Family: NyctaginaceaeView DescriptionDichotomous Key

Habit: 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.
Genera In Family: 30 genera, 350 species: warm regions, especially America; some ornamental (Bougainvillea; Mirabilis, four o'clock).

Habit: 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.

Species In Genus: 25 species: western North America. Etymology: (Greek: graceful) Note: 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.
