Drosera madagascariensis is a carnivorous plant of the Sundew genus (Drosera).
Drosera madagascariensis is a robust stem-forming species with a clearly visible stem, which stands upright in the case of younger plants and either uses its leaves to anchor itself to surrounding vegetation as it matures or bends over and forms a scrambling stem.
Drosera madagascariensis is native to the tropical Africa (Guinea, Nigeria, Cameroon, Congo, Angola, Zambesi, Tanganyika) as far south as South Africa and east to the island of Madagascar.
