Isocoma arguta is a rare species of flowering plant in the family Asteraceae known by the common name Carquinez goldenbush. It has been found only in Solano and Contra Costa Counties in California , where it grows in the Sacramento-San Joaquin River Delta.[3] It is a resident of Suisun Marsh. It thrives on alkali flats and other mineral-rich soils.
Description
Isocoma arguta is a compact subshrub reaching about half a meter-1.5 feet (20-60 inches) tall and wide with erect, multibranched stems. The hairy stems bear small gray-green, nonfleshy, glandular leaves each less than 2 centimetres (0.79 in) long.[4]
The inflorescences hold clusters of thick, knobby flower heads. Each head is a capsule of layered greenish glandular phyllaries with an array of 10-13 cylindrical, protruding golden yellow disc florets at one end. There are no ray florets.[4]
