Abstract

On Kilimanjaro, Tanzania two rather different forms of Chlorophytum comosum were observed. One form occurred on higher altitudes, the other on lower altitudes. Morphological, molecular and ecological studies conclude that the two forms both are entitled to species recognition. The high altitude form must still be referred to C. comosum s.l., while the low altitude form is a new species and it is described as C. rhizopendulum Bjorå & Hemp sp. nov. The two species inhabit mutually completely exclusive habitats on Kilimanjaro. Whereas C. comosum has a wide ecological potential, C. rhizopendulum has narrow ecological demands as a highly adapted specialist. The two species are easily distinguished morphologically. Molecular studies show that C. comosum is of polyphyletic origin, and the species complex needs revision.
