Authentic specimens, under the three names above, prove to be one 

 and the same species. It is doubtful which of the two first specific 

 names is entitled to adoption ; both appear to have been published 

 during the latter part of 1844. This species is dioicous. The true 

 B. radicalis, Beauv., very common in the Southern United States, is 

 monoicous, its staminate and pistillate buds being in close proximity, 

 as in B. pomiformis.
