TJnder the genus EJctropotJiecium it is proposed to arrange a 

 number of species hitherto referred to Ilypnum. All the species 

 are conspicuous for their regularity and closely pinnate prostrate 

 stems, which do not appear to become congested into tufts, but 

 to be always appressed to the surface on which they grow. The 

 foliage, as is usual in the extensive family of Mosses, of "whicb 

 this genus is but a small portion, is composed of leaves inserted 

 in ten different positions on the stem, each leaf having a distinct 

 form, and none of symmetrical outline but those which are in- 

 serted on the middle of the upperside of the stem. The cap- 

 sule is in all the species small, short, and without an attenuated 

 neck, perfectly pendulous when old, and supported upon a long 

 seta, curved only at its apex,
