 heads rather small, panicled. discoid, whitish; involucre more or less 

 graduated, the phyllaries mostly linear, strongly few-ribbed, narrowly

 Rydberg 59 and by Wooton and Standley. 60 There is no specimen from Arizona 

 in the United States National Herbarium or in the herbarium of the New York 

 Botanical Garden, and it seems best to omit the species until a definite specimen 

 is forthcoming.
