are not conclusive the plant here treated as H. sessilis was presumably 
intended. The Carolina plant, as shown by herbarium material, does 
not have the flower strictly sessile, nor are the leaves as large as in 
Dillenius's plate; but the latter besides being crude was made from a 
cultivated plant. In view of this plant from “Carolina” it would 
be unwise to set up as a distinct species the plant we actually know 
from that region. 
Fra. 8. H. sessilis and seed. 
Some excellent specimens in the herbarium of the Missouri Botanical 
Garden were sent to Bernhardi labeled in Engelmann's hand H. 
erecta & aestivalis; other material originally retained by Engelmann 
(with Lindheimer's field label) is unmarked, but is identical with 
the material sent Bernhardi and the fragmentary plants in the 
Gray Herbarium, originally marked by Dr. Gray as var. aestivalis. 
These specimens are without seeds but they seem identical with the 
material from the southeastern United States that is called HM. 
sessilis.
