Family Portulacaceae

Herbs annual or perennial , rarely ± shrubby, usually succulent, usually glabrous except for nodal hairs and/or scales . Leaves alternate or opposite; true stipules absent, nodes sometimes with axillary scales and/or hairs; petiole usually poorly defined or absent; leaf blade simple , usually fleshy , margin entire. Inflorescences usually terminal , less often axillary , in cymes or racemelike panicles, forming heads of sessile flowers surrounded by an involucre of leaves, or reduced to solitary flowers. Bracts inconspicuous. Flowers bisexual , very rarely unisexual , actinomorphic . Sepals 2, free or basally connate , herbaceous or scarious . Petals 4-6 or seldom more, distinct or basally connate, imbricate, often brightly colored , usually short lived. Disk usually absent. Stamens 4-100, free, fascicled, or adnate to petals; filaments linear ; anthers 2-loculed, introrse , dehiscence longitudinal . Ovary superior or half-inferior, 1-loculed, 2-5-carpellate; ovules 1 to many, campylotropous; placentation basal or free-central . Style linear; stigma 2-9-lobed. Fruit a thin-walled capsule, circumscissile or 2- or 3-valved, rarely a nut, often globose or subglobose, smooth . Seeds many, reniform or globose, caruncle present or not; endosperm mostly copious , surrounded by embryo.

About 19 genera and 500 species: mainly in more arid regions of S hemisphere, especially Africa, South America, and Australia, fewer species in Asia, Europe, and North America; two genera (one introduced ) and six species (two endemic, two introduced) in China.[1]

Genus Portulaca

Herbs, annual (perennial in P. suffrutescens). Roots tuberous , fleshy , fibrous , or small taproots . Stems erect to prostrate , branched, fleshy or suffrutescent ; trichomes in inflorescence or stem nodes absent or present, glabrous otherwise. Leaves alternate or subopposite, congested and involucrelike immediately proximal to inflorescence; blade terete , subterete, or flattened. Inflorescences terminal in clusters , or axillary on short branches. Flowers sessile or subsessile , usually open only in sunshine; sepals broadly clasping at base , herbaceous to scarious , falling from top of capsule; petals ephemeral , 5-7, usually distinct , margins usually entire; stamens (4-) 6-40(-100) ; ovary half inferior to inferior, plurilocular proximally to 1-locular distally, placentation free-central ; style 1, short, stigmas 3-8(-18). Capsules membranaceous , chartaceous , dehiscence circumscissile. Seeds many, brown to black or gray, reniform to cochleate; seed coat smooth or variously sculptured , granular to stellate-tuberculate or spiny . x = 4, 5, 8, 9.

Species 100-125: nearly worldwide, primarily tropical and subtropical , also temperate .[2]
