M u c h more common than the laft, growing in damp
fhady places, but the female fructification is rarely met with.
The feeds are perfected in March or April, and the plant is
perennial.
The fronds creep as in the other fpecies, and are of a darkifh
pellucid green, reticulated, bluntly lobed. Stalks from a cleft
between the lobes, long, flender, of a delicate texture, fo that
■with the tender conical head they look like fmall Agarics. The
head has five notches, and as many cells, each containing one
black capfule. The male flowers, as Hedwig with great probability
believes them, are borne on feparate plants in the
form of feflile warts towards the margin of the frond.
This fpecids is highly aromatic, and combines with fome
Jungermannus to give that fragrant odour to the air which is
perceived in grafiy walks under trees, near fountains, or among
damp fhady rocks, efpecially after rain. /%•)& JttShfJitd &y _/ Jjuttdy. Hr *•
