absence of the crown of squamellae, when not a few species of both 
Perityle (in the larger sense) and Laphamia, regularly lack the 
pappus, resulted, of course, in a most arbitrary division of the 
group. 
Certain of the more important species affected by this interpre- 
tation of the generic boundary lines of Perityle and Laphamia are 
the following:

Dr. Gray’s treatment of this plant as a species of Bahia with 
entire leaves seems to me eminently satisfactory. The correct 
binomial, however, is B. integrifolia rather than B. nudicaulis as 
18 shown by the above citations, and the former specific name 18 
available since B. integrifolia DC. Prod. v. 656 (1836) is not a 
Species of Bahia.
