14. BRAOH^ODUS Furnr. 

 (Brachydontium Bruch, Braithw. Br. M. Fl.) 



Plants very small, resembling Seligeria. Calyptra mitri- 

 form, 5-lobed. Capsule erect, oblong, finally striate ; peristome 

 teeth confluent at base, broad, very short and truncate, dotted, 

 thin. 



1. Brachyodus trichodes Furnr. (Gymnostomum trichodes 

 W & M. ; Brachydontium trichodes Fiirnr., Braithw. 

 Br. M. Fl.) (Tab. XIII. K.). 



Plants resembling Seligeria pusilla ; very small, simple, 

 gregarious, green or brownish. Leaves straight, lanceolate- 

 subulate, channelled, entire ; nerve excurrent, forming the whole 

 of the upper part of the subula ; cells hexagonal-rectangular 

 below, irregularly quadrate above. Capsule on a slender seta, 

 oblong, pale, thin-walled, red at mouth, when old more or less 

 pyriform, darker coloured, and finely striate; calyptra conical, 

 j~5 lobed at base ; annulus broad ; lid conical with a straight 

 subulate beak ; peristome teeth irregular, perforated, pale, 

 smooth, very short. Autoicous. 



Hab. Wet sandstone rocks. Not unfrequent in mountainous countries. Fr. 

 early spring. 



Much resembling a Seligeria in habit and leaf structure, this is easily recognised 

 under a good lens by the oblong capsule, on a straight seta, with very fine longitudinal 

 striations ; in leaf it is perhaps nearer S. paucifolia than any other. 



Tribe j. Cynodontiese. 



15. S^LANIA Lindb. 



Plants small ; leaves small, linear or lanceolate, smooth ; 

 glaucous at back with cellular, granulose "bloom." Capsule 

 oblong-cylindric, erect, slightly furrowed when dry ; lid conical ; 

 peristome teeth 16, irregular, cleft to base into two narrow, 

 nodose, papillose divisions, usually much connected above. 



The plant for which Lindberg created this genus has usually 

 been placed under either Ditrichum or Trichostomum, and it 

 certainly holds, as pointed out by Braithwaite, a somewhat
