280 NEW HEPATICJE. 



plici, abbreviate, incrassato, repente, apice adscendente; 

 foliis arete imbricatis, concavis, sursum secundis, rotun- 

 datis, apicalibus spinosis, incurvis ; stipulis oblongis, spi- 

 nosis. 

 Hab. Near sulphur springs, New Zealand. On tufts of Musci ; 

 n. 258. 1844. Hook. Herb. 



Stems about f inch long, tumid, pale olive-green. Leaves 

 with their spinous teeth incurved as the talons of a bird ; the 

 upper more erect and oblong. Stipules observable only near 

 the summits of the stems. The male shoots are smaller; 

 between the terminating pair of their leaves are numerous, 

 crowded, pedicellated, whitish anthers, a distribution that 

 would indicate a peculiar genus. This species has the habit 

 of Gymnanthe Wilsoni, Tayl. The stems, however, are shorter, 

 the leaves more crowded and never bifid. A small specimen 

 only was seen. 



19. J. colpodes, Tayl. ; caule dense csespitoso, erecto, sub- 

 ramoso; foliis imbricatis, erecto-patentibus, secundis, or- 

 bicularis, bifidis sinu angusto ejusque margine recurvo ; lobis 

 subaequalibus, rotundatis ; pericheetialibus quadrifidis, basi 

 utrinque unidentatis ; stipulis bipartitis integrisve lanceo- 

 latis, basi utrinque subunidentatis ; calyce terminali, ex 

 angusta terete basi lineari-obovato, subcompresso, sursum 

 subplicato, ore laciniato, denticulate 

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



Tufts wide, dark olive-brown, two inches high. Stems 

 prolonged by one or two annual shoots. Leaves rather con- 

 cave. The inner pair of perichaetial leaves somewhat smaller 

 than the cauline. Pedicel about | inch long. Capsule shortly 

 oval. Our plant differs from Jung, plicata, Hartm., (if we 

 understood the characters given), by the erect stem, by the 

 equal lobes of the leaves, and by the calyx being by no means 

 split down on one side. 



20. J. longiscypha, Tayl. ; caule implexo, ramoso, surculis 

 adscendentibus ; foliis laxis, trifariis, subincurvis, biparti- 

 tis, segmentis setaceis, articulatis, perichajtialibus oblongis
