Abstract
Several lines of evidence (morphological, karyological and molecular) support the exclusion of both
Sebaea madagascariensis
Klack. and
S. condensata
Klack. from
Sebaea
Sol. ex. R. Br. (Gentianaceae – Exaceae), resulting in the establishment of a new genus
Klackenbergia
Kissling and two new species combinations:
K. stricta
(Schinz) Kissling (=
S. madagascariensis
) and
K. condensata
(Klack.) Kissling.
Klackenbergia
is endemic to Madagascar and is morphologically recognized by its inflorescence with long bracts and bracteoles and subsessile flowers arranged in axillary fascicules at each node. Affinities with the other genera of the tribe Exaceae (
Exacum, Gentianothamnus, Ornichia, Sebaea, Tachiadenus
) are discussed.
