Muse. 53, 4 34 (1864). zi 
According to Sullivant 1. c. this species “ differs from O. Sturmu 
in the larger size of the plants, longer, more acuminate leaves and 
double peristome.” 
Type locality, “Texas, Wright; Santa Fé, New Mexico, Fend- 
ler.” Also California, Bolander, north to Vancouver and British 
Columbia, east to Idaho and Colorado. 
Var. globosum Lesq. Mem. Cal. Acad. 1: 17 (1868). 
We have a fragment of this variety from the type specimen, 
and have examined the capsules. They are short, immersed oF 
only partly exserted, globose pyriform, with a tapering neck, petl- 
stome single, teeth pale, smooth or with faint traces of thickenimg _ 
ridges as in O. dullatum, but not papillose. The spores are small, ‘ 
.o16-.018 mm., warty and brown and the calyptra sparsely hairy. — 
Our capsules are too young to show the ridges of the walls, the | 
cells being still full of chlorophyll, though the spores are ripe. ie = 
would seem as if the thickening of the teeth and the ridges of the — 
capsules were a later development. 
Type locality, « Nevada Falls, Yosemite, California, be 2 
der.” Also reported in Macoun’s Catalogue from Agassiz ae 
Yale, British Columbia ; specimens not seen.

Type locality, Napa Soda Springs, California, May, 1886, 
Martha R. Mann. A portion of the type specimen was sent ee 
by Miss Clara E. Cummings, in January, 1891, with a copy of the 
original description. They agree, but the stomata are N° 
mentioned. They are superficial around the middle of the ¢4P 
sules ; nor the spores, which are rough with warts, and .O13—*" 
mm.; the cells around the mouth are densely thickened, with 
projecting annulus; the teeth are slender and thickened 
coarse sinuous ridges, and the plants are 5 cm. high and
