Nearly related to V. gigantea, Jacq., but with internodes winged 
throughout, leaf-divisions more numerous, heads more slender-pedi- 
celled, ete. An examination of the type material of V. pinnata, 
Clark, preserved in the De Candollean herbarium, at Geneva, shows 
it to be a plant quite distinct from this with leaves scabrous above 
and merely auriculate not decurrent at the base. ;
