70 BKYACE^. [Dicranum. 



8. D. flagellare, Hedw. Tufts compact, bright green; 

 stems short, producing from the axils of the upper leaves small 

 slender fugacious branchlets {flagellce) with very small ap- 

 pressed bracteal leaves: stem-leaves lanceolate-subulate, con- 

 cave, denticulate at the apex, subsecund, the upper twisted when 

 dry ; costa broad, comi^ressed : capsule long-cylindrical, striate, 

 somewhat plicate when dry. — Muse. Frond, iii. 1, t. 1 ; Bryol. 

 Eur. t. 68 ; Braithw. 1. c. 155, t. 23, C. 



Var. subfluitans, Aust. Stems immersed, longer, slender ; 

 leaves more distant. — Bull, Torr. Club, vi. 344. 



Hab. Decayed trunks in deep woods, very common. The variety in 

 depressions of flat roclis; New Yorli, sterile {Austin). 



9. D. fulvum. Hooker. Plants dusky yellow or brownish 

 green, loosely cespitose ; stems solid, curved down at base : 

 leaves spreading, flexuous or falcate-secund, tufted at the apex, 

 crispate when dry, narrowly ovate at base, gradually long-seta- 

 ceous-subulate, canaliculate to the denticulate apex : capsule 

 short-pedicellate, cylindrical-oblong, brown or black, plicate 

 when old; annulus double, narrow. — Muse. Exot. t. 149. D. 

 interrtqytum, Brid. ; Bryol. Eur. t. 69 ; Sulliv. Mosses of U. States, 

 22. Syrrhopodon (?) Eauei, Aust. Bull. Torr. Club, vi. 74. 



Hab. Shaded sandstone rocks in hilly regions ; not rare. 



Judging fi'om tlie description of the author, Syrrhopodon Rauei 

 differs from this species in being less robust, the leaves shorter and less 

 crowded, the areolation less enlarged, the costa not as strong, the male 

 flowers terminal. These are the characters of the young plants of D. ful- 

 vum, the leaves being shorter, less crowded, and of a more delicate texture. 

 The male flowers are always terminal, only imshed aside each succeeding 

 year by the new innovations, the tufted leaves at the tops of the innova- 

 tions giving the stems an interrupted appearance. 



10. D. longifolium, Hedw. Tufts soft, pale or whitish 

 green, glossy; stems arched and geniculate, slender, slightly 

 radiculose : leaves long, falcate-secund, rarely spreading, open 

 at the short lanceolate base, constricted into a very long sub- 

 tiibulose-subulate point, serrate above on the borders and the 

 back ; inner perichsetial leaves convolute and sheathing to near 

 the apex : capsule cylindrical, erect or slightly curved, not stri- 

 ate, yellowish brown ; pedicel reddish in the lower part. — 

 Muse. Frond, iii. 24, t. 9 ; Bryol. Eur. t. 72; Braitlnv. 1. c. 158, 

 t. 24, B. 



Var. strictius, Aust. Stems longer, more rigid, immersed ; 

 leaves shorter, erect. — Bull. Torr. Club, vi. 344.
