Description
This is a compact subshrub reaching about half a meter-1.5 feet 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.
The inflorescences hold clusters of thick, knobby flower heads. Each head is a capsule of layered greenish glandular phyllaries with an array of many cylindrical, protruding golden yellow disc florets at one end.
