DICRANACE^E.J 146 [Dicranum. 



base elongate-rectangular, hyaline and wide next the nerve, the angular 

 colored narrower and incrassate, the upper small narrowly rectangular. 

 Setae 2 5 in the same perich. rather short, slender pale often convolute, 

 bracts broad short ovate, suddenly aristate, inner oblong convolute, 

 tipped with the excurrent nerve, innermost lingulate obtuse, nerveless ; 

 caps. Isptodermous, exannulate, cernuous and horizontal, oblong, 

 subarcuate, obsoletely striate, olivaceous green, when old black and 

 strongly incurved, lid with a very long subulate oblique straw-coloured 

 beak, falling with the calyptra, teeth ferruginous red, rather short. 



Male infl. gemmiform, nidulant in the cauline tomentum. 

 HAB. Banks and rocks in subalpine woods ; not uncommon. Fr. 7 8. 



Except Dillenius, Smith and Turner, all the older botanists confounded 

 this with D. scoparium, from which it is readily distinguished by the polysetous 

 inflorescence, although occasionally solitary capsules may be met with. 

 Dr. Taylor erroneously regarded it as the true Br. scopavium of Linnaeus.
