Lake dock

Family: Polygonaceae · Type: perennial · Native

Lake dock is a native perennial found in the Great Basin Mountains, particularly in the Mono Pass region, inhabiting beds and shores of slightly salty lakes at elevations of 1,000 to 2,500 meters. Flowering from March to June, this plant produces small flowers in dense, interrupted whorls with branches clustered along the stem. Growing 4 to 7 decimeters tall with decumbent to erect stems that feature axillary shoots, it develops a distinctive vertical or creeping taproot. Its lance-ovate leaves measure 3 to 7 centimeters long, with terrestrial leaves featuring a papillate hairy undersurface and margins that can be flat or slightly wavy. The fruit is small, measuring 1.5 to 2.2 millimeters long and appearing brown or dark red-brown.
