Disc ring-shaped or not. Ovary superior or rarely semi-inferior, (1- or) 2(--4) -locular, placentation axillary or parietal; ovules 1 to many per locule.

Anthocleista is a genus of tree- and shrub-like tropical gentians in the Gentian family (Gentianaceae), tribe , subtribe Potaliinae. There are about 50 species in the genus Anthocleista, native mainly to tropical Africa, Madagascar and the Mascarene Islands. Anthocleista was once placed under the family Loganiaceae, but more recent molecular, morphological, and phytochemical evidence has placed the group well within the Gentianaceae. [more]
Buddleja, or Buddleia () but commonly known as the Butterfly Bush, is a genus of flowering plants. The generic name bestowed by Linnaeus posthumously honoured the Reverend Adam Buddle (1662?1715), a botanist and rector in Essex, England, at the suggestion of Dr William Houstoun. Houstoun sent the first plants to become known to science as buddleja (B. americana) to England from the Caribbean about 15 years after Buddle's death. [more]
Shrubs, scandent, mostly climbing or creeping. Branchlets terete, sometimes with 4 faint ridges. Leaves opposite, petiolate, connected by interpetiolar stipular rims; leaf blade margin entire.

Calyx small, deeply lobed; lobes imbricate, connate, inside with colleters at base. Corolla rotate to subcampanulate; tube thin, fleshy; lobes thin to thick, fleshy, valvate in bud. Stamens exserted; filaments very short, flat; anthers 2- or 4-locular, connate or free, base 2-parted, introrse. Ovary small, 2-locular, with 1--4 ovules per locule. Style mostly long, slender; stigma capitate or 2-cleft. Berries red, globose, 1-seeded or more. Seeds ellipsoid to orbicular, concave on hilar side but convex on other side; seed coat thin; embryo tiny, almost cylindrical; endosperm thick, horny. [more]
