Differs from B. velutinum and B. intricatum: Leaves falcate 

 also when moist, with more or less recurved borders; those of 

 stem more distinctly denticulate, those of branches with long 

 filiform point. Differs also from B. intricatum in decurrent 

 leaves; from B. velutinum in less distant leaves falcate also when 

 dry, those of branches not much narrower, alar cells numerous. 

 Agrees with B. velutinum: Leaves decurrent; pedicel of capsule 

 rough in its whole length etc. — Higher alp. region r. Amer.
