3. LEPTOBRYUM Wils. 



Bry. brit. 219 (1855). 



Plants annual, innovating only at base, slender simple. Leaves 

 narrow, flexuoso-subulate with a broad nerve, cells lax rectangulo- 

 hexagonal at base, above linear-rhomboid. Calyptra narrow, cucullate. 

 Capsule pendulous, leptodermous, long-necked, vernicose, peristome 

 bryoid. Der. Xetttos slender, fipvov a moss. 



A small genus of 3 species, another — L. tenuinerve Spruce — coming from 

 the Andes, and the third L. robustum from Australia. Its mode of growth and 

 general habit alone separate it from Pohlia.
