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.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
