This imperfectly known species is very closely related to 

 V. gnaphalijolia A. Rich., chiefly differing in its very low sta- 

 ture and reduced inflorescence. In my notes from the Paris' 

 Herbarium I have written as to V. crassinervia: Strongly re- 

 sembling V. gnaphah folia. Perhaps differing constantly in 

 the acute leaves. Veins not prominent beneath. Scales elong- 

 ated, pappus whiter.
