Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Herbaceous perennial from fusiform tuberous rootstock, stems 1 to several, erect 25-35 cm tall, stipules linear-subulate, 4-7 mm long. Leaves: Alternate, narrow to broadly cuneate, 7-9 lobed, lobes to 2 cm wide, coarsely serrate, rounded or obtuse at apex. Flowers: Sepals narrowly lanceolate, acute or somewhat attenuate, 15-20 mm long; petals orange-yellow with 1-2 maroon spots at base of each, 2.5-3 long; anthers all dark maroon or only lower set dark maroon, ovary densely puberulent papillose. Fruits: Ovoid capsule, 3-4 cm long, pendant, weakly striate longitudinally, 2-2.5 cm wide, finely and sparsely puberulent and with scattered, sessile, reddish glands intermingled with fine crisped hairs. Ecology: Found on dry rocky slopes and mesas from 2,500-5,000 ft (762-1676 m); flowers July-September. Distribution: s AZ; south to c S. Amer. Notes: A showy, charismatic and distinct species with palmate leaves with wavy to deeply-lobed margined leaflets; the flowers and fruits also don-t resemble other species in the area. Alternate species A. gonzalezii is separated from A. palmatifida by its ellipsoid capsule, silky ovary, and lower set of cream-colored anthers as opposed to dark maroon. Howard Gentry reported that this plant yields lots of seed, but it is difficult to grow. Ethnobotany: All parts of the plants were used as food, including roots, young leaves, flowers, fruits and seeds. Etymology: Amoreuxia is named for P.J. Amoreux (1740-1824) a French naturalist, while palmatifida means palmately divided. Synonyms: None Editor: SBuckley 2010, FSCoburn 2015
