p, 73.—Bill. Muse. t. 70. f. 15, 16.—,3. tridentata; leaves smaller
fewer with 3 sharp spiniform teeth at the extremity. J. tridenticulata,
Mich. Am. v. 2. p. 278.
Rocks in shady situations, especially in subalpine countries : yet Mr.
Li/ell finds it in the New Forest, Hants. /3. Mountains near Bantry,
Miss Hutchins. Scottish mountains. Fr. .—Though perianths
are by no means unfrequent on this plant, I am not aware that its perfect
fruit has ever been found in this country.
4. J. decijnens, Hook, {deceptive Jungermannia); stems erect
flexuose nearly simple, lower leaves small ovate entire upper
ones rotundato-ovate or subquadrate with here and there a
spiniform tooth. Hook. Br. Jung. t. 50. E. Bot. t. 2537.
Lindenb. Syn. Hepat. p. 73.
Rocks in heathy places, about Bantry, Miss Hutchins. Plentiful on
detached rocks in the woods near Killarney, Mr. Wilson; always barren.
— Mr. Wilson, to whom I am indebted, for numerous specimens, observes
that this is a good species, that the leaves have a thickened margin
omitted in the Brit. Jungermannhe, and the upper ones are appressed as
in J. compressa.
5. J. Bonidna, Hook. (Bonian Jungermannia); stem erect
subsimple flexuose, leaves closely imbricated patent oblongoovate
concave bidentate at the point frequently falcato-secund,
fruit terminal, perianth ovate laciniated. Hook. Br. Jung. t. 39.
E. Bot. t. 2566. Lindenb. Syn. Hep. p. 74.
Scottish mountains, rare; and almost wholly confined to moist rocks,
among other Jungermannice and Mosses, in the elevated parts of the
Clova and Cairngorm mountains. Dr. Greville has gathered it with
calyces, but these are of very rare occurrence, and the fruit of this most
distinct species is unknown.
6. J. ptimilfj, With, (dwarf simple Jungermannia); stem
ascending nearly simple, leaves elliptical oblong, fruit terminal,
perianth oblongo- ovate acuminate plicate and contracted above,
the mouth minute dentato-ciliate. With. Bot. Arr. ed. 3.

Rocky beds of rivulets, in subalpine countries. Fr. June.—A small
plant, with foliage of the colour and texture of./, cordifolia.
7. J. lanceoldta, Linn, (lance-leaved Jungermannia); stem
procumbent nearly simple, leaves patent ovato-subrotund, fruit
terminal, perianth oblong cylindrical depressed and plane at the
top, the mouth contracted inciso-dentate. Linn. Sp. PL p. 1597.
Hook. Br. Jung. t. 18. Lindenb. Syn. Hepat. p. 71.
Moist shady banks, and on the trunks of trees.
Light/out. Fr. .— Of this I have never seen
Hudson, Withering,
British specimens
and I suspect the authors just mentioned may have mistaken some other
species for it. It is remarkable for the cylindrical, and, as it were, truncated
summit of the perianth, and for the very minute contracted mouth.
8. J. cordifolia, Hook, (heart-leaved Jungermannia); stem
erect flexuose dichotomous, leaves erect concave cordate cir-
