NEW HEPATICE. 



P. pectinata, Lind. is a much larger plant, has the leaves 

 distant, and the calyx short and campanulate. 



27. P. confertifolia, Tayl. ; caule laxe ceespitoso, erecto, 

 dichotome ramoso; ramis patentibus; foliis arete imbri- 

 catis, erecto-patentibus, ovato-oblongis, obtusis, apice den- 

 tatis, margine utroque subrecurvis ,• calyce demum axillari, 

 ex ovata basi ligulato, dentate-, folia perichsetialia erecta 

 elongata superante. 



Hab. South Brazil. Sellow, Hook. Herb. 



Olive-brown. Stems 2 inches high. Leaves slightly de- 

 current, when dry having both margins recurved, when 

 moistened nearly plane. This has an affinity to P. Bunburii, 

 Tayl. and it is distinguished by its longer, more erect, and 

 more deeply dentate leaves, which, too, are more narrow at 

 their bases. 



28. P. Dominicensis, Tayl. j caule laxe caspitoso, elongato, 

 erecto, ramoso, strictiusculo ; foliis imbricatis, patentibus, 

 majoribus, oblongis, apice obtusissimis, basi infera rotun- 

 datis, cristatis, margine infero apiceque longe ciliatis, mar- 

 gine supero subrecurvo ; calyce demum laterali, obovato- 

 campanulato, hinc fisso, ore ciliato. 



Hab. Dominica, Hook. Herb. 



Brownish-olive. Shoots 4-5 long, a inch wide, complanate j 

 branches few, irregular. Leaves scarcely decurrent, the peri- 

 chaetial conformable with the cauline. Pedicel exserted for 

 about £ the length of the calyx. Capsule ovate. This fine 

 species is allied to our P. Pichinchensis, and to P. superba, 

 Lind. differing from the former by the more crowded cilia of 

 the leaves and shorter calyx, from the latter by the leaves not 

 being falcate, and the calyx not alate; and from both by the 

 obtuse leaves. 



29. P. macrifolia, Tayl., cau le cajspitoso, adscendente, 

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

 concavis, linearibus, margine utroque revolutis, apice sub- 

 tridentatis, caeterum integerrimis. 



Hab. Peru, Hook. Herb, 



Tufts wide, browish-olive. Stems about 2 inches long,
