( .] . stipulacea .) 
BRITISH JUNGERMANNIiE 
Perichcetial leaves small: two or three of them surround the base of the calyx. Each 
is roundish, and cut into three unequal and acute segments at the extremity. 
Male Fructification unknown. 
Female Fructification (f. 5) lateral; at least, it is so in the only fertile specimen that 
lias come under my notice. 
The Calyx (f. f. 9. 10) is ohovate, of the same color and texture as the leaves, slightly 
plicate towards the extremity, where it is a little attenuated. The mouth is con- 
tracted, plicate, obtusely toothed. 
The Calyptra (f. 10) appears to be equal in width, and even to adhere to the sides 
of the calyx, of which it is about three-fourths of the length ; the upper part only 
is detached, and is membranous, whitish, and reticulated. 
Peduncle two or three lines long, white, cellulose. 
Capsule ovate, deep brown, striated longitudinally and transversely. 
Seeds and spiral filaments (f. 11) reddish-brown; the former spherical, the latter formed 
of a double helix. 
This little species has been detected both in Ireland and in Scotland. Its minute size 
may have caused it to be overlooked in other parts of the kingdom, but this peculiarity, 
together with its large stipules, and the prominent situation of these, and their figure, afford 
striking characters; though, in the latter particular, it very nearly corresponds with another 
new species ( J . Bantricnsis, mss.) which has lately been discovered by Miss Hutchins, and 
which has, like the present, emarginate leaves : but it differs in its much greater dimen- 
sions, in the less concave, obtusely and slightly emarginate leaves, in the small stipules, and 
in the situation of the calyx, rising quite leafless at the base from the upper side of the 
stem, as that of J. pusilla does. I must here mention another species, found in Scotland by 
Mr. Lyell, which has considerable affinity with the present in the size of the stipules, and 
still more so in their form : but, besides that its leaves are twice or thrice as large as those 
of J. stipulacea, they afford a more decisive character in their obtuse segments. With the 
two plants now mentioned, J. stipulacea will undoubtedly range. They all differ from J. bidentata 
and J. heterophylla, in having entire stipules ; while these have them deeply divided.
