An almost BL species in the Temperate Zones, ne some of the 
alpine regions of the warmer regions of the world. It is t difficult to 
recognize, from the synoicous inflorescence, seianaity tall re lax habit, 
and the leaves more or less flexuous when dry, only shortly acuminate, 
margin, ‘at least in the lower we strongly recurved. 
It is probably common, growing in wet places.

‘ rete carefully examined the specimens of B. ereberrimum in the 
herbaria of Packet ‘and Wilson. Hooker’s specimens contain an paenenees 
mixture, some being the true B. creberrimum of Taylor—i.e., B. 4 
but others as certainly B. obconicum. It is, principally at least, on hess 
latter that the description in the Handbook is drawn up, thus accounting 
for the species being there described as dioicous. Wilson in his poe on 
B. ereberrimum appears to have fallen into the same error; he refers to it 
B. australe Hampe, but, I think, incorrectly. He states that he ‘lee not 
found the Swan River plant (2. e., the original of B. creberrimum Tayl.) 
constantly synoicous, writing © “Tn some cases assuredly monoicous; in 
others I see flowers hermaphrodite.’’ This may probably be due to a mixture 
undetected by Wilson, but i is more likely to indicate a heteroicous condition, 
such as occasionally occurs in allied species—e.g., 1 On the 
other hand, I have no hesitation in referri nicum Hampe here.
