It became the type species of Keetia after the original type species, Keetia transvaalensis, was made a synonym. This species is found down the southern African east coast in Malawi, Zimbabwe, Mozambique and South Africa. [1]

Leaves measure 5.5–13.5 × 3.5–6 cm, more or less lanceolate to ovate, acuminate apex, rounded to cordate at the base, often bullate, and glabrous to pubescent beneath. Acarodomatia present in the axils of the veins. Petioles are covered with crisped or patent hairs. Fruit 7–9 × 11–14 mm, somewhat oblong in profile, glabrous, black when ripe.

Rubiaceae Family of flowering plants including coffee, madder and bedstraw

The Rubiaceae are a family of flowering plants, commonly known as the coffee, madder, or bedstraw family. It consists of terrestrial trees, shrubs, lianas, or herbs that are recognizable by simple, opposite leaves with interpetiolar stipules and sympetalous actinomorphic flowers. The family contains about 13,500 species in about 620 genera, which makes it the fourth-largest angiosperm family. Rubiaceae has a cosmopolitan distribution; however, the largest species diversity is concentrated in the tropics and subtropics. Economically important genera include Coffea, the source of coffee, Cinchona, the source of the antimalarial alkaloid quinine, some dye plants, and ornamental cultivars.
