dry. Fructifications rare. Capsules small, red brown. Fruit-stalk short, 
white, rising- out of a toothed involucrum. Dill. Scales of the involu- 
crum cloven, membranous. Leaves when magnified cloven, not unlike 
those of J. curvifolia. GrifF. ( Leaves never undivided, as in the figure of 
E. Bot. Hook. E.) 
Silvery Alpine Jungermannia. E.) Wet rocks and by the side of 
rivulets on Cader Idris, Glyder and Snowdon, and the Highland moun¬ 
tains. Mr. Griffith. On rocks on the sides and tops of hills in Dart¬ 
moor, Devon. Mr. Newberry. P. Sept.—Oct. 
J. concinna'ta. (Stem erect, branched : leaves very closely imbricated, 
erect, concave, ovate, obtuse, emarginate: fruit terminal: calyx 
none. Hook. E.) 
(Hook. Jung. 3— E. Bot. 2229— FI. Dan. 1002, E.) 
Grows matted in tufts, reddish brown above, pale green below. Stalks a 
quarter of an inch high, very slender, brittle when dry, closely tiled with 
leaves, thickest at the ends. Leaves undistinguishable by the naked eye, 
smooth, membranous at the edge, always pressed to. Fruit-stalks ter¬ 
minal, short. Capsules brown. Lightf. Shoots compressed, but ob¬ 
scurely four-cornered. Scales of the involucrum, entire, rounded, which 
distinguishes it from J. julacea. GrifF. (with which it has very gene¬ 
rally been confounded both on the Continent and in Britain. E.) 
(Matted Jungermannia. E.) Rocks on the Highland mountains fre¬ 
quent. On Snowdon. Mr. Griffith. Sept.—Oct. 
J. rupes'tris. Shoots cylindrical: leafits awl-shaped, pointing one way. 
Dicks. H. S. — (E. Bot 1277. E.)— Dill. 73. 40. 
Whole plant very short, being about one-third of the length of a pin, 
blackish, upright, seldom branched. Linn. Shoots branched, dark 
green. Lecfits bent back. Involucrum cylindrical, not tiled as in J. al - 
pina. Web. Grows densely crowded together, short, naked below. 
Leaves very slender, reflexed, dark green, blackish when dry, pointing 
one way. Involucrum very minute, terminal, reddish, not scaly. Fruit- 
stalk very short. Capsules very small. Dill. 
(Dusky Rock Jungermannia. E.) On moist rocks on Snowdon and 
Glyder, Carnarvonshire; north of England, and Highland mountains. 
Plentifully upon rocks on the sides and tops of hills in Dartmoor, Devon. 
Mr. Newberry. P. March—Oct. 
J. trichophyl/la. (Stem creeping, irregularly branched: leaves 
imbricated on all sides, here and there fasciculated, setaceous, 
jointed, patent straight: fruit terminal: calyx oblong, the mouth 
contracted, ciliated. Hook. E.) 
(Hook. Jung. 7 — E. Bot. 2252. E.)— Schmid. 42. 1 to 23— Dill. 73. 37. 
Shoots only a few lines in length, closely surrounded by very slender leafits, 
of a pale yellow green. Fruit-stalk terminal. Involucrum long, cylin¬ 
drical, cloven. Weis. When magnified, the leafits appear divided quite 
down to the base into three or four awl-shaped segments, composed of 
globular joints. Fruit-stalk half an inch long. Capsiiles black. Leers. 
Leaves pale green, extremely slender. Branches numerous, irregular. 
Dill. (Hooker describes the joints of the leaves as a little longer than 
they are broad, and perfectly cylindrical/’ 1 E.)
