This very distinct species of Sagina, first discovered in Scotland by 

 the acute Mr. G. Don, has been for many years known as a native 

 of the coast of Ireland, where it was detected by my learned 

 friend R. Brown, Esq. In England,, too, it is not unfrequent. It is 

 of a reddish brown colour, perfectly glabrous and essentially distin- 

 guished from the two former species by the obtuse leaves, apetalous 

 flowers, and lengthened capsule.
