Juttadinteria simpsonii is a species of succulent plant in the family Aizoaceae. It is a critically endangered species endemic to Namibia.
Juttadinteria simpsonii is known only from four subpopulations near Lüderitz in the ǁKaras Region of Namibia, 390–606 m (1,280–1,988 ft) above sea level, where it grows on granitic-gneiss ridges, sandy pockets amongst dolomite rocks, low and mid-elevation mountain slopes, and rocky or sandy plains. [1] [3] [4] 90% of the population occurs within the Namib-Naukluft National Park, with the other 10% found in the Tsau ǁKhaeb Sperrgebiet National Park. [1]
Juttadinteria simpsonii is an upright shrub growing to 250 mm (9.8 in) tall with up to 15 branches. The leaves are boat-shaped, with teeth along the margins, keels, and sometimes faces. The flowers, measuring 20–35 mm (0.79–1.38 in) across, each bear 40-60 white petals and 180–305 stamens. [3] [4]
Juttadinteria simpsonii is listed as critically endangered by the International Union for the Conservation of Nature under criteria A3d and A4ad, based on the decline of its population due to exploitation. Though the entire population falls within the boundaries of protected areas, it is frequently poached for the ornamental plant trade. A 2024 assessment for the IUCN Red List estimated that the population has declined by 60% since 2006, with a future decline of 80% expected by 2044. [1]
The Aizoaceae, or fig-marigold family, is a large family of dicotyledonous flowering plants containing 135 genera and about 1800 species. Several genera are commonly known as 'ice plants' or 'carpet weeds'. The Aizoaceae are also referred to as vygies in South Africa. Some of the unusual Southern African genera—such as Conophytum, Lithops, Titanopsis and Pleiospilos —resemble gemstones, rocks or pebbles, and are sometimes referred to as 'living stones' or 'mesembs'.

Aloe viridiflora is a species of plant in the genus Aloe. The species is endemic to Namibia with a wide range and is known from at least six different populations. Current trends are not known and the species is listed as LC on the IUCN Red List. However, it is scarce and Namibian authorities consider it threatened; the plant must not be removed or disturbed. It is the only known green-flowering aloe. Its natural habitats are dry savanna, subtropical or tropical dry shrubland, and rocky areas. It can produce hallucinations when ingested, leading to its occasional use in shamanic rituals.
Euphorbia tanaensis, commonly known as the Tana River euphorbia, is a critically endangered flowering plant within the family Euphorbiaceae. This species is endemic to a specific location along the Tana River in Kenya. Discovered initially as a group of nine specimens in 1988, a follow-up survey conducted in 2006 found only four remaining individuals, with no evidence of natural regeneration. The habitat of Euphorbia tanaensisis is under threat from ongoing deforestation.

It is one of the Lithops plants and shares the characteristic bi-leaf head pattern separated by a deep fissure, the bottom of which houses and protects the stunted stem.
