foliis imbri- 

 catis, secundis, erecto-patentibus, ex lata basi oblongis, 

 apice rotundatis, margine subrecurvis, integerrimis ; retis 

 maculis majoribus. 



Hab. With Scapania Urvilleana, Mont. n. 53. Van Diemen s 



Land. Gnnn, 1844. Hook. Herb. 



Stems mostly scattered, sometimes aggregated, about 1 inch 

 long, reddish-brown, the younger parts whitish-green. Leaves 

 closely imbricated, secund on the dorsal edge of the stems, 

 rarely with a shallow notch. In one instance, only a single 

 oblong and entire stipule was observed about the middle of 

 the stem. The present is closely allied to J. Orcadetisis, 

 Hook, but the leaves are longer, have commonly a rounded 

 and entire summit, their margins are less recurved, while 

 their cells are far larger and more distinct.

 oblongis, latis, obtusissimis retusisve, integerrimis, sub- 

 marginatis, perictuetialibus duobus interioribus minoribus,
