 subrotundo, sursum plicato, ore albido, denticulate 

 Hab. Peru. Prof. W. Jameson. 



Tufts loose, brownish-purple. Shoots 1 inch long, the 

 fertile incrassated above. Pericheetial leaves two or three, 

 wider than the cauline, erect, their inner margin undulate. 

 Calyx nearly round, obtuse. Very like the preceding ; but its 

 stems, leaves, and calyces are much shorter and wider. 



3. J. anacampta, Tayl. ; caule ceespitoso, adscendente, subra- 

 moso ; foliis imbricatis, subsecundis, obovatis, ex basi am- 

 plexante reflexis, canaliculars, bilobis, segmentis eequalibus, 

 ovatis, obtusiusculis, ventrali basi uniciliato \ calyce demum 

 laterali, cylindraceo, inflato, obtuso, sursum subplicato, ore 

 minute dentato. 



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

 Patches wide, tawney-brown. Stems nearly 1 inch long, 

 sparingly branched, squarrose with recurved leaves. Calyx 

 naked below, the base narrower than the inflated summit. 

 Differs from J. incumbens, Lind. et Lehm., by the greater 

 size, the more obtuse lobes of the leaves, and by the obovato- 

 cylindraceous calyces. 



4. J. supina, Tayl. ; caule implexo, prostrato, subsimplici, 

 sursum incrassato ; foliis laxis patentibus, intequaliter bi- 

 fidis, segmento ventrali majori, ovato, dorsali lanceolato, 

 utroque apiculato, integerrimo ; foliis pericheetialibus latiori- 

 bus, trifidis, apiculatis, dentatisque j calyce terminali, obo- 

 vato, inflato, oris segmentis apiculato-dentatis.

Herb. 



Stems scarcely 3 lines long, radicating. Leaves of the 

 infertile shoots more distant, more narrow, and more unequally 

 divided ; in the fertile the pair below the pericfuetium are 

 trifid and entire, while the perichaetial are not only trifid but 

 also dentate. Calyx short, obovate, rather large for the size 

 of the plant. Perigonia terminal, their leaves with tumid 

 bases, each containing one or two pedicellated anthers. Re- 

 sembles some states of J. bicuspidata, L., but there the fruit
