Boggy places and in springs, in subalpinc countries. Fr. .—The
capsules are unknown to me, and the perianths, which are very rare,
have been only found by Mr. Lyell in Angusshire, in August. The
leaves are peculiarly soft and flaccid, of a dark lurid green, almost black
when dry.
9. J. Spkdgni, Dicks. (Bog-Moss Jungermannia); stem procumbent
nearly simple (the gemmiferous elongations alone
stipuled), leaves orbicular, fruit terminal on short proper
branches, perianth oblong attenuated at each extremity, the
mouth contracted denticulate. Dicks. Cr. Fasc. 1. p. 6. t. 1.

Moist heathy places. Fr. Spring.—A very elegant and distinct species,
sending out large radicles from nearly the whole length of the
underside of its stem, by which it attaches itself to Sphagnum and other
mosses.
10. J. crenuldta, Sm. (crenulated Jungcrmannia); stem procumbent
branched, leaves orbicular margined frequently se-
(iind, fruit terminal, perianth obovate compressed 4-angled,
the mouth much contracted toothed. E. Bot. t. 14G3. Hook.
Br. Jung. t. 37. Lindenb. Syn, Hepat. p. 66.
Moist heaths. Fr. Apr.—Foliage anil perianth frequently tinged
with purple. The large cellules at the edge of the leaves that constitute
the margin which is so remarkable in this plant, are most observable,
as Mr. Wilson remarks, in those leaves which are nearest the
perianth.
11. J. gpliarocdrpa, Hook, (round-fruited Jungermannia);
-trni ascending simple. Leaves orbicular, fruit terminal, perianth
oblongO-OVate contracted and tubular at the mouth at Length
4-cleft, capsule (when dry) globose. Hook. Br. Jung. t. 74.

— According to Mr. Wilson's recent observations, this is a very variable
plant; whose perianth becomes Hid or deeply 5-toothed, onlj after the
emission of the capsule; and whose capsule seems to assume a Bphserica]
form almost in every case after having been dried.
12. J. hyaUna, Lyell, (transparent Jungermannia); Btems

fruit terminal, perianth oblong angulate, mouth contracted
