Stems densely casspitose, from two to four inches, and
more in length; below generally decumbent and
simple, with numerous downy radicles, blackish ;
above erect* branched, deep green.
Leaves numerous, loosely imbricated, erecto-patent
oblongo-lingulate, very obtuse, entire, somewhat
undulated, reticulated with oblong areolm, furnished
with a nerve of the same colour which
disappears below the apex; the lower ones, as

Fruitstalk terminal, erect, flexuose, smooth, deep red.
Capsule erect, brown, and (together with the obconical
apophysis which is of the same colour) almost
entirely pyriform, contracted a little below the

Calyptra a t first always mitriform or entire, at length
cleft on one side, and then dimidiate.
Lid shortly conical, subacuminate, yellow-brown, not
unfrequently adnate with the columella.
Peristome : Teeth sixteen, equidistant, lanceolato-

marked with a central longitudinal line and transversely

Seeds numerous, yellow-green, spherical, appearing un-
