OF PACIFIC COAST MOSSES. IT 



104. O. Sturmii, Hoppe & Hrnsch. 



Hab. on shaded rocks. Yosemite Valley, Bol. 



105. O. Texanum, Sulliv. 



Hab. on rocks and trees, common in California, and extremely variable, Bol. 



Var. B. globosum, Lesqx. Capsula breviori, subglobosa, pedicello longiori emersa, 

 calyptra colore nitente brunnea, caule breviori, folds 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 0. anomalum, is the black color 

 of the spores. 

 10G. O. speciosirm, Xees. 



Hab. on trees. Bol. ; Fort Colville, Lyafl. 



Among the numerous varieties of this species, two forms, collected by Mr. Bo- 

 lander, merit to be noted. 



1st var. polyanfhum, Lesqx. Lsete 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 ; crespitibus compactis, sicut 

 pulvinatis ; caule brevi, theca tcrminali, pedicello longiori exserta. 

 Hab. same as the former. 

 M. Mitten quotes still 0. elegans, Schwsegr., (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, Bol. 



108. O. rivulare, Turn. 



Hab. roots of elm trees and posts in water, Anderson Valley, etc., quite 

 common, Bol. 



109. O. cylindrocarpum, Lesqx. Pusillum, monoicum subpulviualum. Caulis sim- 



plex vel paree ramosus, obscure viridis, interne 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 perichsetialia vix longiora. Fins 

 masculus in ramo proprio sub pericluetio innovante,-raro axillaris. Capsula 

 in pedicello brevi, exserta, cylindrica, vel cylindrica-ovalis, pallide viridis vel 

 luteola. Peristomii dentes 10 per paria approximati, albidi ciliis S robustis, 

 basi dilatatis aequilongis, duplici serie cellularum formatis, separati. Oper- 

 culum conicum, margine rubellum vaginula ealyptraque anguste conica 

 plicata. valde pilosse.
