FLOWERING PLANTS AND FERNS OF ARIZONA 193 



Key to the species 



1. Inflorescence subcapitate or, if more open, then the rays very unequal; bracts 

 large, ovate or ovate-lanceolate, white or tinged with blue; perianth blue 

 violet, the lobes ovate, obtuse, less than twice as long as (often little longer 

 than) the broadly campanulate tube 1. B. c a pit at a. 



1. Inflorescence umbellate, the rays all elongate and nearly equal; bracts small, 

 lanceolate or oblong, purplish; perianth bright yellow, turning purplish, 

 the lobes lanceolate, acutish, much more than twice as long as the turbinate

1. Brodiaea capitata Benth., PL Hartw. 339. 1857. 



Coconino, Mohave, Gila, Maricopa, Pinal, Cochise, Santa Cruz, and 

 Pima (doubtless also Yuma) Counties, 5,000 feet or (usually) lower, 

 very common and abundant, February to May (rarely in late 

 summer). Southwestern New Mexico to Oregon and California. 



Bluedicks, covena, grassnuts. The violet-colored flowers of this 

 species are conspicuous on the mesas and open slopes in early spring. 

 The bulbs were eaten by the Pima and Pap ago Indians. The form 

 occurring in Arizona is var. pauciflora Torrey (Dipterostemon pauci- 

 florus Rydb.) with a looser inflorescence and paler colored bracts than 

 in the common California form of B. capitata.
