262 NEW BBPATICJS. 



of two erect, rotundato-ovate, dentato ciliate leaves. The 

 calyces observed were not fertile, bearing barren pistilla, 

 shortly obovate, with a wide obliquely truncate mouth, the 

 higher part of which was the more strongly ciliated. 

 Ours resembles P. pectmata, Lindl. It differs by the pale 

 colour, wider shoots, wider ba'ses of the leaves, which are 

 more convex, their denticulation more spinous, their cells are 

 wider. In P. tenuis, Lind., likewise from Nepal, the perichae- 

 tial leaves are far shorter than the calyx, and the cauline 

 leaves are more distant and more minute. 



8. P. Kamounensis, Tayl. ; surculis csespitosis, erectis, subra- 

 mosis, subtus hirsutis, apice incurvis; foliis imbricatis, 

 subpatentibus, secundis, convexis, dimidiato-cordatis, bast 

 lucido-nerviis, margine superiori decurrente, inferiori smu- 

 ato-crispo, utrisque recurvis, dentatis.

Tufts rather loose, brownish-olive, scarcely 2 inches high. 

 Shoots simple, but usually rising in pairs from the same 

 point j their inferior side beset with numerous, flat, simple 

 filaments, which resembling roots, yet are placed on shoots 

 not touching the ground. Leaves dentate round their entire 

 margin ; the lower leaves minute. From P. corrugata, Lino. 

 the present is at once distinguished by the absence of stipules, 

 by the root-like filaments on the inferior side of the shoots, 

 the smaller but more extended denticulation of the leaves as 

 well as by the pale yellow, transparent, elongated spot at the 

 middle of their bases, representing a nerve. 



9. P. deflexirama, Tayl. ; caule laxe csespitoso, erecto, pin- 

 nato ; ramis distantibus, eomplanatis, subsimplicibus, 

 deflexis, foliis subimbricatis, paten ti-decurvis, dimidiato- 

 oblongo-ovatis, obtusis, spinoso- dentatis, margine dorsah 

 decurrente, basi recurvo, ventrali subcristato ; calyce ter- 

 minali, immerso, oblique, semirotundo, compresso, bine 

 basin usque fisso, inciso-ciliato.
