Perennial, shrub, tree, glabrous or hairy
Stem often forked
Leaves opposite, sessile or petioled, pairs generally unequal; blade generally entire
Inflorescence generally forked; of spikes, clusters, or umbels, each unit sometimes with a calyx-like involucre
Flower bisexual, radial; perianth of 1 whorl, petal-like, bell- to trumpet-shaped, base hardened, tightly surrounding ovary in fruit, lobes 4–5, generally notched to ± bilateral; stamens 1–many; ovary superior (appearing inferior because of hardened perianth base), style 1
Fruit: achene or nut, smooth, wrinkled, or ribbed
Genera in family: 30 genera, 300 species: warm regions, especially Am; some ornamental (Bougainvillea ; Mirabilis , four o'clock).
Perennial, subshrub
Stem repeatedly forked, decumbent to erect
Leaf generally petioled
Inflorescence forked; calyx-like involucres densely clustered or solitary in axils, bell- to saucer-shaped; flowers 1–16 per involucre, blooming sequentially
Flower: perianth funnel- to bell-shaped, lobes 5; stamens 3–5, generally exserted; stigma ± spheric, generally exserted
Fruit ± round to club-shaped, smooth to 5-ribbed; wing 0
Species in genus: ± 60 species: Am, Himalayas
Etymology: (Latin: wonderful)
Fls open in evening, close in morning. Spp. intergrade; Hermidium , Oxybaphus sometimes segregated, but intergrade with other species; careful study needed. [Pilz 1978 Madroño 25:113–132]
| Native |
Stem ascending to erect, < 8 dm, generally glandular-hairy
Leaf: blade 1–4 cm, ovate to ± reniform, glandular-hairy
Inflorescence: involucres clustered near ends of branches, bell-shaped; bracts 5, 5–6 mm, > 1/2 fused, lobes ovate; flower 1 per involucre
Flower: perianth 8–12 mm, widely funnel-shaped, white to pale pink (especially in w part of range)
Fruit ± 3 mm, ± spheric to ovoid, lightly dotted or wrinkled, glabrous
Ecology: Rocky places
Elevation: < 2300 m.
Bioregional distribution: White and Inyo Mountains, Desert
Distribution outside California: to Utah, Arizona, nw Mexico
Varieties intergrade, especially in e D. Poorly distinguished morphologically and geographically from M. californica; these may prove to be infraspecific entities in a more broadly conceived species
Recent taxonomic note: Mirabilis laevis (Benth.) Curran var. villosa (Kellogg) Spellenb.
| YOU CAN HELP US make sure that our distributional information is correct and current. If you know that a plant occurs in a wild, reproducing state in a Jepson bioregion NOT highlighted on the map, please contact us with that information. Please realize that we cannot incorporate range extensions without access to a voucher specimen, which should (ultimately) be deposited in an herbarium. You can send the pressed, dried collection (with complete locality information indicated) to us (e-mail us for details) or refer us to an accessioned herbarium specimen. Non-occurrence of a plant in an indicated area is difficult to document, but we will especially value your input on those types of possible errors (see automatic conversion of distribution data to maps). |
