This species shows affinities to W. obcuneata in the general form of the lamina and in 
the tomentum, though in XN. pulvilla all the parts are much smaller and the median 
lobe is characteristically trilobed at the apex (Pl. 28. fig. 4); the calyx and carpels also 
show important specitic differences. The leaves show some resemblance to the young 
leaves of NW. sajamensis, since the lateral lobule of the leaf-lobes grow up to form little 
bunches somewhat as in that species. 
There seems to be a fairly close alliance between this species and NW. obcuneata, 
N. famatinensis, N. transandina, and N. Friesii.
