OF PACIFIC COAST MOSSES. 17 
104. O. Sturmii, Hoppe & Hrnsch. 
Hab. on shaded rocks, Yosemite Valley, Lol. 
105. O. Texanum, Sulliv. 
Hab. on rocks and trees, common in California, and extremely variable, Lol. 
Var. B. globosum, Lesqx. Capsula breviori, subglobosa, pedicello longiori emersa, 
calyptra colore nitente brunnea, caule breviori, foliis humiditate erectis. 
This form has a peculiar appearance, and seems, at first sight, a distinct species. 
But I do not find any good character to separate it. The peristome has either fuga- 
cious slender cilioli, or short incipient large ones, or none. A peculiar character of this 
species, and its varieties, which at once separates it from O. anomalum, is the black color 
of the spores. 
106. O. speciosum, Nees. 
Hab. on trees, Bol. ; Fort Colville, Lyall. 
Among the numerous varieties of this species, two forms, collected by Mr. Bo- 
lander, merit to be noted. 
1st var. polyanthum, Lesqx. Leete viride ; foliis caulinis laxe imbricatis, humiditate 
appressis, comalibus longioribus, floribus masculis pernumerosis. 
It has long slender branches, and a male bud in the axils of nearly each leaf. 
Hab. on rocks, Big Trees. 
2d var. brevicaule, Lesqx. Pallide vel luteo viride; cespitibus compactis, sicut 
pulvinatis ; caule brevi, theca terminali, pedicello longiori exserta. 
Hab. same as the former. 
M. Mitten quotes still 0. elegans, Schweer., (from British Columbia, Lyall) a 
variety less distinct from the typical form than both the above described ones. 
107. O. rupestre, Schl. 
Hab. on rocks, Big Trees, Lol. 
108. ©. rivulare, Turn. 
Hab. roots of elm trees and posts in water, Anderson Valley, ete., quite 
common, Bol. 
109. O. cylindrocarpum, Lesqx. Pusillum, monoicum subpulvinatum. Caulis sim- 
plex vel parce ramosus, obscure viridis, inferne nigrescens. Folia in sicco 
appressa, madefacta erecto appressa, e basi latiori elongato-lanceolata acuta 
vel subobtusa nervo valido cum apice evanido carinata, margine e basi fere 
usque ad apicem revoluta, areolatione ovato-quadrata minuta papillosa 
versus basim polygono-elongata. Folia pericheetialia vix longiora. Flos 
masculus in ramo proprio sub perichtio innovante, raro axillaris.  Capsula 
in pedicello brevi, exserta, cylindrica, vel cylindrica-ovalis, pallide viridis vel 
luteola. Peristomii dentes 16 per paria approximati, albidi ciliis 8 robustis, 
basi dilatatis «quilongis, duplici serie cellularum formatis, separati. Oper- 
culum conicum, margine rubellum vaginula calyptraque anguste conica 
plicata. valde pilose.
