Perennial herb, woody vine, [shrub], rhizomed, aromatic. Stem: branched, occasionally ± underground. Leaf: simple, basal, cauline, or arising from rhizome, alternate; blade generally cordate, entire. Inflorescence: flower generally 1, axillary or terminal. Flower: bisexual, radial or bilateral; sepals 3, free or fused; petals generally 0; stamens generally 6 or 12, free or fused to style; pistil generally 1, ovary ± or partly inferior, chambers generally 6. Fruit: generally capsule. Seed: many.
5–8 genera, ± 500 species: mainly tropics, warm temperate; some cultivated (Aristolochia, Asarum, Saruma). [Neinhaus et al. 2005 Plant Syst Evol 250:7–26] —Scientific Editors: Douglas H. Goldman, Bruce G. Baldwin.
Key to Aristolochiaceae
Rhizome shallowly horizontal or deeply ± vertical, plants spreading or clumped; roots gingery-aromatic. Leaf: from rhizome, generally evergreen; blade cordate to reniform. Inflorescence: flower terminal, at ground level. Flower: generally dark colored; sepals forming tube, persistent; stamens 12, free from style, tips generally appendaged. Fruit: fleshy capsule. Seed: with fleshy appendage, ant-dispersed.Key to Asarum
90 species: northern temperate. (Greek: derivation unknown) [Kelly 2001 Syst Bot 26:17–53]
Plants generally spreading, forming loose mat; rhizomes near soil surface, horizontal. Leaf: blade all green. Inflorescence: peduncle ± horizontal. Flower: calyx lobes 2–9 cm, spreading in flower, long-tapered, maroon (rarely ± green), tube white inside with 1 median red stripe; stamen tip < pollen sacs, dark.
2n=26. Moist places in forest; < 2200 m. Northwestern California, High Cascade Range, Central Coast, San Francisco Bay Area; to British Columbia, Montana. Plants with short, reflexed, tapered calyx lobes from High Cascade Range (McCloud River) resemble Asarum lemmonii but have horizontal inflorescence and longer calyx lobe taper.
