Sebaea is a genus of annual plants in the family Gentianaceae. [1] Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand. [1] [2] The genus was paraphyletic and has been split in four genera: Exochaenium , Klackenbergia , Lagenias and Sebaeas.str.. [1] [3] [4] Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style [5] (called diplostigmaty [6] [7] ) and the shape of the testa cells of the seeds. [1]

The name honors Albertus Seba (1665–1736), a Dutch pharmacist, zoologist and collector. [8]

Gentianaceae is a family of flowering plants of 103 genera and about 1600 species.

<i>Exochaenium</i> Genus of flowering plants

The genus Exochaenium is endemic to sub-Saharan Africa, with species occurring in most tropical and sub-tropical regions of the continent, particularly on the Katanga plateau, with many extending to the Sudano-Zambesian and Guineo-Congolian regions. The genus is monophyletic and is used to study the variation and evolution of herkogamy.

<i>Klackenbergia</i> Genus of flowering plants

Klackenbergia is a genus of flowering plants belonging to the gentian family (Gentianaceae) and the tribe Exaceae. It only contains two species, both endemic to Madagascar. They are notable for their inflorescence with characteristic long bracts and bracteoles and sub-sessile flowers arranged in axillary fascicules at each node.

<span class="mw-page-title-main">Exaceae</span> Tribe of flowering plants

Exaceae is a flowering plant tribe in the family Gentianaceae. Exaceae comprises about 180 species assigned to eight monophyletic genera, with major centres of endemism in continental Africa, Madagascar and the southern tip of India and Sri Lanka (14 endemic species).

Diplostigmaty refers, in botany, to the presence of extra stigmas along the style. This condition is known from the genus Sebaea. It is thought to provide reproductive assurance.
