BRITISH HEPATIC^. 17 



On comparison with an original specimen of Sa/r. piceus, De Not., I find it iden- 

 tical with Sar, alpinus, Gottsche. The name therefore should be Na/rdia picea. I hope 

 to give a more detailed description and figure in a later part. 



Another form (Ravine of Janira, Forfar, A. Groall) resembles y minor in 

 size, but is more densely tufted, compressed, and erect ; the leaves are nearly uniform) 

 of a dull green, sometimes sphacelate at the apex. The upper part of the leaf 

 resembles N'. sphacelaia, but it wants the vaginate base. 



Sarcoscy. Ehrha/rti S saccata, N. ab E., is only the male plant of Jf. ema/rginata. 



No. 255, G. & E. Hep. Eur. (Silesia, Hibe), with the upper fig. 7. major viridis, 

 belong to N. sphacelaia.

Pl. II. Fig. 6 {ex parte). 



Densely caespitose ; stems very short, erect, rigid, fastigiately 

 innovant ; leaves approximate, erecto-patent when moist, erect 

 when dry, sub-rotund, carinate-concave, acutely emarginate, lobes 

 acute ; involucral leaves much larger ; involucre ovate, lower half 

 connate, acutely bilobed, the segments incurved ; 2 to 4 lines.

3 robustior. Shoots compressed, stouter ; leaves approximate, 

 twice the breadth of the stem, elliptic-obovate, complicate ; lobes 

 inflexed, dark-brown, polished, 2 to 6 lines. 



/3* diffusa. Stems longer, intricately and repeatedly innovant, 

 fastigiate ; leaves more remote, sub-vertically patent, not unfre- 

 quently sub-secund, lobes divergent ; reddish-brown or dark-brown, 

 polished ; -J in. to 1 in. 



Hab. Forming extensive (for the size of the plant) dark brown or nearly black 

 patches on shady siliceous or argillaceous rocks, in habit resembling the rigid form 

 of J. diva/ricata. Tilgate Forest, Apr. 1858, G. Davis I Black Mountains, Ireland,
