Dioicous ; stems 3 8 in. long, crowded in soft olive-green fasciculate 

 tufts, rooting on stones and floating, the lower part setulose with the 

 persistent nerves of abraded leaves. Leaves elongato-lanc., decurrent, 

 obtuse or very shortly apiculate, unequal, subflexuose, patulous or 

 slightly secund, twisted when dry, subcarinate, slightly toothed at apex, 

 border thick rounded subterete, nerve thick, plane above, prominent at 

 back, excurrentinamucro ; basal cells small rectangular, upper hexagonal 

 opake. Fertile branches short, suberect, often secund, fruit immersed, 

 lower perich. bracts oblong-ovate, upper oblong, attenuate, subacute, the 

 nerve vanishing. Calyptra conico-cucullate, chartaceous ; caps, ovate- 

 oblong, leptodermous, sulcate when dry, fuscous ; lid conic, slightly 

 curved, half length of capsule; peristome purple, twisting to the right, 

 teeth from a narrow cancellated basal membrane, 16, each separating 

 into 2 3 filiform legs, anastomosing at base and adhering to the exserted 

 apex of columella. Male plants more slender, the infl. gemmiform, 

 collected into small clusters, bracts broadly ovate, concave, shortly 

 acuminate. 



HAB. Attached to stones or wood in streams, especially in limestone 

 districts ; not uncommon. Fr. 4 5. 



This genus stands between Tortulaceae and Grimmiaceae, and is usually 

 associated with the latter, but both in peristome and leaf-structure, its 

 affinity is clearly strongest with the former.
