1. Helenium montanum Nutt. Trans. Amer. Phil. Soc. n. ser. 7: 384, 1841. 
Helenium autumnale pubescens Britton, Mem. Torrey Club 5: 339. 1894. 
Type Locaity: ‘In the Rocky Mountain range, on the borders of Lewis’ River, 
etc.”’ 
RanGeE: Washington and Saskatchewan to New Mexico and Mississippi. 
New Mexico: Taos; Rociada; Pecos; Tularosa Creek; Roswell. Wet meadows, in 
the Upper Sonoran Zone. 
This species is very near Helenitwm autumnale, and perhaps hardly separable from it.

Tall stout perennial herb, with mostly basal, oblanceolate, impressed-punctate 
leaves and several large long-pedunculate heads of bright yellow flowers; involucral

1. Dugaldea hoopesii (A. Gray) Rydb. Mem. N. Y. Bot. Gard. 1: 425. 1900. 
Helenium hoopesti A. Gray, Proc. Acad, Phila, 1863: 65. 1864. 
Type Locauity: ‘South Park and west of Pike’s Peak,’’ Colorado. 
RanGe: Montana and California to New Mexico and Arizona. 
New Mexico: Tunitcha Mountains; Chama; Santa Fe and Las Vegas mountains; 
Baldy; Mogollon Mountains; Iron Creek; White and Sacramento mountains. Mead- 
ows in the mountains, in the Transition and Canadian zones. 
The common name which we have applied to this very abundant and showy Rocky 
Mountain plant is a translation of the one used by the Navahos. It refers to the 
appearance of the involucral bracts, especially in age.
