M. Casimir de Candolle, to whom I sent fragments of Kuntze’s 
cotypes of E. hirsuta for comparison with the Prodromus type of S. 
Dombeyana, states that the latter is distinguished by its more hairy 
achenes with awns nearly as long as the paleae, and by the more long- 
triangular leaves with the long hairs thinner and the short ones nearly 
pulverulent.
