Tufts flat, thick, brownish-olive. Stems from one to two 
inches long. Leaves somewhat recurved, when dry they 
appear to have at the base, and near to the stem, each an 
oval body, which in realityis the swollen base of the recurved 
lower lobe, whose rounded summit, however, lies flatly ad- 
pressed to the upper lobe. From under the leaves several 
annual shoots arise like the stem, but diminutive in all their 
dimensions; with these frequently alternate very minute 
filiform perigonia, having eight or ten pairs of pitcher -shaped ——— 
closely imbricated leaves; the entire perigonia are cove 
by the upper lobe of the leaves. The pericheetium is formed 
of two erect leaves, whose tops are wide and round, and 
whose inferior lobes overlapping each other form almost a 
tubular base. : 
This species is closely allied to Radula pectinata, of Nees ; 
but the leaves of this have their upper lobes more elonga 
while the lower terminates in a single broad tooth or apicuus; — 
the perigonia, too, are shorter in proportion to the leaf. The AR 
calyx is singular in the present species for having, on each - 
side, from four to five elevated opaque ridges or wings.
