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, generally glandular. Stem: prostrate to ascending, generally ± red. Leaf: generally fleshy, petioled. Inflorescence: head or umbel; flowers maturing outer before inner or ± simultaneously; receptacle conic, ± smooth; bracts 5–10. Flower: perianth salverform to trumpet-shaped, generally fragrant, lobes 4–5; stamens 4–5, included; stigma linear, included. Fruit: body fusiform; wings (0)2–5, lobe-like, prominent, opaque, thick, not continuous above fruit body.Key to Abronia
25 species: western North America. (Greek: graceful) [Galloway 2003 FNANM 4:61–69] Closely related to Tripterocalyx; relationships among species Abronia gracilis Benth. (Mexico), Abronia maritima, Abronia umbellata, and Abronia villosa need study; hybrids involve Abronia latifolia, Abronia maritima, Abronia umbellata; Abronia gracilis included in TJM (1993) based on misidentifications.
Perennial herb, fleshy, finely glandular-hairy; root deep, thick. Stem: prostrate, < 2 m; branches short, forming a dense mat. Leaf: petiole 1–6 cm; blade 2–5 cm, broadly ovate to reniform, thick. Inflorescence: peduncle 1–6 cm; bracts 5–9 mm, ovate; flowers 17–34. Flower: perianth tube 9–12 mm, yellow to ± green, limb 8–13 mm wide, yellow. Fruit: 8–15 mm, net-veined, glabrous or ± hairy, tapered to base, tip; wings 0 or 5.
Coastal dunes, scrub; < 100 m. North Coast, Central Coast, n South Coast (Santa Barbara Co.); to British Columbia. May–Oct [Online Interchange]
