Family | RESTIONACEAE |
National Status |
Status and Criteria | Vulnerable D2 |
Assessment Date | 2007/04/11 |
Assessor(s) | H.P. Linder, D. Raimondo & P.A. Manyama |

Range | Kogelberg. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Kogelberg Sandstone Fynbos |
Description | Coarse sands that are seasonally damp, 300-600 m. |
Threats |
