Ornichia is a plant genus in the gentian family (Gentianaceae), tribe Exaceae. [1] [2] The genus is endemic to Madagascar. [3]
Three species are accepted: [3]
Gentianales is an order of flowering plants, included within the asterid clade of eudicots. It comprises more than 20,000 species in about 1,200 genera in 5 families. More than 80% of the species in this order belong to the family Rubiaceae.
Gentianaceae is a family of flowering plants of 103 genera and about 1600 species.
Anthocleista is a genus of tree- and shrub-like tropical plants in the gentian family, tribe Potalieae, subtribe Potaliinae. There are about 50 species in the genus, native mainly to tropical Africa, including Madagascar and the Mascarene Islands. Anthocleista was once placed in the family Loganiaceae, but more recent molecular, morphological, and phytochemical evidence has placed the group well within the Gentianaceae.
Chuniophoenix is a genus of palm tree named after Chun Woon-Young, then director of the Botanical Institute, Sun Yat Sen University, Guangzhou. It contains three known species, native to southern China and Vietnam. Chuniophoenix is a member of tribe Chuniophoeniceae, a small group of palms that exhibit great morphological diversity and interesting biogeography. The tribe includes four genera: Chuniophoenix with 3 species in China and Vietnam, Kerriodoxa (monotypic) in Peninsular Malaysia and Thailand, Nannorrhops (monotypic) from Arabia to Afghanistan, and Tahina (monotypic) in Madagascar.
Exacum is a genus of plant in family Gentianaceae. It contains the following species :
Pyrostria is a genus of dioecious flowering plants in the family Rubiaceae. Most of the species are endemic to Madagascar, others occur on islands in the western Indian Ocean, a few are found in continental Africa, and only six species occur in tropical Southeast Asia. The formerly recognized genus Leroya, containing two species endemic to Madagascar, L. madagascariensis and L. richardiae, was sunk into synonymy with Pyrostria.
Sebaea is a genus of annual plants in the family Gentianaceae. Species occur in Africa, Madagascar, India, China, Thailand, Australia and New Zealand. The genus was paraphyletic and has been split in four genera: Exochaenium, Klackenbergia, Lagenias and Sebaeas.str.. Synapomorphies for Sebaea s.str. include the presence of extra stigma along the style and the shape of the testa cells of the seeds.
Secamonopsis microphylla is a plant species endemic to southern Madagascar. It is a trailing or erect herb up to 1.5 m tall. Leaves are narrowly oblong, up to 10 mm long. Flowers in groups of 1–3, yellow, tubular, up to 1.2 mm long.
Pentopetia is a plant genus in the family Apocynaceae, first described as a genus in 1844.
Pervillaea is a genus of plants in the family Apocynaceae, first described as a genus in 1844. It is native to Mauritius and Madagascar in the Indian Ocean.
Calyptranthera is a genus of plants in the family Apocynaceae, first described as a genus in 1996. The entire genus is endemic to Madagascar in the Indian Ocean.
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.
The monotypic genus Lagenias is endemic to the Cape Province of South Africa . It belongs to the tribe Exaceae of the Gentianaceae.
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.
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).
Tachiadenus is a plant genus in the gentian family (Gentianaceae), tribe Exaceae. It contains 12 species.
Gentianothamnus is a monotypic plant genus in the gentian family (Gentianaceae), tribe Exaceae. The sole species is Gentianothamnus madagascariensis. It is endemic to Madagascar.
Chuniophoeniceae is a tribe of palms in subfamily Coryphoideae of plant family Arecaceae. The four genera within the tribe are morphologically dissimilar and do not have overlapping distributions. Three of the genera are monotypic, while the fourth genus (Chuniophoenix) has three species.
Utania is a genus of flowering plants belonging to the gentian family (Gentianaceae), the tribe Potalieae, and the subtribe Potaliinae. A small genus it has 12 species.
Baroniella is a genus of flowering plants belonging to the family Apocynaceae.
