BOTANY. 99 
Wells, ete., Bigelow. This species includes De Candolle’s Н. elegans and his H. heterophyllum, 
at least in part, viz: No. 2113 of Berlandier’s collection, which is from Reynosa. De 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 paleæ are very obtuse and pointless, just as in H. mi- 
crocephalum.
