only by Watson is Ruby \'alley E. Nevada, but what seems to be 

 the same occurs in various places from Colorado Springs, Colo- 

 rado to Oregon.

 Bull. 25 284, A. pabularis A. Nelson. The first is a form with 

 sides of bracts unappendaged and with linear leaves ; the last is a 

 form with margins of bracts greener, more bluntly toothed and 

 with sides occasionally .^oothed. 



A. KuUallii v ar. Utahensis. 



This is a form with linear leaves, and fruit a nearly round and 

 sessile burr with very short and sharp processes all over it. This is 

 No. 1760 Jones from Salt Lake Citv, and is the more common form 

 in Utah. 



Var. falcata. This is like the var. anomala, but with leaves 

 still narrower and longer; flowers densely clustered in the axils, 

 many, the central 1-3 on filiform pedicels 1-4 lines long; fruiting 

 bracts linear lanceolate, falcate, entire, acicular at tip, about 4 lines 

 long, prismatic, about i line wide, mostly without teeth on the 

 face and without green margins, the outer flowers nearly sessile 

 with shorter tips and copiously muricate or toothed on the sides 

 and margins below. This simulates A. phyllostegia in the peculiar 

 development of the flowers. This apparently very distinct species 

 connects with the var. anomala through western Utah forms.

Var. anomala. 



Leaves nearly linear, 4-24 lines long, sessile many ; flowers of 

 both kinds in simple or leafy and panicled spikes ; fruiting bracts 

 sessile, with an ovate base and long-accuminate, about 3 lines long, 

 without teeth, rarely obscurely muricate on the face or with an oc-
