Description
Family Rubiaceae
The Rubiaceae are trees , shrubs , or infrequently herbs comprising about 450 genera and 6,500 species, including some lianous forms. The leaves are simple and usually entire, and are opposite or sometimes whorled ; stipules are present and interpetiolar . The flowers are nearly always bisexual and actinomorphic , often heterostylous, and usually are in cymose inflorescences. The calyx is mostly somewhat reduced and 4-5-lobed or sometimes the lobes are obsolete or rarely one of them greatly expanded and brightly colored . The sympetalous corolla is mostly 4-5-lobed, occasionally with 3 or up to 10 lobes. The androecium consists of as many stamens as corolla lobes and is adnate to the corolla tube or epigynous zone, alternate with the lobes. The gynoecium consists of a single compound pistil of 2 or seldom more carpels, a single style, and a nearly always inferior ovary with the number of locules equaling the number of carpels, each with 1-many axile ovules. An epigynous nectary disk is usually present. The fruit is variable, sometimes forming multiples . -- Gerald Carr.
