This plant, which was sent to the writer by Mr. T. 8. Brandegee, 
proves to be a near relative and evident congener of the problematic 
species originally decribed as Bahia sinuata by Lessing and later rede- 
scribed by Dr. Gray as B. nepetaefolia. Both plants differ from the 
more typical species of Behia in general habit, in the broad leaf-blades, 
which are very shallowly if at all cleft or lobed, in the absence of rays, 
and in the strongly unsymmetrical pappus. ‘T'o judge from Dr. Gray's 
description and notes relating to his B. nepetaefolia, he was much in- 
clined to regard the plant as belonging to a separate genus and only 
referred it to Bahia from a reluctance to increase the number of mono- 
typic genera. The discovery by Mr. Purpus of a second plant main- 
taining perfectly the generic distinctions of the first seems NOW to 
warrant fully the recognition of the two as an independent genus.
