PLANT: In AZ a vine 0.5-3 m long, densely pilose throughout.

LEAVES: palmately 3(-5) lobed, the margins usually erose serrate or incised serrate, ciliate with gland tipped cilia; petiole with gland tipped cilia; stipules cleft to near base into numerous conspicuous gland tipped cilia or segments.

BRACTS: 18-27 mm long, 7-15 mm wide (to 45 mm long, 27 mm wide in fruit), lightly pilose, deeply bipinnatifid, the segments, cilia, or teeth glandular tipped.

FLOWERS: ca 4-5.5 cm in diameter, whitish, the corona white or purplish; sepals subequal to or slightly shorter than petals; coronal filaments in ca. 6 series, the outermost 10-17 mm long, the inner ca. 4 series 2 mm or less long; ovary long pilose.

FRUITS: ca. 2.5-3 cm in diameter, globose or widely ellipsoid, greenish or yellowish.

SEEDS: ca. 5.6-6.3 mm long, 3.3-3.9 mm wide, pitted, apically tridentate.

NOTES: Outcrops in desert grasslands: Pima, Santa Cruz cos.; 1150-1700 m (3700-5600 ft); Jun-Oct (fr. Aug-Oct); Son., Mex., and widespread throughout tropical America, introduced in warm regions worldwide. This species has 38 varieties according to the last monographer, Killip. The one variety (var. arizonica Killip) that he recognizes as occurring in Arizona might deserve recognition at the species level. It differs from other vars. in having leaves that are deeply lobed, with the central lobe often narrowed near its base, the lateral lobes themselves lobed, and the margins erose serrate.
