25. Leavenworthia Torr.

(Rollins, 1963)

Plants annual, terrestrial, glabrous. Leaves all or nearly all basal and forming rosettes, petiolate, the blades pinnately lobed, the margins otherwise entire to minutely toothed or wavy, the terminal lobe distinctly or slightly larger than the 2–10 pairs of lateral lobes. Inflorescences usually of solitary, long-stalked flowers arising from the rosette leaves, rarely a short, reduced, few-flowered raceme with long-stalked flowers. Sepals narrowly oblong, spreading or erect. Petals unlobed or distinctly notched at the apex, white, yellow, or lavender toward the tip and yellow to orange toward the base. Styles 1.5–5.0 mm long, unlobed. Fruits linear or narrowly oblong (elliptic or nearly circular in outline elsewhere), more than 10 times (1 or 2 times elsewhere) as long as wide, flattened (circular in cross-section elsewhere), somewhat fleshy, dehiscent longitudinally. Seeds in 1 row in each locule, circular, flattened, broadly winged all around or nearly wingless, the surface with a prominent honeycomb-like pattern, reddish brown. Eight species, southeastern U.S.
