List of Boraginales of South Africa

Last updated

Boraginales is a valid taxonomic name at the rank of order for a group of flowering plants. It includes Boraginaceae and closely related asterid families. The Boraginales include about 125 genera, 2,700 species and its herbs, shrubs, trees and lianas (vines) have a worldwide distribution. In the 2016 APG IV system Boraginales is an order with only one family Boraginaceae, which includes the former family Codonaceae. At the time of the APG IV consensus there was insufficient support to divide this monophyletic group further. [1]

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]

One family is 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.

Boraginaceae Family of flowering plants

Boraginaceae, the borage or forget-me-notfamily, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution.

<i>Cynoglossum</i> Genus of flowering plants in the borage family Boraginaceae

Cynoglossum is a genus of small-flowered plants in the family Boraginaceae.

Boraginoideae Subfamily of plants within the borage family (Boraginaceae)

Boraginoideae is a subfamily of the flowering plant family Boraginaceae s.s, with about 42 genera. That family is defined in a much broader sense in the Angiosperm Phylogeny Group (APG) system of classification for flowering plants. The APG has not specified any subfamilial structure within Boraginaceae s.l.

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

Lobostemon is a genus of flowering plants belonging to the family Boraginaceae. Its native range is South Africa. The majority of species are limited to the winter rainfall area of the country, from Springbok to Mossel Bay. In Afrikaans these species are known as agtdaegeneesbos, or loosely translated, bush that will heal in eight days. As this name suggests, many species have medicinal properties. This is best known from Lobostemon fruticosus, which is used for treating wounds, blood poisoning, ringworm, skin diseases and syphilis.
