Taproot branched or tuberous. Stem: prostrate to spreading, generally < 1 m. Leaf: blade broadly ovate to round or triangular, palmately veined (generally palmately lobed), base cordate. Inflorescence: bractlets < calyx. Flower: calyx 1–2 cm, generally 5-lobed, split to base on lower side, or sepals free; corolla 2–5 cm, bell- to funnel-shaped, showy, tube cylindric, generally < 1 cm, bent downward, throat 10–30 mm, limb with 5 flared lobes, throat and lower limb with colored lines (nectar guides).

Seed: 8–13 mm, angled, generally black, corky.Key to Proboscidea
8 species: America. (Greek: elephant's trunk) [Bretting 1982 Amer J Bot 69:1531–1537] Fruit dispersed by attachment of claw to animals. Proboscidea parviflora subsp. parviflora not in California according to some reports, naturalized in California according to others.
Unabridged note: All California material previously identified as Proboscidea parviflora subsp. parviflora belongs instead to Proboscidea parviflora var. hohokamiana Bretting, according to some but not all reports; in California only in cultivation according to some reports, naturalized in California according to others; in Arizona cultivated by Native Americans for fibers from fruit.
