Jung. Doniana. Mr. Wilson observes that it yields a fetid
stnell like that of Castor.
The stems, which are 4—5 inches long, and simple or
slightly branched, grow loosely tufted, and often mixed with
other Jungermanniae and with mosses. The leaves are closely
placed, bifarious, vertical, cut to the very base into 2 unequal
conduplicate appressed and flat lobes, so deeply indeed that
they might with more propriety be considered two distinct
leaves instead of lobes, the longer ones inferior and imbricating
the lower side of the stem, ovate, and horizontally
patent; the upper ones obliquely imbricated, cordate; all
of them of a deep purplish brown colour, plane, marked with
close reticulations, and beautifully fringed with tooth-like
cilia at the margin. The fruit is wholly unknown to us.
In habit the present species will rank assuredly near
J . nemorosa, but may be at once known from it by a much
greater size, more rigid texture, deep purple colour, and
above all by the separation, if I may so speak, between the
upper and lower lobes of the leaf; so that the upper or
lesser lobe has all the character of a stipule.
The specimens here figured were kindly communicated
by W. Wilson, Esq., from Brandon, Ireland.—W. J . H.
