Luculia gratissima, copyright A. J. T. Johnsingh.

Belongs within: Gentianales.
Contains: CanthiumRandia, Rubioideae, Ixoroideae, Cinchonoideae.

The Rubiaceae are a cosmopolitan group of flowering plants usually bearing radial flowers with four-lobed corollas, often associated in tight cymes or clusters. Molecular phylogenies indicate a basal position within the family for Luculia, a genus of trees and shrubs found in the Himalayan region and southern China, characterised by red to pink or white moderate-sized flowers (calyx and corolla lobes up to two centimetres) and capsular, woody fruits. Coptosapelta is an eastern Asian genus of lianas and scandent shrubs bearing subglobose, woody capsular fruits with winged seeds.

Characters (from Hickman 1993): Annual, perennial, shrub, vine, or tree. Leaves generally opposite, entire; stipules generally on stalk, sometimes leaf-like (then leaves apparently whorled and stipules considered leaves), adjacent pairs sometimes fused. Inflorescence a cyme, panicle, cluster, or flower solitary, generally terminal and more or less axillary. Flower generally bisexual; calyx generally more or less four-lobed, sometimes absent; corolla generally radial, four-lobed; stamens epipetalous, alternate with corolla lobes, generally included; ovary generally inferior, chambers generally 2 or 4, style 1, more or less fused if 2. Fruit two or four nutlets or a berry, drupe, or capsule.
