Background: Ledebouria Roth (Hyacinthaceae: Hyacinthoideae) is a largely African genus with, more or less, 40 species occurring in South Africa. The species was first collected in December 1990 by R. Archer [Archer, R.H. 503 (PRE)] and remained un-identified. Subsequently, N. Hahn also collected the species in 1992 [N. Hahn 444 (ZPB)] and, upon failing to resolve the identity of the specimen, he approached A. Hankey who initiated further collaborative research.

Objective: To describe the new species of Ledebouria from Blouberg mountain massif in Limpopo Province, South Africa.

Method: Relevant existing specimens in herbaria were examined and morphological characters and states noted. The type specimen was collected during an expedition under the guidance of Prof. Dirk Bellstedt accompanied by Mr Adam Harrower.

Results: Ledebouria caesiomontana A.J.Hankey & N.Hahn sp. nov. was described and illustrated. The new species was distinguished from its closest relative, Ledebouria papillata S.Venter, by the ovary which lacks basal lobes, as well the absence of cataphylls and the irregular papillate ridges present only on the upper leaf surfaces.

Conclusion: Ledebouria caesiomontana is a new species restricted to the Blouberg mountain massif in Limpopo Province, South Africa. Initial estimates deem the species to be vulnerable (VU D2) as a result of especially anthropogenic-induced disturbances on the Blouberg.
