Higher Classification | Dicotyledons |
Family | MALVACEAE |
Synonyms | Malva asperrima Eckl. & Zeyh. (later homonym), not of Jacq. (1797), Malvastrum dissectum Harv., Malveopsis dissecta (Harv.) Kuntze |
National Status |
Status and Criteria | Critically Endangered B2ab(iii,v); C2a(i) |
Assessment Date | 2019/02/21 |
Assessor(s) | D. Raimondo & N.A. Helme |
Justification | This species has an extent of occurrence (EOO) of less than 1600 km² and an area of occupancy (AOO) of less than 10 km². Five small, severely fragmented subpopulations each consisting of fewer than 50 plants remain after more than 70% of the habitat has been transformed for crop cultivation. The total population of this palatable species is suspected to be fewer than 250 plants and it continues to decline due to overgrazing. It is therefore assessed as Critically Endangered under criteria B and C. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | It occurs from Bredasdorp to Kogmanskloof and Potberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Montagu Shale Renosterveld, Potberg Sandstone Fynbos, De Hoop Limestone Fynbos, Potberg Ferricrete Fynbos, Elim Ferricrete Fynbos, Albertinia Sand Fynbos, Agulhas Sand Fynbos, Cape Lowland Alluvial Vegetation |
Description | Plants grow in shale, clay soil. |
Threats |
Agriculture is a past, severe threat and more than 70% of its habitat was ploughed between 1940 and 1960 (Farmers in lower breede river valley pers. comm.). This species is a long lived shrub with 3 generations being longer than the time since ploughing. Livestock grazing is an ongoing threat which is severe as species highly palatable. |
