12-14, large, pellucid, interior much smaller, subopaque. Leaves
small, subimbricate—in the sterile plant often distant—subascending,
rhomboid-rotund, antioally decurrent, bifid to about sinus
obtuse, rarely lunate, segments connivent, acute or subacuminate;
cells of moderate size, leptodermous, pellucid, slightly chlorophyllose,
quadrate-hexagonal, walls moderately thick, no trigones
or thickened angles. Stipules wanting. Inflorescence cladocarpous.
¥ terminal on very short postical branches. Bracts usually about
3 pairs, tristichous, the innermost considerably larger than the
leaves, delicate, oblong-rotnnd, bifid to the third, rarely trffid or
twice bifid, segments acutate, entire ; bracteole somewhat similar,
often connate with the bracts. Perianth linear-fusiform,when young
triplicate, when mature only towards the apex trigonous, mouth
subconstricted, denticulate or setulose (setse 1 or 2 cells long only),
carnose, towards the base composed of 3 layers of cells, in the
middle 2 and near the apex 1. Calyptra oval-globose, carnose,
almost the whole length composed of 8 layers of cells. Capsule
oblong-cylindrical, on a somewhat short pedicel. Spores of a
beautiful cinnamon colour, smooth. Elaters hispiral, slightly
darker in colour than the spores. Androeoia on short postical
branches, perigonial bracts smaller than the leaves, oval, to about
a third bifid, canaliculate-concave; antheridia solitary, oval, shortly
stipitate.

trunks, more rarely on sandstone rocks, often fruiting luxuriantly,
also on Sphagna and other bog mosses where it is usually sterile

Obs.—“ C. lunidafolia may be distinguished from C. bicuspidata
and connivens, and from most of their allies, by the dioicous
inflorescence ; the small leaves, obtusely cloven to only ^ of their
length, and rather more closely reticulate ; the bracts far less
deeply cloven, and rarely into more than two segments ; but,
above all, by the fleshy perianth and calgptra, the perianth being
3 cells thick below and 2 cells thick about the middle, and the
calyptra 3 cells thick almost up to the very apex : -whilst both these
organs in C. bicuspidata and connivens consist throughout of but a
single layer of cells. Moreover, the perianth is merely denticulate
at the mouth, while that of C. connivens has the almost unique
character, among European Cegjhaloeiæ, of terminating in long
cilia ; the perianth of C. catenulata being merely ciliolate, or setose
at the apex. The purple spores of C. bicuspidata afford an additional
mark of distinction from C. lunulæfolia!’ E. S.
In 1893 I received the iollowing interesting note from Dr.
Spruoe : “ In writing for a set of my hepaticæ, C. Delogne (who
has charge of the herbarium at the Brussels Bot. Garden) asked
for specimens of some of my British Cephalozia and Lejeuneoe, which
I sent him. I took the opportunity to ask if any specimens of
Dumortier’s hepaticæ were accessible. I t would seem that
Dumortier left uo herbarium of hepaticæ, and there are only a
few specimens from him in the national herbarium, where, however,
he occasionally worked and annotated some of the specimens.
When I was studying the Cephalozia I wished very much for a
