Sueo. n. 191) is certainly this variety, being a large form with
stipules. Dr. Spruce observes that .Tmg. banfriends, when young,
has perianth pyriform or broadly clavate, hut var. Muelleri,
cylindrical.
■Tung, bantriensis has often the sinus folded at the base, var.
Muelleri usually plane, but I find the type and var. with and
without this feature. Nees describes Jung. Muelleri with bracts
dentate ; I should think he liad some other species under his notice,
for I have seen no approach, in anj' form, to this character.
Forms of Jung, ventricosa, Dicks., have been confounded with
this variety, but are recognised by the postical side of the stem
being coloured violet, the absence of stipules, the presence of
bracteole, which is connate, the bracts and the ovate perianth.
Distinguished i'rom Jung, bantriensis, var. acuta, by the presence
of stipules, &c.

Dioicous, cæspitose, small, pale or dark green to brown in
colour. Stems decumbent or suberect, simple or innovantly
branched, branches delicate, arising from base of perianth or apex
of old stems ; radiculose, rootlets white, copious, ascending to
apex of stems. Leaves approximate or distant, somewhat secund
or repand, semi-vertically inserted, slightly ascending, antical base
a little decurrent, ovate, oval or orbicular, bifid to about J,, sinus
narrow, obtuse or acute, segments acute or sometimes obtuse,
margin entire; texture lax, cells roundish-quadrate, sometimes
elongate, walls thick, trigones distinct. No stipules. Sub-bracts
similar to leaves, slightly larger. Bracts larger, oval, ovate or
subrotnnd, bifid to about I, sinus obtuse or acute, segments obtuse
or acute, margin entire or sometimes with a very slight antioal
indentation. Perianth jwojeoting about f beyond the bracts,
cylindrical or oblong-obovate, smooth, mouth small, slightly
dentate.
Male stems delicate, bracts more erect, clasping the stem, oval,
complicate, saccate at the base, bifid, with usually an antical
segment, antheridia single, oval.

O b s .—This form difi'ers from the type by its smaller size,
absence of stipules ; from var. Muelleri by the absence of stipules ;■
from Jungermania turbinata, .Eaddi, bj' the shaj e and te.xture of its
leaves, the sub-bracts and bracts being rarely distinctly antically
notched, the perianth not turbinate.
