Mirabilis greenei S. Wats.

Mirabilis greenei may have as many as sixteen flowers per involucral bract.

Herbs, forming hemispheric clumps 6-8 dm diam., glabrous to sparsely puberulent. Stems 4-8 dm. Leaves spreading; petioles of proximal leaves 1-2.7 cm; blades of midstem leaves widely elliptic to ovate, 3-8-5 × 3-5.5 cm, base obtuse, often asymmetric, apex acute or acuminate. Involucres: peduncle 25-85 mm; involucres erect or ascending, 26-40 mm; bracts 5, 50% connate, apex acute to widely ovate. Flowers 6(-16) per involucre; perianth magenta, funnelform, 4-5 cm. Fruits light brown, with 5 blunt angles and 10 slender ribs visible when wet, widely obovoid to widely ellipsoid, 7-7.5 mm, tuberculate, glabrous or very sparsely puberulent, secreting mucilage most abundantly on ribs when wetted. 2n = 66.

Plants erect or ascending, 4-6 dm. high, sparsely branched, glabrous throughout or sparsely and obscurely puberulent on the young peduncles, the branches stout, grayish-green; petioles stout, 0.4^3 cm. long; leaf-blades rhombic-orbicular, orbicular-ovate, or oblong-ovate, 4.5-7.5 cm. long, 2.5-6.5 cm. wide, broadly rounded to obtuse at the base and usually shortdecurrent, acute or obtuse to broadly rounded at the apex, thick and succulent, glaucescent; peduncles axillary or in terminal cymes, 1-5.5 cm. long, stout, the leaves of the inflorescence much reduced and bractlike, often deciduous; involucre campanulate, 2.5-4.5 cm. long, green or tinged with red, the 5 lobes equaling or shorter than the tube, broadly ovate or oval, obtuse to acute, usually abruptly apiculate; perianth 3.5-5 "cm. long, purplish-red, glabrous, the tube 5-6 mm. in diameter, abruptly expanded into a shallowly 5-lobed limb 2.5-3 cm. broad; stamens equaling the perianth; fruit obovoid-oblong, 5 mm. long, nearly black, 5-angulate, rugulose, obscurely puberulent or glabrate.
Type locality : Mountain sides about Yreka, California.
Distribution: In dry soil, northern California from Tehama County to Siskiyou County.
