This imperfectly known species is very closely related to 

 V. gnaphalifolia A. Rich., chiefl}^ 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. gnaphalifolia. Perhaps differing constantly in 

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

 ated, pappus whiter. »
