(Wood Jungermannia. E.) Woods and moist shady places in West¬ 
moreland. (Pentland Hills. Greville. E.) P. March—April. 
J. resupinata. Shoots doubly winged above : leafits finely scolloped, 
tiled, circular. 
(Hook . Jung. 23. E.) 
( Plant pale green. Stems not an inch long, procumbent, except the 
fructified extremities. Leaves spreading, the lobes nearly equal, except 
in the lower ones, where the upper lobes are smallest, margin entire. 
Peduncle nearly half an inch long. Calyx compressed at the mouth, 
incurved, and minutely denticulate. Grev. Much smaller than J. undulala. 
Hook. E.) 
(Reclining Jungermannia. E.) In clefts of rocks, and on turfy heaths. 
P. April. 
J. ai/bicans. (Stem erect, subdivided: leaves unequally two-lobed, 
lobes conduplicate, with a pellucid line in the middle, serrated 
at the extremity; lower ones larger, sub-cymitar-shaped; upper 
ones oblong-ovate, acute: fruit terminal: calyx obovate, cylin¬ 
drical ; the mouth contracted, toothed. Hook. E.) 
{Hook. Jung. 25— E. Bot. 2240. E.)— Dill. 71. 20— Vaill. 19. 5. 
Shoots one to two inches long, not creeping, but reclining. Weis. Form¬ 
ing dense patches, one shoot lying on another. Leafits two-rowed, half 
a line long, and a quarter broad, very entire; ending in a blunt point. 
Besides these larger leaves, there is another set only half the size on the ‘ 
upper side of the mid-rib, one at the base of each larger leaf. Involu - 
crum cylindrical, white, terminal. Barren stems reddish at the ends, and 
containing minute greenish globules filled with a powder. Poll. Whitish 
when dry. Dill. 
(Whitening Jungermannia. Under this species Hooker includes 
J. varia. E.) Woods and wet shady places. P. March—April. 
J. cochlearifor'mis. Somewhat cylindrical, rather upright: leafits 
concave, roundish. 
Hook. Jung. 21, f 16— E. Bot. 2500. E.)— Dill. 69. 1— Mich. 5. 16, hut 
more evidently fringed than in our plants. 
Leafits pointing from two opposite lines, nearly egg-shaped, transparent, 
smooth, embracing the stem, pointed, each furnished with a very small 
earlike appendage. I have never seen any other than barren plants. Linn. 
Stems hollow, reddish. Scop. Shoots creeping, strap-shaped, the ends 
rising upwards. Ijeafits about a line in diameter, flat. Poll. Varies 
greatly in appearance. The young plants in wet places crowded, up¬ 
right. leaves very small, roundish, nearly flat, pellucid, alternate, with¬ 
out appendages. When older, the leaves are large, more closely set, con¬ 
vexo-concave, with scaly appendages at the base, resembling the leaves 
in shape. In some plants, when fully grown, the leaves are roundish; 
in others spoon-shaped; and in another variety, gathered on the banks of 
mountain lakes, I have found the leaves green, pellucid, not crowded, 
almost embracing the stem. Shoots sometimes branched, from one inch to 
a foot long when growing in running water. Have not found it in flower. 
Dill. Have frequently found it with fertile heads. Huds. I have found 
the capsule filled with ripe seeds, but closely enveloped by the leaves 
at the extremity of the plant, and probably never rising above them.
