AutBsroicous. Plants rather densely caespitose, erect; bright green 

 above, reddish brown below. Stems of two kinds, i. fertile, having 

 leaves in 3 ranks, crowded, ovato-lanceolate, becoming 5 ranked and 

 enlarging into a coma ; 2. gonidiiferous, with leaves in 3 ranks, and 

 more distant, two in nearly opposite rows, the third smaller and 

 anterior, the gemmae lentiform, in a cuplike involucre of 4-5 reniform 

 leaves, terminating the stem. 



Fertile stem flexuose, i-i in. high, erect, simple or dichotomous, 

 radiculose at base, pale red. Lower leaves very small, remote, erect, 

 appressed, broadly lanceolate, rufous ; upper much larger, ovato- 

 lanceolate, patent, entire, nerve vanishing below the point ; peri- 

 chaetial bracts sheathing, lanceolate, elongated, rather obtuse. Cells 

 roundish hexagonal above, elongated rectangular at base. Capsule 

 erect, on a straight, smooth, purple pedicel, elongated, cylindric, 

 pale brown, with the mouth red ; calyptra reaching to middle of 

 capsule, whitish, rust colored at apex, mitriform, sublacerate at base, 

 irregularly plicate, with about 8 or 9 ridges, which run out into 

 serrate crests at apex ; annulus none ; operculum thin, conical, 

 straight or oblique; peristome of 4 erect, brown, pyramidal teeth, 

 connivent when moist, triquetrous, rigid, not articulated, but longi- 

 tudinally striate at back ; columella slender, cylindric ; spores very 

 small, smooth, green. Male inflorescence at the apex of special 

 shoots, which arise in pairs from a sterile female inflorescence; bracts 

 6-10, ovato-lanceolate, nerved. 



Gemmiferous stem with lax leaves, very small and distant below, 

 those about the middle being the largest, obovate, apiculate, with 

 the nerve vanishing below apex, then decreasing in size toward the
