 obtusely acute, revolute in the middle, carinate, the costa ceasing below the apex, 

 gianulose-pa|)illose above : mona-cious, the male buds axillary, slender : calyptra

14. O. pulchellum, Smith. Stems loosely cespitose, about 3 lines high, very 

 slender : leaves jtale green, soft, spreading, lax and slightly crisped when dry, linear- 

 lancedlate, acuminate, margins revolute below, very minutely punctate and revolute 

 toward the apex : male ilowers terminal : caly])tra campanulate, naked, pale yellow

Clear Lake and Eureka (Bolandcr) ; Vancouver Island ; Northern Europe. Peristome some- 

 what ])nler and pedicel longer than in the Euroi)ean type. 0. Columbicum, from Vancouver 

 Island, is described as having but 8 cilia and the calyptra rugose at the apex. 



0. coNSiMiLF,, Mitt. 1. c. (Sulliv. Icon. Muse. Suppl. 59, t. 43), also from Vancouver Island, is 

 very similar but with shorter capsule, the calyptra somewhat hairy, and the cilia only 8. 



15. O. Lyellii, Hook, t^ Tayl. Stems loosely tufted, 2 to 4 inches long, much 

 branched : leaves crowded, flexuose-.squarrose, when dry nearly erect and somewhat 

 twisted, linear-lanceolate, acute, margins Hat, beset with red clavate hairs or papillae: 

 di(uciou3 : calyptra large, moderately hairy, conic-campanulate : capsule emergent, 

 ovate upon a loiig collum, faintly 8-striate, elongated and deeply striate when dry, 

 yellowish brown : teeth whitish, reflexed when dry; cilia 10, red, slightly erose on 

 the hyaline margin. — Muse. I'.rit. t. 22; Jhuch & Schimp. I.e., t. 221 ; Wilson,

26. ENCALYPTA, Schreb. 

 Somewhat cespitose branching perennials, on the ground or rocks, the stem 

 rhizoid-bearing the whole length. Leaves 5-ranked, dull green, linear to spatulate, 

 densely covered above with cleft papillce ; areolation close hexagonal toAvard the 

 apex, long-rectangular and hyaline at base. Inflorescence monoecious (rarely dioe- 

 cious), bud-like. Calyptra very large, longer than the capsule, cylindric-campanulate, 

 very smooth, Avith long slender beak. Capsule erect upon a long pedicel, oblong or 

 cylindric, Avith a short collum ; operculum beaked like the calvjitra. Peristome 

 very variable, single, of IG teeth (in our species), or double, much as in Orthotrichum, 

 sometimes Avanting. 



A genus of about 20 species, largely European. I'eseuibling in linbit the larger species of 

 Uarbiild, but readily distinguished by the calyptra. 



« Ferlstoniti very fiKjacious and fratjUe, or often wanting.
