Palisota is a genus of flowering plants in the family Commelinaceae (the spiderwort family), placed in the order Commelinales. The genus was first described in 1828 and contains roughly 20–25 species. It belongs to the monocot clade and shares the family's characteristic boat-shaped spathes and fleshy, often brightly coloured berries that distinguish it from most other Commelinaceae genera.
All members of the genus are native to sub-Saharan Africa, where they occupy the understorey of tropical rainforests. Species are distributed mainly across western and central Africa — from Nigeria and Cameroon through Gabon, the Congo Basin, and the Democratic Republic of Congo — with a few species reaching East Africa (Tanzania) and southern Africa (Angola, Zambia). Palisota bracteosa has naturalised in Trinidad & Tobago, the only member recorded outside Africa. Plants grow as robust, clumping herbs with large, often glossy leaves and produce dense racemes or panicles of small white or pale flowers followed by persistent red or orange berries.
Notable species include Palisota hirsuta, one of the most widespread members across western and central Africa, and Palisota barteri, a frequently cultivated ornamental recognised by its bold foliage. Several species, including Palisota lagopus and Palisota bogneri, have restricted ranges within central African forest blocks.
Distribution
Palisota is endemic to sub-Saharan Africa, with its centre of diversity in the tropical rainforests of western and central Africa, including Cameroon, Gabon, the Republic of Congo, and the Democratic Republic of Congo. A handful of species extend to East Africa (Tanzania) and southern Africa (Angola, Zambia), and Palisota bracteosa has naturalised in Trinidad & Tobago.
Taxonomy Notes
The genus was first described in 1828 and is placed in the family Commelinaceae, order Commelinales (per GBIF). It is the only genus within Commelinaceae bearing fleshy, berry-like fruits — a trait that sets it apart from close relatives such as Commelina and Tradescantia.
