Flowering plants in the order Gentianales recorded from South Africa
The Gentianales are an order of flowering plants , included within the asterid clade of eudicots . It comprises more than 16,000 species in about 1,138 genera in 5 families.[ 1] More than 80% of the species in this order belong to the family Rubiaceae .
The anthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be a clade comprising plants bearing flower-like structures. The group contained the angiosperms - the extant flowering plants, such as roses and grasses - as well as the Gnetales and the extinct Bennettitales .[ 2]
23,420 species of vascular plant have been recorded in South Africa, making it the sixth most species-rich country in the world and the most species-rich country on the African continent. Of these, 153 species are considered to be threatened.[ 3] Nine biomes have been described in South Africa: Fynbos , Succulent Karoo , desert , Nama Karoo , grassland , savanna , Albany thickets , the Indian Ocean coastal belt , and forests .[ 4]
The 2018 South African National Biodiversity Institute 's National Biodiversity Assessment plant checklist lists 35,130 taxa in the phyla Anthocerotophyta (hornworts (6)), Anthophyta (flowering plants (33534)), Bryophyta (mosses (685)), Cycadophyta (cycads (42)), Lycopodiophyta (Lycophytes(45)), Marchantiophyta (liverworts (376)), Pinophyta (conifers (33)), and Pteridophyta (cryptogams (408)).[ 5]
Five families are represented in the literature. Listed taxa include species , subspecies , varieties , and forms as recorded, some of which have subsequently been allocated to other taxa as synonyms , in which cases the accepted taxon is appended to the listing. Multiple entries under alternative names reflect taxonomic revision over time.
Family: Apocynaceae ,[ 5] 112 genera have been recorded. Not all are necessarily currently accepted.
