History, Use, Propagation, Culture^ 
rally covered by a very hairy calyptra : this organ is in some species smooth, by which character they have been 
distinguished by the accurate Ehrhart, under the name of Catharinea ; but Dr. Hooker is of opinion that the 
genus is not tenable. , . ,i x c iu- *i 
2242. Anictangium. From otmxTos, open, and u.yymv, a vase, on account of the open nature ot the tneca, 
which is not enclosed by a peristome. The only British species are two plants with nerveless leaves, and the 
habit of Trichostomum. „ , . ^ to * 
2243 Fissidens. From Jissus, split, and dens, a tooth, in allusion to the structure of the peristome, /lams 
generally referred to Dicranum by British botanists, but differing from that genus entirely in habit, and sutti- 
ciently in characters. Dr. Hooker remarks, that the structure of their leaves is highly curious, and totally 
unlike that of any other plant with which he is acquainted. Besides being vertical, their upper half taking 
the nerve for the line of separation) is, from the base beyond the middle, composed of two equal lamellae, the 
lower part of which embraces the stem, and the rest very often embraces a portion of the leaf placed imme- 
^^fi^.^Leucodon. Named from Xwxof, white, and odus, a tooth, from the color of the peristome. The only 
British species has occasionally been thrown among the Dicrana, Trichostoma, and Pterogonia ; from any of 
which, an attentive consideration of the lateral fruit, deeply divided teeth, and dimidiate calyptra, will keep 
its genus distinct. The stems are long, and creeping over the bark of trees. , 
2245 Fontinalis. From fons, a fountain, in allusion to the places where it grows. F. antipyretica is a 
common plant, floating in large masses in rivers and pools of water. The specific nam^ was given it because
