    less readily be confounded with Fontinalis antipyretica, which grows almost in all running waters, but is distinguished by its triple direction, by its want of nerves, and by the some- what keel-shaped nature of its leaves, which are also much larger, and more remote. The capsules are enveloped: by short round scales-: the. peristome consists in a trellis- shaped net. The other aquatic mosses are still less similar. Hypnum fluitans L. is distinguished by very small leaves, separate from one another and alternating; by long fruit- stalks, and by a double peristome ; H. ruscifoliwm Neck. by its ovate, serrated leaves, the nerves of which extend almost to the point, by its long petiolated nodding capsules; AH. ri- parium, by the fibres which every where proceed from the axillz of the leaves; H. fluviatile Hedw. almost solely by its petiolated capsules with a double peristome. ~ The genus Cinclidotus, first estabished by Palisot-Beau- vois, and admitted by Hooker, stands between T'richostomum and Barbula, From the former, with which this moss used to be classed, it is distinguished by having the teeth of the pe- ristome united below, and twisted above. Barbula is distin- guished by this circumstance, namely, that the twisted cilia of the peristome are tender, and must be considered merely as prolongations of the internal membrane of the capsule. The calyptre, too, is laterally divided. Synonymes and Figures. Fontinalis minor lucens, J. Bauh. Hist..3. 170. Foliis ‘tr’: angularibus minus complicatis, Rai Syn. p. 79.
