NEW HEPATICLE. 259 



clavato-rotundate at their tops, which are twice as wide as 

 the inferior part of the shoot. Pericheetial leaves more im- 

 bricated, more concave and rounder than the cauline; 

 within the perichatium was found a pair of minute whitish, 

 scariose, very connivent scales, but neither calyptra or barren 

 pistilla were present.

 flexuoso, apice incurvo, subramoso ; foliis arete imbricatis,

Tufts wide, olive-brown. Stems 5 inches high, prolonged 

 by one or two annual branches. Leaves, even when moist- 

 ened, secund, more erect than patent, the inferior portion 

 gibbous and more strongly ciliated. Pericheetial leaves 

 similar to, but larger than the cauline. Calyx obovate, 

 truncate, compressed before flowering and, contrary to what 

 is common in the genus, less strongly ciliated than the leaves. 

 This species is far a larger plant than P. biserialis, Lind., its 

 leaves are by no means decurrent, and the calyx is dentate, 

 not subentire.

Tufts loose, pale olive green. Stems 2-3 inches high, 

 several from the same point, hence appearing fascicled ; shoots 

 S1 mple, very slightly curved. Leaves scarcely imbricated,
