S e N T by Mr. Teefdale from Yorkfhire. It is not uncommon
in heathy places and moift groves, often adhering with its
long fhoots to the upper furface of Lichen caninus. In fuch a
fituation it however does not bloflom. When it grows in
patches on the damp ground, its branches are Ihorter and more
frequent, producing, about October and November, folitary
flower-ftalks from their fummits, bearing brown capfules. The
bafe of each ftalk is enveloped in a longifh tubular triangular
{heath, unequally lacerated at its orifice. This {heath, like the
whole herb, is of a pale or whitilh pellucid green, and of a granular
fubftance throughout. The leaves grow oppofite or alternate
; in, the flowering plants imbricated; in the barren ones
fcarcely fo. They are broad at the bafe, fomewhat decurrent j
at the fummit {harply two-lobed, the lobes generally unequal,,
and the notch between them rounded. Oppofite to every leaf
a fmall tuft grows from the Item, which looks like roots. W e
have been told that this fpecies was furniflied with laciniated
flipulae. Have thefe eluded our fearch ? or have thofe tufts of
roots been taken for them ?
This kind of Jungermannia is highly aromatic.
