This plant is subject to vary greatly in its general appear- 

 ance, in size, and somewhat in the shape and direction of 

 its leaves. Its stems are erect, pinnate, frequently with 

 downy ferruginous roots; and the stems themselves and 

 nerves of the leaves are reddish brown. The cauline leaves 

 are the shortest and broadest, with the nerve excurrent, 

 which is characteristic of the species, and, together with the 

 less falcate foliage, distinguishes it from H. commutatum, 

 notwithstanding that Sehwaegrichen has lately united them. 

 The large variety, growing in running water, is the H*fal- 

 lax of English Botany, and probably also of Bridel. But 

 this again Sehwaegrichen has joined to H.Jluviatile, a plant 

 we believe unknown to Britain, and appearing, as far as we 

 can judge from the figure in the Species Muscorum, very un- 

 like H.fallajc. H.falcatum of Bridel likewise seems, from 

 the author's description, scarcely different from our plant, 

 which, when growing in waters impregnated with calcareous 

 matter, is seen to have the stems bristly at the base, from 

 the strong nerves that remain after the decay of the rest of 

 the leaf. 



60. H. atro-virens\ stems variously branched, procumbent; 

 leaves, all of them, slightly secund, broadly ovate, with an 

 attenuated obtuse point, nerve running nearly to the sum- 

 mit j capsule ovate, cernuous 5 lid conical. (TAB. XXVI.)
