Flowers: Peduncles slender, 1-5 cm long, few to many flowered, pedicels 5-12 mm long, sparsely puberulent with spreading hairs; calyx lobes ovate, 1-1.5 mm long, puberulent, corollas purplish, 8-10 mm broad, lobes acute to slightly acuminate, sparsely puberulent to subglabrous without, ciliate on margins, glabrous within, corona ring rectanguloid, widest below middle, .5-.8 mm high, free from vesicles. Fruits: Follicles slender 6-9 mm in diameter, attenuate at each end, 7-11 cm long. Ecology: Found along arroyos and in arid valleys below 5,500 ft (1676 m); flowers February-September. Notes: Leaves can be diagnostic for this species, as can its drier habitat. Ethnobotany: Plant was eaten raw, the sap secretions were heated over coals and eaten like gum by the Papago. Etymology: Funastrum is from funis, a rope, cord, or sheet and astrum, incomplete resemblance, while cynanchoides refers to being like the genus Cynanchum.
