Yellow cryptantha (Cryptantha flava, Boraginaceae) can be found in many arid locations in the American west. This perennial inhabits open sandy areas from southern Wyoming down into northern Arizona and New Mexico. It features long, narrow, and densely hairy leaves that are largest near the base and become progressively smaller up the stems. At the end of each shoot is a cluster of tiny, yellow, five-parted flowers that appear from April through August. Although there are over 100 species of Cryptantha in western North America, only two have yellow flowers. The similar basin yellow cryptantha (C. confertiflora) has a more western distribution. Other Cryptantha bear white flowers.
This plant goes by a couple of other common names including yellow miner’s candle and Brenda’s yellow cryptantha. That lead me to wonder “who is Brenda?” Based on this USDA Forest Service information, Brenda is apparently Brenda Casper, a professor of ecology, evolution, and plant biology at the University of Pennsylvania who has performed considerable research on this plant.
