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). eFlora Treatment Author: Andy Murdock, except as noted Scientific Editor: Thomas J. Rosatti.
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. Etymology: (Greek: without closure, from absence of involucre) Note: Pollinated by hawkmoths. Selinocarpus moved to Acleisanthes. eFlora Treatment Author: Andy Murdock Reference: Poole 2003 FNANM 4:33--39
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.

MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
