Richard Spellenberg

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]


M. linearis (Pursh) Heimerl var. linearis

Stem ascending to erect, < 10 dm, glabrous to finely strigose

Inflorescence loosely forked; involucre cup-shaped, densely glandular-hairy, enlarged and papery in fruit; bracts 5, 6–10 mm in fruit, 1/2–2/3 fused; flowers generally 3 per involucre
Flower: perianth ± 10 mm, ± funnel-shaped, pale pink to magenta
Fruit ± 5 mm, club-shaped, wrinkled between the 5 ribs, hairy
Ecology: Riverbeds, railroads, roadsides, gravelly places
Elevation: < 300 m.
Bioregional distribution: South Coast (Orange, Riverside cos.)
Distribution outside California: native from Arizona to c US, Mexico
sometimes cultivated as ornamental
Synonyms: Oxybaphus l. (Pursh) B.L. Rob
