its almost constant companion in tlae Pyrenees; in the S. W. of Ire- 

 land; at Tunhridge Wells in England; at Loch Lomond, Glen Finnan, &c., 

 in Scotland. In the British Isles G. curvifoUa abounds most at Killar- 

 ney, and would seem rather rare in the North of England ; where how- 

 ever it has been gathered by G. Stablee near Whitby, and in Naddle 

 Forest (Westmorland); and by J. Nowell near Todmorden. In North 

 America it extends as far south as Mexico. It has been found also in 

 the Azores, and even (according to the authors of ' Syn. Hep' J in South 

 Africa. 



This is doubtless one of the most beautiful of all hepaticse, not only from the ele- 

 gance and singularitj' of its form, but from its showy colours of white, rose and purple, 

 assuming a gr^en or olive tint only in deep moist shade ; yet it has no character which 

 is not shared by other true Gcphalozice beyond the inflesed auricle, or lobule, on the 

 lower side of the leaf, and this quite disappears in the involucral leaves, of both male 

 and female flowers, and even sometimes in the ordinary leaves towards the apex of 

 drawn-out stems and branches. — C. Lammersii has often been mistaken for it, and 

 some even of Hooker's figures have probably been taken from an intermixed plant of 

 that species, although the two are widely different, as may be seen from compar- 

 ing the descriptions here given. Both Gottsche and Carrington have noted the 

 occasional bifurcation of the stem in C. curvifoUa, with a difform (unicrural) leaf at 

 the fork. It is a very rare feature, but I have seen it also in G. tubulata, C. argentea, 

 and two or three others, and it may possibly occur occasionally in every species of the 

 genus.
