Anubias gigantea Chevalier ex Hutchinson

Anubias gigantea is a species belonging to the Aroid genus Anubias. It was first mentioned by Auguste Chevalier in 1920, based on material that he had collected in Guinea. The formal description followed in 1939 by John Hutchinson. It is closely related to A. afzelii, basically only differing from that species by the form of the leaf-blade.

The following names are synonyms of A. gigantea: A. gigantea var. tripartita Chevalier, 1920 and A. hastifolia var. robusta Engler, 1915.

A. gigantea is known from West Africa, including the countries of Guinea, Sierra Leone, Liberia, Ivory Coast, and Togo.

A. gigantea has large arrow-shaped leave blades that can be up to 30 cm (12 in) long and 14 cm (6 in) wide. The leaf stems are slightly shorter till up to 2.5 times longer than the blade. The leaves are set on a creeping and rooting rhizome that is 1–3 cm thick. The spathe is 3.5–8 centimetres (1.4–3.1 in) long and has a 14–60 centimetres (5.5–23.6 in) long peduncle. The spadix is up to 9 centimetres (3.5 in) long and slightly longer than the spathe, so that the tip slightly protrudes from it. The upper part is covered with male flowers, of which the 4-6 stamens are fused into , with the thecae on its sides. The lower part of the spadix is covered with female flowers that are reduced to the ovary and stigma.
