Annual, perennial herb, subshrub, [shrub, tree], glabrous or hairy. Stem: often forked. Leaf: opposite, sessile or petioled, pairs generally unequal; blade generally entire. Inflorescence: generally forked; spike, head-like cluster, or umbel, flowers rarely 1, bracts forming a calyx-like involucre or not. Flower: bisexual, generally ± radial (bilateral), sometimes cleistogamous in some genera; perianth of 1 whorl, generally petal-like, bell- to trumpet-shaped, base hardened, tightly surrounding ovary in fruit, lobes 3–5, generally notched to ± lobed; stamens 1–many; ovary superior (appearing inferior due to hardened perianth base), style 1. Fruit: achene in hardened perianth base; round to ± flat; smooth, angled, ribbed, or winged; glabrous, hairy, or glandular.
30 genera, 350 species: warm regions, especially America; some ornamental (Bougainvillea; Mirabilis, four o'clock). [Spellenberg 2003 FNANM 4:14–17] —Scientific Editor: Thomas J. Rosatti.
Key to Nyctaginaceae
Annual, perennial herb. Stem: prostrate to erect; internode often with sticky region. Leaf: petioled; blade 1–6 cm, paler beneath, often brown-dotted. Inflorescence: panicle-like, branches ending in umbel, spike-like raceme, or paired or solitary flowers; bracts 1–3, free, not forming involucre. Flower: closing by evening; perianth bell-shaped, tube < 5 mm, limb < 3 mm; stamens 1–5; stigma ± spheric, generally exserted. Fruit: < 4 mm, club-shaped; ribs 4–5; wings 0.Key to Boerhavia
