Leaves: Leaves thick, pubescent and soft, ovate to lanceolate, 4-10 cm long. Flowers: Solitary in the leaf axils or on axillary racemes, small, calyx 5-6 mm long, petals 6-9 mm long, bright orange, to yellow. Fruits: Schizocarp sparsely puberulent 7-8 mm with winged mericarps or capsules, lower mericarp chamber 1 seeded, upper chamber 1-2 seeded. Ecology: Found on dry sites often on volcanic or granitic substrates on rocky or gravelly slopes, canyons, and arroyos from 1,000-3,500 ft (305-1067 m), flowers throughout the year. Distribution: Ranges across southern Arizona, south to Baja California and Sonora and west to California. Notes: Distinguished in the genus by the yellow flowers and within the family by the calyx not being inflated and having fewer mericarps than Abutilon and having a prominent wing at the apex of the mericarp.
