Discophora Miers

Genus

Angiosperms > Aquifoliales > Stemonuraceae

Characteristics

Trees or shrubs; branches short strigose-pubescent or glabrate; bark smooth. Leaves alternate, entire. Inflorescences axillary, paniculate with strong branches at the base, the panicle diffuse, elongate and divaricate in fruit; pedicels strigose-pubescent, bracteate. Flowers polygamous or possibly unisexual; calyx short-campanulate, broadly and unevenly 5-lobed, the lobes deltoid or reduced to teeth; petals free, essentially glabrous, the apices inflexed with short mucros, the midrib prominent adaxially; stamens with fleshy flattened filaments bearing an adaxial swelling or appendage midway along its length, the appendage with clavate hairs, the filament abruptly narrowed below the versatile anthers, the anther sacs ovate, diverging at the base; pistil in staminate flowers abortive, cylin-drical or slightly conical, either immersed in a fleshy disc or eccentrically placed in the orifice of a hippocrepiform (U-shaped) disc, the ovary in functional pistil-late flowers cylindrical or angled and slightly compressed bearing a lateral basal fleshy avascular pulviniform appendage, the style not evident, the stigma capi-tate, occasionally broader than the ovary, the ovules 2, nearly collateral, pendant from the apex of the locule. Fruits drupaceous, flattened, slightly arcuate, bear-

Drupe oblong, flattened, slightly arcuate, ridged, sharply so on convex side, with a fleshy appendage on concave side; seed with copious endosperm, embryo minute.
ing a large oblong fleshy appendage of a lighter color on the concave side, the pericarp dark-pigmented, fleshy, the putamen with 2 pairs of equal primary ribs on the lateral edges of the fruit and 1 median ridge developed on both the con-cave and convex sides, the intermediate ridges more or less completely and prominently developed on the convex side; seed 1, embryo minute.
