Volubilis, caule flagelliforme, foliis ovali-ovatis acutis uninerviis glabris ; inflorescentia parva axillari breviter dichotome ramosa, floribus pluribus dense glome- ratis ; pedicellis brevibus, calyce breviter campanulato sparse pilo- siilo, segmentis late ovalibus vel ovatis clliolatis, glandulis parvis singulis linearibiis interpositis ; corolla campanulata, lobis brevibus rotundatis emarginatis, tubo pilis albidis erectis ore instructis, et infra setis numerosis refiexis cum staminibus alternantibus indutis ; coronse squamis antlieris adnatis, parte tantum superiori libera membranacea anguste triangulari, ab antherae appendice latiori superata ; polliiiiis filiformibus, caudiculis latis membranaceis. Hab. Eabai Hills, East Tropical Africa, July-Sept. 1885, W. E. Taylor. The leaves are 4 in. long by scarcely 2 in. broad, and have an entire obtuse base ; the petioles f in. long. The whole inflorescence is only ^-f in. in length, the peduncles being 3-4 lines, and the closely crowded pedicels borne on its short branches, 1-1^ lines. The calyx- segments are |-1 line long ; the corolla is 2 lines long, its lobes only f line ; the mouth of the tube is filled with a ring of stiffish hairs, while the interior of the tube at the level of the stamens bears tufts of downwardly pointing shorter but otherwise similar hairs. The corona-scales, except for the short (less than ^ line) acute tip, are adnate to the backs of the anthers, the broader triangular appendage of which overtops them; the stamens are 1 line long, with coherent filaments. Is near the Indo-Malayan and Chinese species M. tinctoria Br., but is distinguished by its inflorescence, larger flowers, and leaves with a marked obtusely pointed base.
