A new species is added to the monotypic African genus Djinga. Djinga cheekii Ghogue, Huber & Rutish. (Podostemaceae) is described as a new species from Cameroon (Littoral Province) and its morphological affinities and conservation status are assessed. The main distinguishing characters are: stamens 2 (not 1 as in D. felicis ), flower buds inside spathella strongly inclined (not only slightly inclined as in D. felicis ), and stems lacking or only up to 6 mm long (not up to > 6 cm as in D. felicis ). A molecular analysis revealed that D. cheekii is sister to D. felicis , and both together are sister to Ledermanniella linearifolia and L. pusilla which show completely inverted flower buds inside the spathella, as typical for the large and still artificial genus Ledermanniella.
