Discussion

Variety caelestinum is a high-elevation expression most closely related to var. ovalifolium. In both the Toiyabe and Toquima mountains of Lander and Nye counties, Nevada, and at Tioga Crest in Mono County, California, there is a pronounced elevational difference between the two, with var. caelestinum several thousand feet higher than var. ovalifolium. Heavenly wild buckwheat is occasionally seen in cultivation.
