Leaf: simple, alternate or opposite, linear, obovate, spoon-shaped, [elliptic, ± round], flat or cylindric, hairs in axils, inconspicuous or not , upper 2–5 forming involucre. Inflorescence: flowers 1 or clustered at stem tips. Flower: bisexual, radial; sepals 2, fused at base, lower part fused to ovary and generally persistent in fruit; petals 5, fused at base, forming ring, yellow [magenta, rose, orange, white]; stamens 4–20[> 20], epipetalous or not, anthers yellow; ovary 1/2-inferior, chamber 1, ovules several to many, placenta free-central; style branches 3–6. Fruit: capsule, circumscissile. Seed: many, reniform, ± tubercled, black, gray, [brown, ± blue].
1 genus, ± 100 species: ± worldwide, especially tropics, subtropics some cultivated (Portulaca grandiflora Hook.; Portulaca umbraticola Kunth). [Nyffeler & Eggli 2010 Taxon 59:227–240] All other California genera previously in this family now in Montiaceae. —Scientific Editor: Thomas J. Rosatti.

Annual, ± perennial herb. Stem: spreading, 3–40 cm. Leaf: 3–30 mm. Inflorescence: flowers 1–8. Flower: sepals 2.5–5 mm, green or ± red; petals 3–5 mm, yellow; stamens 5–12; style branches 3–6. Fruit: 2–4.5 mm wide. Seed: 0.6–1 mm wide, dark brown to black.
2n=18,36,54. Disturbed soil; < 2100 m. California; probably native to eastern hemisphere, widely naturalized elsewhere. Apr–Oct [Online Interchange]
Unabridged note: Evidence indicates that Portulaca oleracea is not monophyletic. Some specimens found in Mojave Desert seem to belong to either Portulaca oleracea subsp. impolita Danin & H.G. Baker or to a lineage more close related to Portulaca johnstonii Henrickson; study needed.
