    Distribution
    Mucuna poggei occurs in Angola, Burundi, the Democratic Republic of Congo, Kenya, Mozambique, Tanzania and Uganda (Map 1). Hepper (1956) reported this species to occur in Zambia, but we have seen no specimens from that country.
    Ecology
    The species occurs in gallery, riverine, and evergreen forest, on valley slopes and along rivers; one collection from Uganda is reported from grassland.
    Note

    In the protologue of Mucunarubro-aurantiaca De Wild. the author did not state the herbarium in which the type material is housed. Nevertheless, in the Meise Herbarium (BR) we located two sheets of Homblé 664. On one of these (BR 894583) is written ‘holotype’ by hand in pencil. We agree with Hepper (1956) who placed M. rubro-aurantiaca as a synonym of M. poggei Taub.

    Mucuna poggei is easily recognised by the indehiscent fruit, the length of the flowers (7.5 – 8.5 cm long) and of the stipels (5 – 6 mm long), and the long, dense, appressed hairs on the abaxial surface of the leaflets. For differences from the other taxa see comments under M. pesa and M. occidentalis.

    In the protologue of Mucuna poggeia number of syntypes are cited: Angola, Welwitsch 2240 – 2241; Malandsche, an einem Bache Pogge 831; OberesCongogebiet, an flusseLuatschim, Lourenço Marques 279; Togo, Bismarckburg, am WegenachKatschenkiButtner 4; Nʼdongo a Mʼjoi, (nachLourenço Marques). Hepper (1956) commented that Pogge 831 and Buttner 4 were apparently destroyed at Berlin. He designated the specimen Welwitsch 2241 (BM) as an isolectotype of M. poggei var. poggei, but gave no indication as to the herbarium in which the lectotype is deposited, although Welwitschʼs top set of specimens is housed in COI and it is likely that the lectotype is deposited there.
