Higher Taxonomy
Family: NyctaginaceaeView DescriptionDichotomous Key

Common Name: FOUR O'CLOCK FAMILY
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).

Genus: AcleisanthesView DescriptionDichotomous Key

Common Name: TRUMPETS
Habit: Perennial herb from thick taproot, minutely hairy. Stem: prostrate to ascending. Leaf: petioled; blade < 8 cm, +- firm to fleshy, paired leaves +- unequal. Inflorescence: bracts 1--3, free, not forming involucre; flower generally 1, or paired. Flower: nocturnal or cleistogamous; perianth trumpet-shaped, white, tube slender; stamens 5, +- exserted; stigma +- spheric, +- exceeding anthers. Fruit: oblong, glabrous; wings translucent or 0.
Species In Genus: 17 species: especially southwestern United States, northeastern Mexico. Etymology: (Greek: without closure, from absence of involucre) Note: Pollinated by hawkmoths. Selinocarpus moved to Acleisanthes.

Acleisanthes nevadensis (Standl.) B.L. Turner
NATIVE
Habit: Annual; hairs appressed and divergent, white, also glandular-puberulent. Stem: prostrate to erect, < 3 dm. Leaf: petiole 5--20(26) mm; blade ovate to round. Flower: perianth tube +- green, limb white. Fruit: 5--7 mm; wings 2 mm.
Ecology: Dry, rocky areas; Elevation: 1250 m. Bioregional Distribution: DMtns (ne Kingston Range, se Inyo Co.); Distribution Outside California: to southwestern Utah, northwestern Arizona. Flowering Time: Jun--Sep
Synonyms: Selinocarpus diffusus A. Gray subsp. nevadensis Standl.; Selinocarpus nevadensis (Standl.) B.A. Fowler & B.L. Turner
Unabridged Note: Closely related to Acleisanthes diffusa (A. Gray) R.A. Levin (southwestern United States except California), from which it differs in leaf morphology, perianth size, geog, and (reportedly) ecology.
