EOL Text
Erect perennial herb. Leaves lanceolate; margin usually undulate and strongly crisped. Inflorescence usually simple or little branched. Fruit perianth segments ovate-cordate, usually all three with tubercles; margin entire or minutely dentate.
Distribution: Probably indigenous in Europe and SW Asia; evidently rare in Pakistan and India. Introduced and largely naturalized over most parts of the world except the Arctic and the Tropics.

crispus: with a wavy or curled margin
Plants perennial, occasionally bi-ennial, glabrous or very indis-tinctly papillose normally only on veins of leaf blades abaxially, with fusiform, vertical rootstock. Stems erect, branched distal to middle, 40-100(-150) cm. Leaves: ocrea deciduous, rarely partially persistent at maturity; blade lanceolate to narrowly lanceolate or lanceolate-linear, normally 15-30(-35) × 2-6 cm, base cuneate, truncate, or weakly cordate, margins entire to subentire, strongly crisped and undulate, apex acute. Inflorescences terminal, occupying distal 2 of stem, dense or interrupted at base, narrowly to broadly paniculate, branches usually straight or arcuate. Pedicels articulated in proximal 3, filiform, (3-)4-8 mm, articulation distinctly swollen. Flowers 10-25 in whorls; inner tepals orbiculate-ovate or ovate-deltoid, 3.5-6 × 3-5 mm, base truncate or subcordate, margins entire or subentire to very weakly erose, flat, apex obtuse or subacute; tubercles normally 3, rarely 1 or 2, unequal, at least 1 distinctly larger, more than (1-)1.5 mm wide. Achenes usually reddish brown, 2-3 × 1.5-2 mm. 2n = 60.

This adventive perennial plant is 1–3' tall and little branched, except where the flowers occur. Initially, it consists of a rosette of basal leaves about 1' across. A flowering stalk bolts from this rosette during the late spring. This stalk is round in cirumference, hairless, and ribbed. The alternate cauline leaves are up to 6" long and 1" across (excluding their petioles). They are oblong-lanceolate, hairless, and dull green. Their margins are crisped and undulate up and down. Their petioles are up to 2" long, becoming broader at the base. The basal leaves have a similar appearance, except that they are somewhat larger in size, their petioles are longer, and their margins are less crisped or wavy. The inflorescence consists of a panicle of racemes with whorls of flowers; it is about ½–1½' long. Each plant has perfect (bisexual) and pistillate (female) flowers; they are pollinated by the wind. Each yellowish or reddish green flower is about 1/8" long and consists of 3 inner sepals, 3 outer sepals, 3 styles, and an ovary. Perfect flowers also have 6 stamens. There are no petals. Each flower has a drooping pedicel about ¼" in length. The blooming period occurs during the summer and lasts about a month. There is no floral scent. Each flower matures into a dry fruit about 1/6" long that contains a single seed. The inner sepals become larger in size and membranous (at this stage, they are often called 'valves'). Each membranous sepal is cordate-oval in shape and only slightly indented or well-rounded at the base. There is an elongated tubercule that is about 1/3–1/2 the length of the sepal. The margin of each sepal can be smooth or irregularly undulate, but it lacks conspicuous teeth of any kind. The fruit and stems of Curly Dock become dark brown with maturity. The rather large seeds are dark brown and 3-angled, tapering at their tips. They are distributed to some extent by wind or water while adhering to the membranous wings of the fruit. The root system consists of a stout taproot that has a pale yellow interior. This plant spread by reseeding itself. Cultivation

Perennial with tap root. Stem erect, up to 1 m high. Branches erect or erect-patent forming a narrow panicle. Leaves all lanceolate, narrowed at both ends, acute, crispate, up to 30 cm long and up to 6 cm broad, broadest in the middle; petiole shorter than the blade; stem leaves similar, upwards gradually smaller, narrower and with shorter petiole. Flower whorls many-flowered, contiguous, the lowest ones only remote and with a subtending leaf. Pedicels thin, of varyig length, usually about twice as long as the valves. External perianth segments appressed to the valves, nearly as long as half of the breadth of the valves. Valves usually 4-5 mm long and broad, rotundate or subtriangular-cordate, finely articulate, entire or subentire, all or the anterior one grain bearing. Nut c. 3 mm long, brown, broadest below the middle.
