Description
Eriogonum angulosum is an annual herb producing a spreading to erect stem up to 90 centimetres (35 in) tall. The leaves are located about the base of the plant and on the lower stem. They are lance-shaped and usually quite woolly in texture.
Most of the stem is made up of the inflorescence, an angled, grooved cyme with bell-shaped clusters of flowers at the tips of the branches. The individual flowers are only about a millimeter long and are white to pink-tinged in color with protruding stamens.
Taxonomy
In 1836 botanist George Bentham scientifically described a new species in the Eriogonum genus, which he named Eriogonum angulosum. Along with the rest of the genus it is classified in the Polygonaceae family. Although the species has no accepted varieties, it has three that are botanical synonyms.[2]
