Norte Mexico, San Luis Potosi (Virlet d’ Aoust). 
Fournier fully describes the North-Mexican form, which he regards as identical 
with DeCandolle’s original argenteus, and as constituting a species distinct from that 
ordinarily accepted as A. argenteus, and he also points out the distinguishing charac- 
teristics of the forms named argenteus by Kunth, Desveaux, and others. On the other 
hand, Hackel (Mart. Fl. Bras. ii. 3, p. 292) treats the argenteus of all the authors 
named, including Fournier, as one of the numerous varieties of the A. saccharoides, 
Swartz.
