This species is said to be closely related to O. tenellum, differ- 
ing in the shorter, less acuminate leaves, and the longer pedicel 
of the broader capsule. 
Type locality, on rocks, Dardanelles Cafion, Bolander. Also 
on the bark of Quercus agrifolia, without locality, Bolander. Con- 
sidering Sullivant’s tendency to refer distinct American species to 
European ones, and the diversity of these habitats, these specimens 
need further examination. The latter was distributed as No. 178 — 
of S. & L. Musci. Bor. Am. Ed. II. Also collected by Miss Martha 
R. Mann, “On live Oaks, at Monterey, Cal., February 12th, 
1886,” and by Marshall A. Howe, on trees at Berkeley, Cal., Oce 
tober, 1892. :

This species is allied to O. stramineum and O. Rogeri, differing 
from the first in the narrower, longer, flexuose leaves, twisted and 
slightly crispate when dry, the longer pedicel, the shorter hairs of : 
the vaginule, the teeth are more elongated, darker yellow, split, | 
not cribrose-lacerate at apex; and from the last, in the twisted : 
leaves, not excavate at base, and the capsule suddenly contracted 4 
below. On account of the crispate leaves, this moss has the facies 
- of an Ulota. : 
Type locality: On bushes, Coast Mountains, Oregon, L. F. bail? >

specimens are old, the peristome gone, and the calyptra is unknoW™ —
