 Hob. On shaded banks, and in deans, common. 



The largest and finest of our species. The leaves are often 

 only partially toothed, and not rarely quite entire. 



15. J". lanceolata^ stem creeping, prostrate, plane; leaves 2- 

 rowed, semi-amplexicaul, ovate, entire ; fruit terminal ; calyx ob- 

 long-pearshaped, cut. (tab. v. f. 14.) LIGHTF. Scot. 773. HOOK. 

 Scot. ii. 112. Dill. Muse. t. 70, f. 10. 



Hob. On shaded banks, amongst Jungermannia epiphylla and 

 Marchantia polymorpha, producing fruit in winter. 



This, in habit, comes near J. trichomanes, but the leaves are 

 greener, more dense in structure, and exstipulate. 



f- -j- -J- Leaves simple, the apex more or less cleft. 



16. J. emarginata, stem erect, slender, simple; leaves 2-rowed, 

 loosely imbricate, patent, obcordate, concave, emarginate. (Tab. 

 v. Fig. 15.) HOOK. Scot. ii. 112. 



Hob. Heathy deans, on moist rocks, in tufts of a dark red- 

 dish-brown colour. Longridge Dean. Rocks at Ord- 

 wheel. 



The stems are scarcely an inch in height ; the leaves brown, 

 and minutely areolar. The specimens of J. emarginata, /3. 

 preserved in MOUGEOT and NESTLER'S Stirpes Cryptogamce, 

 are larger in every way than ours, and of a lighter brown 

 colour; while those of J. Funckii are smaller, and the leaves, 

 perhaps, more deeply divided at the apex. In other re- 

 spects, the lattef" very closely resemble our specimens, but 

 the species is not a native of Britain. 



17. J. ventricosa, stem creeping, prostrate, somewhat branched ; 

 leaves 2-rowed, patent, square, concave, obtusely and broadly 

 emarginated ; fruit terminal ; calyx oblong, the mouth contract- 

 ed, plicated, toothed. (Tab. v. Fig. 16.) HOOK. Scot. ii. 1 13. ; 

 Loud. Encyclop. No. 14950. 



Hob. On heaths intermixed with lichens. 



The horns of the leaves are often tipt with a cluster of little
