Bryace-e.] 179 [Bryum. 



sharp-pointed purple, shining ; teeth pale ferruginous, endostome pale, 

 with 2 — 3 cilia. Male plant more slender, infl. terminal, thick and 

 gemmiform, internal bracts broadly obovate, cuspidate. 

 Hab. — Gravelly and sandy heaths and on walls. Fr. 6 — 7. 



This species is closely allied to B. Ucolov Dicks., but the fruit is larger 

 and more tapering into the seta, and the leaves more attenuated at points. 

 The seta varies considerably in length, and the capsule in colour from a light 

 rusty brown to the deepest purple red.

Dioicous; densely tufted, leaves shorter lanceolate, with small 

 narrow cells, entire, nerve excurrent in a long point. Caps, pendulous,

Dioicous ; in dense pulvinate csespitose tufts, green above, brownish 

 green when old, interwoven with dense tomentum ; stem short, fastigiate- 

 branched. Leaves erecto-patent, when dry imbricated, rather rigid, 

 the upper crowded into a gemmiform coma, lower comal longish lane, 

 inner from a broad base, lanceolate, lower crowded, shorter, not limbate, 

 a little reflexed at margin, entire at apex, all longly cuspidate with 

 the excurrent rufous nerve ; cells smaller and more linear than in 

 B. erythrocarpon, rhomboid-hexagonal, at base rectangular. Caps, on a 

 dark purple seta arched at top, pendulous, with the neck clavato- 

 pyriform, regular or slightl}' arched, blood-red, blackish by age ; lid 

 large, almost hemispherical, obtuse or with a very small apiculus, 

 purple, shining, annulus broad; teeth large, endostome yellowish,

Intermediate between B. eyythrocavpon and B. Ucolov, resembling the 

 former in the shape of the capsule, and the latter in the leaves, the cells of 

 which are denser than in either, the obtuse lid is also a marked feature.
