I t is to be deeply regretted that, owing to ill-health and the
loss oi one of his eyes, this most acute and genial of naturalists
was compelled to relinquish working among the hepaticæ, for
there were few better qualified to carry on the work left unfinished
by the late Dr. Carrington.
I t will always be a pleasure to remember that his name is
associated with one of the gems of his Lakeland.
A remarkably distinct species, distinguished by its rosy purqjle
colour from most others ; tbe only one with which it can be confounded
being Eremonotus myriocnrpiis (Carr.), with which it agrees
in habit, and often grows with it. This species never has the purple
colour of II. Stableri, is furnished with numerous leafless stolons,
stem leaves are smaller, divided to the middle, bracts quadrate,
not broadly ovate, closely compiicate, always free, lobes obtusate,
entire, jierianth rounder, carinate, protruding beyond and quite
free from the bracts.
II. Stableri is distinguished from the small purple form of
Cephalozia dicaricata (Sm.) without stipules, by its more imbricate,
appressed leaves in its sterile state, and when fertile by its very
different perianth.
I he description is taken from Dr. Spruce’s contribution to
“ Eev. Bryol.” for 1881.

Dioicous, cæspitose, flagelliferous, small, pale green, here and
there with a slight reddish tinge, when dry a dull yellow colour.
Stems simple or slightly branched, flexuose, scorpioidal at the
apex, naked below, 12 cells in diam., cortical cells 24, rather
larger than the inner ; rootlets wanting or extremely sparse,
reddish-purple tinge. Leaves distant, alternate, small, scarcely
broader than the stem on sterile specimens, vaginate, upper ones
erect, roundish-ovate, lower erecto-patent, ovate, subquadrate,
oomqilicate-ooncave, rounded at the base, or subcordate, apex boatshaped,
to -J- acutely bidentate, lobes acnte, sinus acute ; cells
small, 4-, 5-, and 6-sided, walls moderately thick but weak, without
trigones in tlie British imperfect specimens, in perfect ones fully
developed trigones distinct. No stipules. Bracts larger than
the leaves, suborbicular to subquadrate, bifid to almost the middle,
segments acute, sinus acute. Perianth small, delicate, hidden in
the bracts, and adnate to about the middle to them, mouth
laciniate, sterile pistillidia surrounding base of calyptra. Androecia
terminal on main stem, 2, 3 pairs of leaves, imbrioate, roundish,
bifid to -J-, complicate, ventricose, enclosing 1 or 2 large, oval
antheridia.
