JPLANT so minute as to resemble the filaments of a Conferva,
rather than the stems of a Jungermannia ; growing
loosely clustered. Roots consisting of a few small fibres, which
proceed in tufts from the underside of the stem and always
at the base of a stipule. Stems extremely slender, filiform,
rarely exceeding half an inch in length, generally much
smaller; and, as far as I have had the opportunity of observing,
undivided, of a brownish color when dry, exceedingly
fragile ; cellules small and oblong. Leaves throughout
the whole length of the plant rather distantly placed,
scarcely the eighth of a line long, patent or erect, of an exactly
cuneiform figure, the base decurrent; the apex entire,
or cut into a wide but very shallow notch; the margin every
where destitute of teeth or serratures. The cellules are
roundish; the texture, when dry, brittle; the colour in all the
specimens I have seen, a dull reddish olive or brown. Stipules
one to each pair of leaves, rather closely appressed
to the underside of the stem, small, of an ovate form, divided
