Scientific Name | Ixia leipoldtii G.J.Lewis |
Higher Classification | Monocotyledons |
Family | IRIDACEAE |
National Status |
Status and Criteria | Critically Endangered B1ab(iii,v)+2ab(iii,v); D |
Assessment Date | 2012/10/31 |
Assessor(s) | P. Goldblatt, J.C. Manning & D. Raimondo |
Justification | EOO <10 km², known from one subpopulation of fewer than 50 plants, and threatened by ongoing habitat loss to expanding vineyards. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | Barrydale. |
Habitat and Ecology |
Major system | Terrestrial |
Major habitats | Montagu Shale Renosterveld |
Description | Stony clay-loam soils in renosterveld. |
Threats |
| Remaining plants occur in small fragments among crop fields and are threatened by ongoing habitat loss. |
Population |
Fewer than 50 plants remain in and near rocky outcrops among ploughed fields, and continue to decline. The only known population occurs near Barrydale, however, the type collection is apparently from east of Prince Albert. Several searches in this area for this species have been fruitless, and the occurrence of this species around Prince Albert is now considered doubtful (Goldblatt and Manning 2011).
