Diplacus grandiflorus, the large-flowered bush-monkeyflower, is a species of flowering plant. It is a subshrub or shrub endemic to the northern Sierra Nevada of California. It grows on steep canyon banks and rocky hillsides from 90 to 1530 (1830) meters elevation.
The taxon was first described as Diplacus glutinosus var. grandiflorus by John Lindley and Joseph Paxton in 1852. In 1854 François Hérincq elevated it to a full species as D. grandiflorus. D. grandiflorus is a later homonym which is now considered a synonym of D. aurantiacus. References
