486. Brachythecium rutabuliforine Kindb. — Agrees with. B. rutabu- 

 lum in very rough pedicel, monoicous inflorescence and form of leaves: dif- 

 ers principally in rigid stem,distinctly appendiculate cilia of peristome, and 

 short pedicel: leaves sub-ovate, short-acuminate, nearly estriate, faintly den- 

 ticulate. Mac. Cat. 198.— On stones in brook: British Columbia. 



487. Brachythecium Colurabico-nitabnlum Kindb.— Tufts dense, faint- 

 ly shining, finally brownish-green: stems elongate, pinnate creeping: stem 

 leaves patent, from broadly ovate base long cuspidate, with filiform gener- 

 ally prolonged point, decurrent, very plicate, nearly entire, borders shortly 

 reflexed below; cells not chlorophyllose, alar larger and well distinct; 

 perichaBtial leaves sub-erect-patent with a long filiform arcuate point, faint- 

 ly and distinctly denticulate: capsule oblong-cylindric, curved; peristome 

 teeth not serrulate, segments very open in middle, cilia faintly nodulose, 

 not appendiculate; pedicel very rough; monoicous. Mac. Cat. 198. — On 

 wet and rotten logs in woods: Columbia River, B. O. 



488. Braehythecium lamprochryseiim C, M. & Kindb.— Tufts large, 

 laxly cohering to substratum, with few rhizoids: golden yellow, shining or 

 finally decolorate: stem elongate, often pinnate; branches generally short 

 or sometimes more elongate and faintly curved above, sub-acute: leaves 

 open, more or less loosely disposed, long decurrent, distinctly auriculate, 

 very plicate, from triangular ovate base short acuminate, filiform or sub- 

 ulate cuspidate, often curved at apex, nearly flat, only auricles faintly rev - 

 olute; borders faintly denticulate all around; most cells very long and 

 narrow, lowest basal ones dilated and short, also the alar, all very spar- 

 ingly chlorophyllose; costa broader at base, faint, reaching to middle, but 

 in the smaller narrower and more loosely disposed leaves of some branch- 

 lets longer, reaching to acumen: perichaatial leaves ecostate, when dry 

 squarrose, inner sheathing with a short subulate acumen and a long fili- 

 form point: capsule short, sub-ovoid, thicker near base, slightly contracted 

 below mouth, arcuate; lid unknown; teeth finally brown at least at base; 

 •cilia not appendiculate; pedicel very rough: monoicous. Mac. Cat. 199. — ■ 

 On stones: Vancouver Island. 



489. Brachythecium mirabniidum O. M. & Kindb.— Tufts large, very 

 laxly cohering, nearly without rhizoids, silky or yellowish green, faintly 

 shining: stem elongate, irregularly divided or prolonged into sciuroid- 

 curved obtuse branches: leaves loosely imbricate, crowded, when dry sub- 

 rugose, when moist patent, short decurrent, indistinctly auriculate, faintly 

 plicate, from concave ovate and gradually acuminate base long cuspidate; 

 borders broadly recurved at least at one side of nearly entire base to invo- 

 lute and distinctly denticulate acumen; cells pale, elongate, narrow, alar 

 sub-quadrate and not much wider than other basal ones, all sparingly 

 chlorophyllose; costa vanishing in acumen: peiichsetial leaves ecostate,
