On account of its leaves being petiolate, and its connate bracts, 
which do not hide the calyx, this species must be placed next to B. 
rostrata or caudata, if we follow Cogniaux’s monography in DC. 
Mon. 7: 1077. But the leaves of those species are quite different 
and their flowers are long pedunculate. 
On account of the habit, our species is very much like 2. 
grandifiora Hemsley. The leaves are almost identical, but the 
flower is much smaller, the bracts and sepals acuminate and the 
innumerable crystals of oxalate under their upper epiderm. This 
last character may be seen equally well on the leaves of B. frzxervia 
which differs, however, from ours by having the bracts free, and long 
peduncles, measuring 5-6 cm. and exceeding very much the length 
of the petioles.
