    [O-EM]
    General Description

    Terrestrial herbs with tuberous roots. Stem leafy, elongate. Leaves usually narrow, lanceolate, acute, scattered along the stem, not clustered. Inflorescence terminal, sparsely to densely many- flowered . Flowers resupinate, green; sepals and petals free. Sepals entire, the laterals spreading. Petals simple but often toothed or irregular. Labellum free, often a uriculate at base, three-lobed (rarely entire), with cylindrical spur. Column erect, the anther loculi divergent, separated by a broad connective; canals hardly developed; pollinaria two, each with a sectile pollinium, long caudicle and small viscidium; stigmatic processes each two-lobed with one lobe projecting down in front of the labellum base, the other lobe upright in front of the anther connective; rostellum three-lobed, mid- lobe low, rounded or emarginate, adnate to the connective; side lobes spreading, narrowed toward apex. (PC).

    Ecology

    Species of Roeperocharis are inhabitants of montane grassland at elevations up to 2440 m. Roeperocharis bennettiana Rchb.f. is a robust member of the genus growing up to 100 cm tall, specimens of which have been collected from Nyika National Park in Zambia and Malawi at 2200 m. It tends to grow in drier areas, but other congeneric orchids are usually found in bogs and other wet areas (e.g. R. wentzeliana Kranzl.). Roeperocharis flower in March and April in south-central Africa (la Croix and Cribb, 1995). (RN).

    Distribution

    A genus of five species in eastern Africa, from Ethiopia to Malawi and also in Cameroon. (PC).
