quadrate-oblong, subcordate at the base, bifid to about the Jth,
segments obtusate, rarely subaoute, outer ones gradually becoming
smaller and changing into stem leaves. Perianth half hidden by

antheridia solitary, oval.

0^®- “ I r size this resembles Cephalozia divaricata, but its
true alliance is with Jung, minuta, of which it might be accounted
a microscopic form. Ovving to the rigid chitinous texture of
Jung, mgriocarpa, the stems and even perianths decay very slowly.
so that it is not uncommon to find five or six perianths, one above
another, representing the growths of so many seasons. This give
the plant a very characteristic appearance, when it is remembered
the shoots are rarely more than from 2 to 4 lines in length. The
same proliferous habit is not uncommon in .Tung, mimda, and it
shares with it other peculiarities, viz., the perianths were invariably
abortive and the pistillidia barren and undeveloped. The
young perianth looks like that of a Frullania; it is a point where
the crests meet.
From Jung, rigida, Lindb., which it also resembles in habit, it
may be known by its much smaller size, fasciculate ramification,
rapidly accrescent leaves, the lobes of which are equal, and the
different form of the perianth; whereas in Jung, rigida the shoots
are terete from the closely imbricated uniform leaves, the lobes of
which are unequal.” Dr. Carrington.
“ This curious little plant differs from J. laxifolia in the total
absence of stipules and the dense reticulation ; but in most other
respects it is a miniature counterpart of that species; and they
agree so perfectly in habit and in all essential characters that I
can hardly doubt they should stand in the same genus. I have
cut transverse sections of several perianths of J. mgriocarpa, and
have found them uniformly trigonous, with the third angle at the
back, as in J. laxifolia and in all Cephalozia. The furrow along
the middle of the upper face of the perianth, with a slight ridge
or keel on each side of it, quite corresponds to what is seen in
immature, or unfertilised perianths of several of the CephalozicB."
