This species is closely allied to B. bicolor 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 ; in dense pulvinate caespitose 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.,

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

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

 B. ery thro carp on, rhomboid-hexagonal, at base rectangular. Caps, on a 

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

 pyriform, regular or slightly arched, blood-red, blackish by age ; lid

 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.
