patulous coma, from a longly sheathing oblong glossy whitish thin base, 

 lineal-lanceolate, yellow-green or somewhat glaucous, when dry arcuato- 

 incurved, the wings more or less undulated, very concave, nerve stout, 

 terete, excurrent in a short mucro ; cells at base hyaline, small elongated 

 rectangular, slanting upward from the nerve to the margin, suddenly 

 joined by the oval chlorophyllose cells, which become rounded subquad- 

 rate toward apex. Perich. bracts similar, but a little more elongated, 

 caps, erect on a subflexuose seta which is yellowish above, purple at 

 base, leptodermous, oblong and oblongo-cylindraceous, pale yellow- 

 brown with a red mouth, lightly sulcate when dry ; lid conic-rostrate, 

 not annulate, teeth long filiform, equal, purple, on a narrow basal mem- 

 brane, erect or slightly twisted. Male plant simple or divided, bracts

Readily known by its soft texture and interruptedly comose leaves, with 

 their obliquely ascending basal cells ; in habit it comes nearest M. kumilis 

 (Hedw.), and the leaf also resembles that of M. incUnata so closely that it is 

 sometimes very difScult to decide between barren specimens.
