Wells, etc., Bigelow. This species includes De Candolle's II. elegans and Lis IT. hetcropliylluni, 

 at least in part, viz: No. 2113 of Berlandier's collection, which is from Ileynosa. Do Candolle 

 also cites Berlandier's No. 107 and No. 190, and the habitat Tampico. I have no specimens 

 from that station. From these the character^ ^^ pappi paleis breviter aristatis/' may have been 

 drawn. But in those from Reynosa the palecB are very obtuse and pointless, just as in 

 crocephalum.
