Abstract
Cymopterus constancei is described as new from mostly western portions of W yoming, Colorado, and New Mexico and from eastern Utah and Arizona. It has been confused with C. bulbosus A. Nelson but differs in several features of its bractlets, phenology, and habitat. The novelty is among the earliest o f the native flora to bloom and is quite uniform morphologically. The numbe r of collections encountered exceeds 200, a fourfold increase in the past 2 2 years.
