A remarkable species, resembling B. albicans (L.) in habit, but with 
smaller, scarcely plicate leaves, having a very striking basal areolation. The 
lax, pellucid, subquadrate alar cells are abruptly differentiated from the 
upper areolation, reach rather high in the leaf, and not only extend to 
the nerve but cover its ventral surface for some little distance above the 
insertion. 
The flowers are very unusual, if not abnormal. I have dissected out 
several and find them all uniform ; they are very minute in size, position and 
appearance, precisely as one would expect to find the male flowers, and with 
the bracts corresponding to the usual structure in these ; but they all contain 
archegonia, small, but fully developed, deep red, and with every appearance 
of being normal. It would be very desirable to collect fruiting plants of 
this species.
