212. Ulota Uiitchinsiae rufescens Britt. — Plants more slender than the 

 species, green or brown, not black: stems rufous tomentose: leaves less 

 crowded, longer, acuminate; cells more dense and obscure, lower golden 

 brown, rectangular, not linear or sinuous, marginal "shorter, not hyaline: 

 capsule pyriform, inflated, narrower at mouth; peristome double, teeth 

 reflexed when dry, white, granulose, not trabeculate at apex; cilia 8, of 

 two rows of cells, fugacious. Bull. Torr. Bot. Club 12: 69. 1894.— On 

 trees in dense woods. 



213. Orthotrichum Shawii Wils. — Monoicous: tufts lax, 1-2 cm. high, 

 brownish radiculose at the base, green, olive-green or brownish above:, 

 leaves loosely imbricate when dry, when moist reflexed and spreading from 

 an erect base, lanceolate from an ovate base, long and narrowly pointed, 

 margins more or less revolute; costa vanishing below apex, lamina uni- 

 stratose; cells papillose, thick walled, round-hexagonal, above larger and 

 oval, near base elongated rectangular, at angles shorter and broader: 

 perichsetial leaves erect, less keeled, inner often smaller: capsule ovate, 

 immersed, neck half length of capsule, gradually narrowed into seta, when 

 dry and empty almost urnshaped, light weak folds above; lid short, bor- 

 dered with orange colored cells; annulus persistent, 2-3 rows of cells; per- 

 istome simple, teeth 16, when dry reflexed, linear lanceolate, pale, split in 

 middle here and there along middle line, thickly papillose. Limpr. Laubm. 

 1: 90. Bry. Eu. Suppl. Orthotrichum, pL 1. — California. 



214. Ortliotrichum fasti^latuiu Bruch. — Closely allied to O. affine, 

 but generally smaller, tufts only 1 cm. high: stem reddish radiculose, 

 fasciculately branched: leaves more rigid, when dry appressed, when moist 

 reflexed and erect spreading, shorter and broader, long lanceolate, mostly 

 short pointed, keeled, plicate at base, margin revolute; costa percurrent; 

 cells on both sides with simple or furcate papilla, the upper thick-walled, 

 roundish, in point larger, oval or oblong, at base linear (1:6), more trans- 

 parent, at angles much shorter: perichsetial leaves larger and broader, the 

 inner with plane margins: capsule immersed, somewhat thicker, long 

 pyriform, 8 costate; neck furrowed and gradually narrowed to seta; annulus 

 of one or two rows of cells: peristome double, light yellow, teeth eight, 

 when dry reflexed, trabeculate at apex, vermicular striate; cilia 8, robust, 

 shorter than teeth. Limpr. Laubm. 1: 82. — Lake Superior. 



215. Orthotrichum Sprucei Mont. — Autoicous: in dark green, spar- 

 ingly branched tufts: leaves erect, loosely imbricate when dry, erect 

 spreading when moist, ovate-spatulate, rounded at point and muticous or 

 with a small apiculus; margin revolute at base, then recurved to some dis- 

 tance below summit; cells at base quadrangular, elongated near nerve, pass- 

 ing gradually into large, rounded or angular, smooth or faintly papillose
