Heaths, rocks, walls, &c. Fr. May. — Readily distinguished from the 

 following by its obovate leaves, twisted when dry, their nerve extended 

 into a longhair-like point, and by the greater length of its capsule. 



15. B. ccespititium, Linn, (lesser matted Thread-Moss); stems 

 short, leaves ovate acuminated entire or very obscurely serrated 

 at the points their margins slightly recurved, the nerve reaching 

 to or beyond the point, capsule ovali-pyriform pendulous.

Banks, walls and roofs of houses, very frequent. Fr. May. — That 

 this most common of mosses is very variable, every one will allow, who 

 has been accustomed to examine it in different situations, and under 

 different circumstances : and the German Botanists, especially, seem to 

 me to have unnecessarily raised these varieties into species. These 

 have been mentioned in the Miucologia Britannica. I had, indeed, 

 there, though with a mark of doubt, included the B. Wahlenbergii of 

 Molir, (B. albicans, Wahl.): but that plant I am now disposed to keep 

 distinct and to place near B. carneum. 



16. B. turbindtum, S\v. (turbinate Thread-Moss); stems short 

 branched with innovations, leaves ovate acuminate nearly en- 

 tire their margins slightly recurved, the nerve running beyond 

 the points, capsule elongato-pyriform pendulous. Swartz,
