Flowering plants in the order Pandanales recorded from South Africa
Pandanales is anorder offlowering plants placed in themonocot clade in theAngiosperm Phylogeny Group andAngiosperm Phylogeny Web systems . Within the monocots Pandanales are grouped in thelilioid monocots where they are in asister group relationship with theDioscoreales . Historically the order has consisted of a number of differentfamilies in different systems but modern classification of the order is based primarily onmolecular phylogenetics despite diversemorphology which previously placed many of the families in other groupings based on apparent similarity. Members of the order have a subtropical distribution and includestrees ,shrubs ,vines , andherbaceous plants. The order consists of 5 families, 36 genera and about 1,610species .
Theanthophytes are a grouping of plant taxa bearing flower-like reproductive structures. They were formerly thought to be aclade comprising plants bearing flower-like structures. The group contained theangiosperms - the extant flowering plants, such asroses andgrasses - as well as theGnetales and the extinctBennettitales .[ 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] Ninebiomes have been described in South Africa:Fynbos , SucculentKaroo ,desert ,Nama Karoo ,grassland ,savanna ,Albany thickets , theIndian Ocean coastal belt , andforests .[ 3]
The 2018South African National Biodiversity Institute 'sNational Biodiversity Assessment plant checklist lists 35,130 taxa in the phylaAnthocerotophyta (hornworts (6)),Anthophyta (flowering plants (33534)),Bryophyta (mosses (685)),Cycadophyta (cycads (42)),Lycopodiophyta (Lycophytes(45)),Marchantiophyta (liverworts (376)),Pinophyta (conifers (33)), andPteridophyta (cryptogams (408)).[ 4]
Onefamily is represented in the literature. Listedtaxa includespecies ,subspecies ,varieties , andforms as recorded, some of which have subsequently been allocated to other taxa assynonyms , in which cases the accepted taxon is appended to the listing. Multiple entries under alternative names reflecttaxonomic revision over time.
