A fast-growing, mounding perennial up to 90 cm tall covered in finely textured foliage. The leaves are oppositely-arranged, shaped imparipinnate, and evergreen. The sessile leaflets are narrow and long, with a smooth margin. The inflorescence is a corymb, topped with brilliant greenish-yellow daisy-like flowers. After the flowers have bloomed, they produce achenes. This species was described by Townshend Stith Brandegee in 1890.

Uses
Available from nurseries specializing in xerophytic or Baja California plants, this species is an adaptable, durable, and drought-tolerant plant. It grows readily on a number of soils, including sand, clay, and rocky substrates. It grows in dry conditions but is tolerant of extra water, and thrives in both half-shady to full sun locations. It typically blooms in the month of November, providing flowers in a period when typically summer bloomers have gone to seed and winter bloomers have yet to open.
