under the name of ‘“‘ Jg. excisa:’”’ these belong in nearly equal quan- 
tities to three species, viz. : 
1. J. ventricosa, forma minor = J. excisa, Hook. t. 9 (excl. 
var. 6). 
2. J. bicrenata, Lindbg. = J. excisa gemmifera, Hook. t. 
Suppl. 2. 
3. J. capitata, Hook. = J. excisa B. crispata, Hook. t. 9. 
ff. 2, 11, 12 = J. intermedia, Lindbg. 
It is exactly the same with specimens of “ Jg. excisa”’ from the 
continent of Europe, nor have I ever seen a specimen agreeing with 
the descriptions that have been given of this species. Hooker says 
of Jg. excisa, ‘ foliis profunde emarginatis ;” of Jg. ventricosa, “ foliis 
obtuse emarginatis :” Lindenberg says of Jg. excisa, ‘‘ Differt..... 
foliis minus profunde incisis :”’ lastly, the authors of ‘ Synopsis Hepa- 
ticarum” describe Jg. excisa, ‘‘ foliis . . . sinu profundo obtuso excisis.” 
From these and similar discrepancies, I cannot help concluding that 
these distinguished hepaticologists had under their eyes small forms 
of more than one of the three species above-cited when they drew up 
their descriptions of the supposed “‘Jg. ewcisa, Dicks.” Dr. Gottsche 
has even admitted to me that he is unable to determine Jg. excisa if 
given to him without a name. He adds, ‘ what I have received from 
my English and German friends under the name of Jg. excisa differ 
so much from each other, that I confess not to know the species.”

The leaves of this species are normally conduplicate ; the lowest 
unequally bidentate with diverging segments, as in many Scapanie ; 
the upper with very unequal lobes, the dorsal lobe triangular, undi- 
vided, appressed to the stem, the ventral lobe bifid: both either entire at 
the margins or with a few spinulose teeth. This is the typical struc- 
ture, but, very rarely, the dorsal lobe is also bifid, and sometimes the 
ventral lobe is not bifid, but cut at the margin into several unequal 
spinulose teeth: sometimes it is trifid. In all cases the complication 
is discernible, notwithstanding the thickness of the stem, and even 
when the lobes are squarrosely spreading (as is seen also in some 
true Scapanie, e. g. in varieties of S. nemorosa). Hooker’s figs. 3 
and 4, tab. 10, show this quite distinctly.

Obs. This very natural group, resembling Lophocolea in the nature 
of its fructification, may well constitute a separate genus, for which
