Woods and shaded banks, in the North of England, Wales and Ire- 

 land. Not unfrequent in Scotland. Fr. June. — When seen under a 

 microscope, the margins and nerve of the leaf are of a deep blood colour 

 and the calyptra is of a red or orange hue. No one has studied this 

 groupe of Mosses more successfully than the Rev. Mr. Dalton of Croft, 

 and to him I am indebted for much information respecting the various 

 species of it. 



27. B. hornum, Schreb. (Swans-neck Thyme Thread-Moss); 

 stems elongated, leaves lanceolate acute reticulated their 

 margins thickened denticulate, nerve generally disappearing 

 below the summit, capsule oblongo-ovate pendulous, lid hemis- 

 phserical mucronulate. Schreb. Fl. Lips. p. 83. Turn. Muse.

Marshy places and in wet woods. Fr. Apr. — The whole plant is of 

 a lurid yellowish -green colour, the leaves very narrow, the lid hetni- 

 sphaerical with a short point. The perforation of the calyptra and its 

 adhesion to the seta below the capsule, as in Timmia cucullata, is a 

 common occurrence in this species. 



28. B. cuspiddtum, Schreb. (pointed-leaved Thyme Thread- 

 Moss'); stems elongated, leaves obovate acuminulate reticu- 

 lated their margins thickened denticulated in the upper half, 

 nerve running beyond the point, seta mostly solitary, capsule 

 ovate pendulous, lid conico-hemisphserical obtuse. Schreb. Fl.
