Dioicous, loosely cæsjiitose, medium size, pale green to fusce-
scent in colour. Stem simple or bifurcate, thick, succulent, fragile,
flexuose, below pale brown, above dark or pale green, on the
postical side more or less brownish, prostrate, apex slightly-
ascending, the whole postical side densely radiculose ; rootlets
short or long, often in fascicles, near the base purplish-brown,
near apex liyaline. Leaves on sterile stems usually decrescent,
sometimes of equal size, somewhat remote, upper often closer and
contiguous, somewhat concave, obliquely inserted, slightfy decnr-
rent antically, rotund to obovato-quadrate, to ^ or a little more
bilobed, sinus semi-lunate, broad, gibbous, obtuse, rarely acute
and narrow ; lobes oval, obtuse or rotundate, sometimes somewhat
acute, slightly unequal, postical usually larger ; texture tender
and soft ; cells smallish to medium in size, somewhat dense,
quadrate-rotundate, more or less chlorophyllose but often translucent;
angles slightly thickened; cuticule verruclose. Stipules
usually absent, when present rudimentary, more frequent on tbe
male stems and at the apex and fork of bifurcate stems, minute.
subulate-lanceolate. Bracts similar in size to the leaves, or rather
smaller, irregularly 2-4-lobed. Bracteole variable, entire or bifid.
Perianth qrrojeoting, pale green, cylindrioal-obovate, upper -J- pluriplioate,
below smooth, composed of one layer of cells, mouth
narrow, hyaline, irregularly ciliolate, with 15-20 cilioles, 1 and 2
cells long. Male plant more slender ; androecia 3 to 4 pairs at
the middle or apex of stem ; perigonial bracts much smaller than
the leaves, concave, at the base saccate, bilobed ; lobes obtuse,
connivent, unequal, postical larger;, sinus broad, obtuse. Antheridia
1-3 in each bract, oval-globose, yellowish-green, stipitate.

PIab.— On rocky ledges, in alpine situations. Ben Gaire,
1700 ft,, Moidart, West Inverness, Sgmers M. Alacvicar, July 27,
1898.
The only known British station. Pound in Norway, Switzerland
and Styria.
O b s .—There is no other alpine hepatic which this species
is likely to be mistaken for, the obtuse lobes of the leaves readily
distinguishing it.
Drs. Kaalaas and Jorgensen have confirmed the Scotch specimens
and have also sent me a series of Norwegian specimens with
which our species fully agrees.
The figure given by Dr. Henri Bernet in his “ Cat. Hep. Sud-
Ouest Suisse ” does not well agree with any specimens I have seen.
■Tung, obtusa is one of the numerous discoveries made in Scotland
by my friend Mr. Macvicar.
