A species, which while only known to us through the 
specimen in the Banksian Herbarium, we had set down in a 
review of this genus, in the Journal of Science and the Arts, 
for the same as the uwndulatum of Messrs. Humboldt and 
Bonpland, a species known to us solely by description from 
the dried subject. But the comparison of our plant in a 
fresh state with this description, has induced us to separate 
the two, though manifestly very near akin. The crown in 
undulatum is described with a pou in each interstamineous
