Scientific Name | Euchaetis tricarpellata I.Williams |
Higher Classification | Dicotyledons |
Family | RUTACEAE |
National Status |
Status and Criteria | Vulnerable B1ab(ii,iii,iv,v)+2ab(ii,iii,iv,v) |
Assessment Date | 2010/08/31 |
Assessor(s) | N.A. Helme & L. von Staden |
Justification | EOO between 722 and 912 km², AOO <700 km², less than 10 known locations continue to decline due to expanding cultivation of deep sandy soils for potatoes and rooibos tea. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Piketberg to Olifants River Mountains and Redelinghuys. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Piketberg Sandstone Fynbos, Leipoldtville Sand Fynbos |
Description | Mainly deep sandy soils on flats, occasionally in rocky sandstone fynbos. |
Threats |
| Subpopulations occurring in deep sandy soils on lowlands are declining due to recent extensive expansion in potato and rooibos tea cultivation. Two locations in rocky soils at higher altitude are unlikely to be impacted by agriculture, but is potentially threatened by alien invasive plants and too frequent fire. |
Population |
Extremely rare in some areas with subpopulations of less than 50 plants, but some larger subpopulations of more than 500 plants have also been observed.

Population trend | Decreasing |
