climbing shrub with greenish flowers. It corresponds with the type 
in all important features but has considerably larger leaves, in some 
instances as much as 8.5 cm. long and 5 em. wide.

The species here discussed have in general involucres somewhat

the scales are regularly imbricated in four or more series, the inner 
tend early to spread so as to give the involucre (at least in the dried
