Dryas drummondii

Dryas drummondii Richardson ex Hook.

Drummond's Mountain-avens, Yellow Mountain-avens, Yellow Dryas

Rosaceae (Rose Family)



USDA Native Status: L48 (N), AK (N), CAN (N)

This slow-growing perennial forms mats up to 3 ft. wide and 8 in. tall. The mats appear to be a mass of oval, leathery leaves with rounded teeth. The leaves remain dark green during winter but deteriorate rapidly as new leaves are produced in spring. Single, yellow flowers are borne atop 2-8 in. stems. The petal ascend, rather than spread, in flower; the result is that the flowers never seem to fully open. Summer fruits are fluffy and feathery.

The species name of this plant is named for Thomas Drummond, (ca. 1790-1835), naturalist, born in Scotland, around 1790. In 1830 he made a trip to America to collect specimens from the western and southern United States. In March, 1833, he arrived at Velasco, Texas to begin his collecting work in that area. He spent twenty-one months working the area between Galveston Island and the Edwards Plateau, especially along the Brazos, Colorado, and Guadalupe rivers. His collections were the first made in Texas that were extensively distributed among the museums and scientific institutions of the world. He collected 750 species of plants and 150 specimens of birds. Drummond had hoped to make a complete botanical survey of Texas, but he died in Havana, Cuba, in 1835, while making a collecting tour of that island.
