Herbs, perennial, sometimes annual, sparingly glandular puberulent to spreading viscid-villous. Stems often reddish, 0.1-1.5 m. Leaves progressively reduced distally; distal leaves proportionately narrower than proximal; larger leaves: petiole 2-25 mm, equaling or shorter than blade; blade usually flat, sometimes undulate, 20-65 × 10-35 mm, base often oblique, obtuse, or round, margins entire or sinuate, apex acute, sometimes obtuse or round. Inflorescences: peduncle 3-25(-30) mm, involucres ovoid when mature, 4-6.5(-9) mm. Perianth deep pink to magenta, 5-15 mm. Fruits deeply convex, 2.9-4.7 × 1.5-2.8 mm; lateral ribs with 0-4 teeth, teeth usually broadly (rarely narrowly) triangular, never gland tipped, or edge of fruit wings entire or with only irregular undulations and incisions, concave side of fruit with 4-7 glands per row (glands rarely continuous or 2 rows glandless); stalks equaling or shorter than diameter of glandular head. Allionia incarnata was used by indigenous peoples to treat swellings, was added to baths to reduce fever, and also prepared as a decoction to treat diarrhea and kidney ailments (S. Cheatham et al. 1995, vol. 1). Occasionally fruits of A. incarnata are shallowly convex and resemble, in this respect, the fruits of A. choisyi.

Duration: Perennial Nativity: Native Lifeform: Forb/Herb General: Ephemeral annual or short-lived perennial herb with stout taproot, dying back to roots during drought; Glandular hairy and sticky viscid throughout except the flowers, often with sand sticking to herbage. Stems sometimes reach more than 1 m. Leaves: Opposite, petioles 0.2-3.5 cm long, leaves 2-6 cm long, broadly deltoid-orbicular to oval, usually rounded at base, unequal, green above, paler beneath. Flowers: Involucres on slender peduncles 3-5 cm long, lobes free, ovate-orbicular, 5-9 mm long, perianth 6-15 mm long, purplish red, rarely white. Fruits: Anthocarp 3-4.5 mm long, inner side 3-nerved, margins with 3-5 broad teeth or sometimes entire, strongly incurved. Ecology: Found in sandy or rocky soil; 6,000 ft (1829 m); flowers April-October. Distribution: s CA, s NV, s UT, AZ, s CO, NM, s OK, TX; south to s MEX, and in S. Amer. Notes: Prostrate perennials densely hairy; the showy, pink -flowers- are actually three separate flowers snugged together arising from fused bracts (involucre); the fruits are hard and have claws or teeth that bend over a cavity. Ethnobotany: Unknown Etymology: Allonia is from Greek allos, meaning different or other and incarnata means flesh-colored. Synonyms: None Editor: SBuckley 2010, FSCoburn 2015
