About plant names...

These widespread North American native plants have all kinds of colorful common names that relate to the small fork-shaped seeds, which readily hitch rides on passers-by.

Plants: 12-36" (30-91 cm) high, rarely up to 6' (1.8 m). Stems are square in cross-section, nearly hairless, and light green, reddish green, or purple.

Leaves: Lower leaves are odd pinnate clusters on long petioles, in opposite pairs; upper leaves may be alternate. Leaves are up to 3" (7.6 cm) × 1" (2.5 cm), coarsely toothed, deltate or lanceolate.

Flowers: Each composite flower is composed of 20-60 orange-yellow disc florets about ⅜-½" (9.5-12 mm) around, and rarely a few yellow rays, each ¹/₁₆-⅛" (2-3.5 mm) long. They are encompassed in 6-10 phyllaries, like a rosette of small leaves. The flowers look sort of scraggly and unimpressive to me. Flowers occur in groups of one or up to 12, appearing from late summer to early fall.

Fruits: The seeds or achenes are shaped like a narrow triangle, with two barbed fork tips that attach to fur or clothes. The seeds are also distributed by the wind.

Edibility: Cooked young leaves and stems are edible.

Medical: Infusions made from this species are used to treat several urinary tract problems, as well as to reduce recurrences of gout by increasing excretion of uric acid.

Flowers Composite flowers are 1-2" (2.5-5 cm) across, have up to 8 petals, though rarely the ray flowers are missing and only the tubular disk flowers are present. The flowers are sideways-facing, rather than upward-facing Each composite flower is composed of 20-60 orange-yellow disc florets about ⅜-½" (9.5-12 mm) around, and rarely a few yellow rays, each ¹/₁₆-⅛" (2-3.5 mm) long. They are encompassed in 6-10 phyllaries, like a rosette of small leaves. Flowers occur in groups of 1-12, appearing from late summer to early fall. Yellow flowers are 1½-2½" (3.8-6.3 cm) around, with 8 petals. Each is a composite flower. They bloom from July to October.
Leaves Opposite, and sessile or clasping—leaf bases wrap around the stem. Leaves are 1½-8" (4-20 cm) long × up to 1" (2.5 cm) wide, and simple (unlobed) Lower leaves are odd pinnate clusters on long petioles, in opposite pairs; upper leaves may be alternate. Leaves are up to 3" (7.6 cm) × 1" (2.5 cm), coarsely toothed, deltate or lanceolate. 1½-8" (3.8-20 cm) long, narrow, with coarse (dentate or serrate) teeth. They vary in shape from obovate or elliptic to lanceolate or linear
Fruit Fruits are brown, hard, and triangular in shape, with four barbed spears of roughly equal length called awns The seeds or achenes are shaped like a narrow triangle, with two barbed fork tips that attach to fur or clothes.
