| Scientific Name | Ixia brunneobractea G.J.Lewis | Higher Classification | Monocotyledons | Family | IRIDACEAE |
National Status | Status and Criteria | Vulnerable B1ab(i,ii,iii,iv,v)+2ab(i,ii,iii,iv,v) | Assessment Date | 2012/11/02 | Assessor(s) | N.A. Helme, D. Raimondo & L. von Staden | Justification | EOO 107 km², between five and 10 remaining locations continue to decline due to ongoing habitat loss to rooibos tea cultivation. |
Distribution | Endemism | South African endemic | Provincial distribution | Northern Cape | Range | Bokkeveld Escarpment. |
Habitat and Ecology | Major system | Terrestrial | Major habitats | Bokkeveld Sandstone Fynbos | Description | Seasonally wet or marshy places in deep sandy soils. |
Threats | | This species is specific to deep sandy soils, which are highly threatened by rooibos tea cultivation, with many subpopulations recently lost to expanding crop fields. The rapid agricultural development has all but eliminated this species from much of its highly restricted range (Goldblatt and Manning 2011). |
