Flowering plants in the order Pandanales recorded from South Africa
Pandanales is an
order of
flowering plants placed in the
monocot
clade in the
Angiosperm Phylogeny Group and
Angiosperm Phylogeny Web
systems . Within the monocots Pandanales are grouped in the
lilioid monocots where they are in a
sister group relationship with the
Dioscoreales . Historically the order has consisted of a number of different
families in different systems but modern classification of the order is based primarily on
molecular phylogenetics despite diverse
morphology which previously placed many of the families in other groupings based on apparent similarity. Members of the order have a subtropical distribution and includes
trees ,
shrubs ,
vines , and
herbaceous plants. The order consists of 5 families, 36 genera and about 1,610
species .
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 .
[1]
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.
[2] 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 .

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)).

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.
