Scientific Name | Adenandra villosa (P.J.Bergius) Licht. ex Roem. & Schult. subsp. apiculata Strid |
Higher Classification | Dicotyledons |
Family | RUTACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(iii)+2ab(iii) |
Assessment Date | 2019/03/25 |
Assessor(s) | L. von Staden |
Justification | A rare, range-restricted taxon (EOO 1758 km²), known from seven locations and declining due to competition from alien invasive plants. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Riviersonderend Mountains and the Langeberg Mountains. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | North Langeberg Sandstone Fynbos, South Sonderend Sandstone Fynbos, North Sonderend Sandstone Fynbos |
Description | Dry sandstone sand between rocks, 450-1500 m. |
Threats |
| On the southern slopes of the Riviersonderend Mountains alien invasive pines have spread and significantly increased in density over the past 15 years, putting many native local endemic species at risk. At present, scattered pines are present on the north-facing slopes.
Recent observation records from the Langeberg do not record any threats. |
Population |
This rare taxon is known from seven locations, but its distribution range is poorly explored and it may be more common than records suggest. It most often occurs in small, scattered subpopulations, but is sometimes locally common. A continuing population decline is inferred from increasing impact of alien invasive plants in its habitat on the Riviersonderend Mountains.
