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).
Fruit: body 5–10 cm, fusiform, smooth, rough, or spiny, crested with branched projections generally only along upper suture; claws 1.5–3 × body.
Seed: 8–13 mm, angled, generally black, corky.
8 species: Am. (Greek: elephant's trunk) [Bretting 1982 Amer J Bot 69:1531–1537] Fr dispersed by attachment of claw to animals. Proboscidea parviflora subsp. parviflora not in CA according to some reports, naturalized in CA according to others.
Unabridged note: All CA material previously identified as Proboscidea parviflora subsp. parviflora belongs instead to Proboscidea parviflora var. hohokamiana Bretting, according to some but not all reports; in CA only in cultivation according to some reports, naturalized in CA according to others; in AZ cultivated by Native Americans for fibers from fruit.
