Dimeresia is a monotypic genus in the sunflower family containing the single species Dimeresia howellii, known by the common name doublet. [2] [3] [4]
This uncommon plant is endemic to an area of the Great Basin region in the western United States, in northeastern California, southeastern Oregon, southwestern Idaho, and northwestern Nevada. [2] [5] [6] [7]
It grows in dry volcanic soils, primarily on the Modoc Plateau volcanic plain, at elevations of 1,500–2,400 metres (4,900–7,900 ft). [5]
Dimeresia howellii is a very tiny annual flowering plant rarely exceeding 4 centimeters in height or width. It forms a small tuft on the ground with several oval-shaped leaves, and is cobwebby at base and glandular above. [5]
The inflorescence has tiny white to purple bell-shaped flowers each a few millimeters long. [5] The flowering period is May to August. [2]
