alpestris, Schleich., but specimens of the latter from Dr. Gottsche 

 differ in having the leaves roundish-ovate (not quadrate as in Jg. ven- 

 tricosa), the sinus small, and the segments unequal, oblique. 



Var. minor. " J^. excisa, Dicks. ? var. foliis e basi cuneata 

 ovato-quadratis obovatisve, marginibus inflexis, sinu triangulari 

 lunatove, involucralibus bifidis, integerrimis ; perianthio oblongo, 

 ore obtuse plicato •" H. P. 32. 



I believe I am correct in regarding this a minute form of Jg. ven- 

 tricosa ; the leaves are usually more deeply cloven, the sinus trian- 

 gular, the segments often divaricating ; and yet stems of the large, 

 ordinary form may be found having the same characters.

I am quite of opinion that the original name of Hooker should be 

 retained for this species. Lindenberg was evidently not aware that 

 his own Jg. intermedia and Hooker's Jg. capitata were forms of one 

 species ; from his description it is probable that he did not clearly 

 distinguish it from some forms of his Jg. hicrenata, as he cites for it 

 Hooker's tab. Suppl. 2 (Synopsis, p. 1 1), which exactly resembles 

 Ekart's figures of Jg. bicrenata, and agrees well with specimens of 

 the gemmiferous state of that species in my possession.

Dr. Gottsche has pointed out to me the remarkable scent of this 

 species, resembling that of Jg. acuta and Bantriensis, and quite want- 

 ing in Jg. capitata ; by this character, by the deeply and acutely 

 cloven leaves, and especially by the guttulate areolation, Jg. bicrenata 

 may always be safely distinguished. 



I fear Jg. excisa, Dicks. Crypt. 3. p. 11. t. 8. f. 7, will have to be 

 entirely erased from the list of Hepaticse. I have spent much 

 time in the attempt to ascertain what it really is, but without suc- 

 cess ; formerly I thought it might be Jg. bicrenata, especially as there 

 is a rude attempt in Dickson's figure to represent the guttulate areo- 

 lation, characteristic of that species ; but the larger size, the branched 

 stem, and especially the narrow shallow sinus of the leaves, seem to dis- 

 prove such a supposition. Very lately I consulted the Smithian her- 

 barium in the hope of finding an original specimen from Dickson, 

 but even the name does not seem to exist there. I have examined 

 a multitude of specimens from various parts of the British Isles, sent
