Djinga cheekii sp. nov. (Podostemaceae) from Cameroon

چکیده
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 affi nities and conservation status are assessed. Th e main distinguishing characters are: stamens 2 (not 1 as in D. felicis ), fl ower 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 fl ower buds inside the spathella, as typical for the large and still artifi cial genus Ledermanniella.
