 Known only from northern Arizona. 



Cockerell's record 3 of Hymenoxys lemmoni subsp. greenei Cockerell 

 from Arizona, based on Airs. Thompson's collection [no. 382] from 

 "northern Arizona," rests on a specimen of this species. 



2 The following information regarding; the type locality of this species, derived from the late M. E. Jones, 

 deserves to be placed on record. Nagle's ranch was about 60 miles south of Kanab, Utah, on the west slope of 

 the Buckskin Mountains (i. e. the Kaibab Plateau), and was the first watering place on the old wagon road 

 to the Grand Canyon from Kanab. The old Valley Tan ranch was about 15 miles farther up on the plateau 

 and was the first ranch reached on the way to the Canyon after ascending the plateau. The present wagon 

 road now ascends the plateau many miles farther north. The name Buckskin Mountains, as applied to the 

 Kaibab Plateau, is now obsolete. Recent maps of the State show another ran?e of the same name iust south 

 of Williams River (Bill Williams Fork).
