Resembles JV. mida and W. divaricata in the absence of bractlets, 

 but has a longer style and the fruit is more acute at the upper end. 

 It differs from the former in the shape of the leaf-segments, which in 

 W. nuda are more rounded and with rounder teeth. The form of 

 the leaf is most like that of W. longistxlis and of the fruit most like 

 that of W. Claytoni. In W. divaricata, which is really its nearest 

 ally, the pedicels are divergent in fruit at nearly right angles, the 

 fruit generally decidedly curv^ed and thickest near the apex and the 

 stylopodium more depressed.
