 the coma! and perichaetial leaves incrassate, elongate to linear-prosenchyma- 

 tous, about .008-. Oil x .040-. 065 mm, towards the margin gradually narrower

 inflorescence paroicous, terminal; antheridia in the axils of the comal leaves: 

 pedicel solitary, slender, lustrous, castaneous, erect, flexuous, about 4-6 cm 

 high; capsule horizontal to sub-pendulous, smooth, castaneous to yellowish- 

 brown, ovate-oblong, often very slightly curved, 2.5-3.5 mm long, when dry
