386 NEW HEPAT1CJE. 



deflexed, rounded or very obtusely angular, slightly convex, 

 largely cellulose. The apex of the lobule lies adpressed upon 

 the leaf, but its base is involute and tumid. Perichsetial 

 leaves smaller than the cauline, erect, adpressed to the 

 slightly curved, slender base of the calyx. Tube of the calyx 

 curved, conspicuous. This species has the habit of the Euro- 

 pean Lejeunia serpyllifolia, Libert ; independently of its 

 generic difference, the plant is browner, and has larger and 

 more cordate stipules.

 acutis, involutis; stipulis rotundatis, integerrimis ; calyce

Hab. Bay of Islands, New Zealand. Dr. Sinclair, Hoot 



Herb. 



Tufts loose, dusky green or brownish. Stems about \ an 

 inch high, reticulated with large distinct cells. Perichsetial 

 leaves similar to the cauline, but larger. Calyx half-immersed, 

 having four wings, the two superior of which are the most 

 considerable. This, in many respects, strongly resembles 

 Lejeunia appianata, Nees ; the lobules of the leaves, however, 

 are more elongated and smaller, the cellules of the leaves are 

 larger, whilst the compressed calyx more properly comes 

 under the present genus. 



2. P. testudinea, Tayl.; caule laxe implexo, procumbente, 

 subramoso ; foliis arctius imbricatis, patenti-recurvis, ob- 

 longis, obtusissimis, integerrimis, margine reflexis ; lobulis 

 lanceolatis, involutis, subunidentatis ; stipulis minutis, 

 rotundis, integerrimis. 



Hab. On bark. Cincinnati, Ohio.
