Exs. 206, 207. Metzgeria linearis, Moore Irish
Hepat. 666.
In moist situations.
PXXl.aXn..Xt.sZ 10 cc..mm.. lloonngg,, 2\ mm. broad, pallid,
yellowish, greenish, or lurid yellow, shining when
dry, very pellucid, dichotomous, linear, obtuse at
the’apex (plate 7, fig. 88), margins much reflexed,
nearly meeting, so as to make the stems appear
half-round when dry, subelliptic in transverse
section, hairs very long, in twos or threes together,
spreading widely, and arcuately bent.
This appears to be the M. furcata f3 elongata of
Hooker’s Jungermannise, pi. 56, fig. 2,
Metzgeria conjugata, Lind.
Autoicous, robust, rather elongated, more
or less dichotomous, or ir regular ly pinnate,
or decompound, linear, but nar rowe r in some
parts than in others ; antically convex, in
t ransverse section more or less semi-lunar ;
hairs longish, singly, or often in pairs on the
margin, and divergent.

The paucity of hairs and more horny substance
of the stems distinguish this from any of the normal
states of M. furcata, but the chief distinguishing
character seems to be the autoicous inflorescence,
which is remarkable in a genus where all the other
species are dioicous.
