B. radicalis is very near the European B. rigida, whose place 

 in this country it seems to supply. The latter species, however, 

 has a less linear leaf, papillose on the lower surface only and 

 refiexed on the margins, a thicker and shorter pedicel, and an 

 oblong-globose capsule with a thicker exterior membrane.
