all decurved, and are more attenuated above. The calyx too 

 is subtruncate and its mouth nearly entire. 



12. P.fissidentoides, Tayl. ; surculis laxe csespitosis, erectis, 

 simplicibus ; foliis alternis, distichis, approximatis, paten- 

 tibus, planis, lineari-oblongis, obtusissimis, apice den- 

 tatis. 



Hab. Sandwich Isles. Menzies. 



Very pale olive brown, shoots about \\ inches high, 

 widest in the middle, anterior and posterior margins of the 

 leaves nearly paralel. The simple, shorter shoots and wider 

 leaves destitute of cilise, easily distinguish this from P- bur- 

 sat a, Lind. 



13. P. phalangea, Tayl. j caule caespitoso, erecto, fasciculato, 

 ramis dichotomis, strictiusculis ; foliis arete imbricatis, 

 erecto-patentibus, secundis, semicordatis, obtusis, dentatis, 

 margine dorsali subrecurvo, decurrente, ventrali cristato, 

 gibboso. 



Hab. Nepal. Wallich, 1820. 



Tufts olive-brown, stems slender, two inches high. Leaves 

 convex, their denticulation short and at irregular distances. 

 The present differs from P. semidecurrens, Lind., by the want 

 of fibrils to the stems, and by the narrower tops of the leaves ; 

 and from P. Nepalensis, Lind., by the more decurrent leaves, 

 which are more minutely denticulate ; and from both by the 

 close imbrication of the secund foliage. 



14. P. exigua, Tayl.; caule csespitoso, erecto, crassiusculo, 

 subramoso, flagellifero; foliis distantibus, patentibus, ex 

 angusta basi rotundato-ovatis, bifidis, integerrimis, seg- 

 ments sinuque subacutis, margine dorsali subrecurvo, 

 ventrali subgibboso, subdenticulato. 



Hab. On trees at Cromaglown, and wet rocks at Knockavo- 



hila, County Kerry. 



Tufts dense, short, olive. Stems scarcely \ inch high, 

 usually naked above, except at the very summit where a 

 flattish capitulus of leaves occurs. Leaves remote, the base 

 very narrow, hence easily detached from the stems ; the
