 above, the upper lanceolate, the comal linear-lanceolate, up to 

 2,5 mm. long, long-acuminate at the serrulate apex, the margins 

 more or less recurved, the base non-decurrent ; costa strong, 

 reddish, ending below apex ; leaf-cells elongate-rhomboid-hexa-

 slender flexuous ; capsule horizontal to abruptly pendent, short. 

 1.5-2 cm. long, yellowish-brown, the short tapering neck darker

 mamillate ; annulus revoluble ; peristome rather short, teeth 

 linear-lanceolate, yellowish-pellucid, abruptly narrowed above 

 the middle to a sub-hyaline papillose apex, divisural and 

 lamellae present, trabecul?e strong, often a few connected by 

 oblique or vertical bars; segments of inner peristome a little 

 shorter than teeth, carinately split and gaping, cilia usually two. 

 sometimes one, articulate, shorter than segments : basal mem-
