Description: Information on this family and photographs of a number of species.
Flowering Plant Families, UH Botany The Apiaceae are mostly temperate herbs almost always with umbellate inflorescences comprising about 300 genera and 3,000 species that are commonly further distinguished by the presence of hollow stems and sheathing petioles. The leaves are nearly always alternate and pinnately or palmately compound or more than once compound; stipules are generally absent. The flowers are typically small, mostly bisexual, mostly actinomorphic except in a few instances where pseudanthia are produced and the peripheral flowers have enlarged petals directed away from the center of the inflorescence. The calyx is reduced to 5 tooth-like sepals around the summit of the ovary or may even be obsolete. The corolla consists of 5 distinct, typically inflexed petals or rarely is lacking. The androecium comprises 5 distinct stamens arising from an epigynous nectary disk. The gynoecium consists of a single compound pistil of 2 carpels, 2 styles borne on an enlarged stylopodium, and an inferior ovary with 2 locules, each containing a single pendulous, apical-axile ovule. The fruit is a schizocarp.
