List of Rosales of South Africa

Last updated

Rosales is an order of flowering plants. [1] It is sister taxon to a clade consisting of Fagales and Cucurbitales. [2] The basal clade consists of the family Rosaceae; another clade consists of four families, including Rhamnaceae; and the third clade consists of the four urticalean families. [3] The order Rosales is strongly supported as monophyletic in phylogenetic analyses of DNA sequences. [4]

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. [5]

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. [6] 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. [7]

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)). [8]

Six 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.

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

Phylica is a genus of plants in the family Rhamnaceae. It contains about 150 species, the majority of which are restricted to South Africa, where they form part of the fynbos. A few species occur in other parts of southern Africa, and on islands including Madagascar, the Mascarene Islands, Île Amsterdam, Saint Helena, Tristan da Cunha, and Gough Island. The oldest fossils of the genus are of Phylica piloburmensis from the Burmese amber of Myanmar, dating to around 99 million years ago during the mid-Cretaceous.
