1084 CRYPTOGAMIA. HEPATIC-®. Jungermannia. 
On the bottom of trunks of trees among- moss. At Callington, near Edin¬ 
burgh. Mr. Brown. P. April-—May. ll.) 
J. sinua'ta. Frond doubly wing-cleft, flat, indented, open, ending in 
two unequal lobes. Dicks, ii. 16*. 
{Hook. Jung. 45— E. Bot. 1476. E.)— Hill. 74. 44— Mich. 4. 8. 
Leaves permanent deep green, thin, pellucid, flat, cut into winged seg¬ 
ments. Dill. Leaves lying one upon another, in which way it appears to 
increase till it has covered a large patch of rock. (When moist and first 
gathered, it exhales a fine aromatic scent, which, uniting with the fra¬ 
grance of certain Mosses, imparts to the air a peculiar and refreshing 
odour, often perceptible from grassy walks under trees or shadowy 
rocks, especially after showers. Prof. Hooker perceives no difference 
between this plant and J. multifida , except that the frond is somewhat 
wider, and the divisions frequently, but by no means constantly, so short 
that the margins appear to be here and there sinuate, rather than cut 
into segments. E.)
