Justification | Lachenalia martiniae is known from four to five locations. It has lost habitat to citrus cultivation. It is potentially threatened by future road widening, further crop cultivation and future urban development. It has an extent of occurrence (EOO) of 959 km², and is therefore listed as Vulnerable under criterion D. |
Distribution |
Endemism | South African endemic |
Provincial distribution | Western Cape |
Range | This species is endemic to South Africa, and is found along the Olifants River Valley between Vanrhynsdorp and Clanwilliam. |

Major habitats | Citrusdal Vygieveld, Knersvlakte Shale Vygieveld, Citrusdal Shale Renosterveld, Vanrhynsdorp Shale Renosterveld, Northern Inland Shale Band Vegetation |
Description | It occurs in Karoo Broken Veld on heavy clay soils in rocky habitats and on sandstone outcrops. |
Threats |
Historically, about 20% of this species' habitat has been lost to crop cultivation (mainly fruit orchards). There has been no significant agricultural expansion at any of the known locations within the past 30 years, but habitat loss and degradation remains a potential threat. |
