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 Am; some ornamental (Bougainvillea; Mirabilis, four o'clock). [Spellenberg 2003 FNANM 4:14–17] —Scientific Editor: Thomas J. Rosatti.
Annual, perennial herb.Key to Boerhavia
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.
± 40 species: warm regions worldwide. (H. Boerhaave, Dutch botanist, 1668–1738) [Spellenberg 2003 FNANM 4:17–28]
Perennial.
Stem: decumbent to erect, < 1 m, ± glabrous.
