Overview

General Description

Shrubs erect or scandent, 0.4-3 m. Branchlets 4-angled, twisted, glabrous to pubescent. Leaves alternate, compound or simple; petiole 2-10 mm; leaflets 3-7, terminal petiolule 2-12 mm, lateral ones subsessile; leaf and leaflet blades ovate to elliptic, rarely obovate or suborbicular, 0.7-4 cm long, 0.5-2 cm wide, adaxially shiny, drying rugose, glabrous, sometimes puberulent along midrib, to densely villous, abaxially glabrous to sparsely to densely villous, base cuneate or rounded, apex acute, rarely blunt; veins obscure. Cymes terminal, 3-25-flowered; bracts subulate, 3-7 mm. Pedicel 0-2 cm. Calyx with 5 raised ribs, glabrous to sparsely pubescent; tube 1-2 mm; lobes subulate-linear, 1-3 mm. Corolla yellow, nearly funnelform; tube 0.9-1.5 cm; lobes ovate or oblong, 4-8 mm, often acute at apex. Berry ripening black, globose, 5-10 mm in diameter.

Evolution

Phylogeny of Oleaceae were assessed by a cladistic analysis of DNA sequences from two noncoding chloroplast loci, the rps16 intron and the trnL-F region (Wallander and Albert, 2000). Results indicated that the Tribe Jasmineae is monophyletic, but Jasminum is paraphyletic with Menodora nested within it, as Kim and Jansen (1993) and Rohwer (1996) have suggested.
