BASELLACEAE BASELLA FAMILY

Michael A. Vincent

Perennial herb vines, ± fleshy, glabrous. Leaf: simple, alternate, petioled [not], entire [toothed]; stipules 0. Inflorescence: panicle [raceme, spike], axillary or terminal; pedicel subtended by bract. Flower: generally bisexual, radial, immediately subtended on pedicel by [1]2 bractlets; sepals 2; petals [4]5[–13], ± fused basally into shallow cup; nectary a ring; stamens [4]5[–9], from petal cup, basally fused, basally widened; ovary superior, chamber 1, styles [1]3, ± fused basally. Fruit: utricle, indehiscent, fleshy or papery, enclosed in dry perianth. Seed: 1.
4 genera, ± 20 species: tropics, subtropics, mostly America; some cultivated (Anredera, ornamental; Basella, edible leaves; Ullucus, edible tubers). [Bogle 1969 J Arnold Arbor 50:590–598; Nowicke 1996 Syst Bot 21:187–208] Based on anatomy, some authors interpret sepals as bracts, petals as sepals; Basella alba L. cultivated in California. —Scientific Editor: Thomas J. Rosatti.

ANREDERA MADEIRA VINE
Inflorescence: raceme or panicle of spike-like racemes; bractlets fused basally into cup. Flower: calyx, corolla ± spreading to ± reflexed, ± similar; stigmas club- or head-shaped or 2-lobed.
± 14 species: tropics, subtropical America. (Evidently for a person named Anreder) [Van Steenis 1957 Fl Malesiana I 5:302–304]

A. cordifolia (Ten.) Steenis MIGNONETTE VINE
AGRICULTURAL, GARDEN, OR URBAN WEED
Roots tuber-like. Stem: axils with small tubers. Leaf: 2–10 cm; blades ± cordate to ± round. Inflorescence: ± 30 cm; pedicels < 2 mm. Flower: generally functionally staminate; ± 6 mm diam; perianth ± white, fragrant, ± black in fruit; styles 1–1.5 mm, fused in basal 1/2–2/3. Fruit: ± spheric, 0.8–1.1 mm (0 in California). Seed: rarely viable.
2n=24. Uncommon. Disturbed, ± urban areas, abandoned orchards; < 500 m. San Francisco Bay Area, Outer South Coast Ranges, South Coast; native to South America. [Boussingaultia cordifolia Ten.; Boussingaultia gracilis Miers; Boussingaultia gracilis Miers var. pseudobaselloides (Hauman) L.H. Bailey] Spreads rapidly by stem tubers; shown to have anti-inflammatory, anti-ulcer, liver-protective effects in rats. Jul–Nov
