Herbs, perennial, not rhizomatous, 1–5 m. Stems usually scandent or sprawling, rarely erect, freely branched, herbaceous, pilose-hispid or, rarely, subglabrous, not glaucous. Leaves: ocrea usually deciduous, light-brown, cylindric, 3–4 mm, margins oblique, base fringed with reflexed hairs and slender bristles, face glabrous or puberulent; petiole 1–6 cm, retrorsely pubescent; blade cordate-ovate, cordate-hastate, or cordate-sagittate, 2–6 (–12) × 2–5 (–10) cm, base cordate, margins wavy, often reddish-ciliate, apex acute to acuminate, abaxial face pilose-hispid, not minutely dotted, not glaucous, adaxial face glabrous. Inflorescences terminal and axillary, erect or spreading, paniclelike, 4–10 (–15) cm, axes reddish-pilose; peduncle 1–12 cm, retrorsely pubescent. Pedicels ascending or spreading, articulated near middle or distally, 3–4 mm, glabrous or puberulent. Flowers bisexual, 4–7 per ocreate fascicle; perianth nonaccrescent, greenish white to white, 1.5–2 mm including stipelike base, glabrous; tepals elliptic, apex obtuse to acute, outer 3 obscurely keeled; stamens 6–8; filaments flattened proximally, pubescent proximally; styles connate basally; stigmas capitate. Achenes included or exserted, brownish black to black, 3–4 × 1.8–2.4 mm, shiny, smooth; fruiting perianth glabrous, wings absent. 2n = 22.

Discussion

Á. Löve and D. Löve (1982) reported a chromosome count of 2n = 20 for Fallopia cilinodis. All other counts summarized by J. P. Bailey and C. A. Stace (1992) and counts by M. H. Kim et al. (2000) are 2n = 22. It is not known if the 2n = 20 count is an error.
