Drawn last summer in the hothouse of the Botanic 
Garden of Comtesse des Vandes at Bayswater; where the 
plant has been now first introduced from tbe Brazils. 
We have referred it to Ruexza, though persuaded that, 
upon a due revision of the order, this genus will be re- 
stricted to the berbaceous portion of the group from North 
America.
