_ T. Anderson founded this species, by uniting Barter 845 and 913, and ascribing to 
them the character “ two anticous calyx-segments connate more than half-way up,” which 
is not the case ; in both of them, and in all the material brought here, these segments 
are (as throughout the genus) nearly free. Barter 845, with scabrous leaves, is
