38. BARTRAMIA, Hedw. 

 Cespitose perennials, on the ground or rocks, innovating at the apex and branching 

 dichotomously or subverticillately ; stems erect, tomento.se. Leaves mostly dull 

 glaucous-green, lanceolate and often elongated from a subclasping base, papillose 

 both sides, serrate and costa excurrent ; areolation minutely quadrate above. In- 

 florescence various. Calyptra small, cucullate, smooth, fu^aceous. Capsule globose 

 or nearly so, usually cernuons on a long straight solitary pedicel (sometimes short 

 and curved), striate and sulcate when dry, with minute convex-conic operculum and 

 no annulus. Peristome rarely single or wanting, usually double as in Bri/um, the 

 inner teeth upon a short basal membraiu>, cleft to the base, segments at lengtli diver- 

 gent; ciIiola3 often present. Sporangium much smaller than the cavity, sti[)itate. 



A genus of nearly 100 species, largely Sontli American, rather sparingly rejjiesented in Europe 

 and North America. Besides the following, four other .species are found in the Atlantic States. 

 The section PItilonotis is letainetl as a genus by Schini])er.
