Dioicous ; densely cæspitose, blackish-green. Stems erect J— i J in.
high, dichotomous, fa stigiate-branched, w ith brown radic les among the
leaves. L e a v e s crowded, e recto-patent, multijugous, nearly equal, cu ltriform,

S e ta v ery short, terminal ; perich. b ra cts resembling the leaves, but
longer ; capsule small, erect, pachydermous, narrowly oval, olivaceous ;
lid conica l, obtuse ; te e th o f peristome e re c t, coa rsely a rticulated,

inflorescence, b ra c ts obovate, dilated, with a short sword-shaped lamina.

This interesting addition to our Flora has been found at the Rhine
Falls, and at Salzburg, and we have no doubt it is also the same as the
Californian F . ventricosus of Lesquereux. The capsules on our specimens are
old and without operculum, and we have completed the drawings of these
parts from Sullivant’s figures. Our plants grow associated with Cinclidotus,
those in the Rhine with Fiss. grandifrons, and the older leaves are generally
worn and abraded by the current.
