FI oral bracts 8, 5mta. high, not carinate, linear, abruptly acute,

The above description is based on plants collected in a brushy meadow, 
in the Yellow pine helt, at an elevation of 2550 motors in Lee Canon 
Charleston Jits., Clark Co., Nevada, where it is locally abundant. 
My Number 5638, deposited An my herbarium is designated as the type. 
Material of the type collection and number is being distributed in 
the I£ks1c catae Grayanae. 
This species belongs to the Suffruticosi Groenman ( Greenman Monograph 
- der Gattung Senecio, Leipzig, 1901) or-4 and to Longilobi ( 
Rydberg,(Rocky Mountain Flora) Owing to the narrowly linear entire 
leaves it could be confused only with denecio spartioidos T. & G. 
From this species it can he separated by the following key* 
Bracts 8, not carinate, 5 raa. long, achene3 glabrous 
Seheolo sn. nov . 
fracts about 12, carinate, long, aohenes silky 
canescent. Henecio s partioides T. & G. 
I have not stated the length of the bracts for S. spartioldes in the 
above key. They are manifestedly considerably longer than this 
specimen but I had available only a few specimens of S, spartioides 
mostly my own collections from Colorado, so I hesitated to fix these 
measurements. In Comparing this material will you kindly note the 
length of floral bracts for a few specimens of S, spartioides.
