Moraea quartzicola Goldblatt & J.C.Manning
Status and Criteria
|L. von Staden|
|A rare and localized habitat specialist, known from two locations and potentially threatened by habitat loss.|
|South African endemic|
|Flats below Vanrhyns Pass and the Matsikamma Mountains east of Vanrhynsdorp.|
Habitat and Ecology
|Knersvlakte Shale Vygieveld, Vanrhynsdorp Gannabosveld, Doringrivier Quartzite Karoo|
|Flats and gentle slopes with clay-loam soils covered in quartz pebbles.|
|There are currently no severe threats to the population. It is however potentially threatened by habitat loss to agricultural expansion and mining, which is likely to significantly increase this species' risk of extinction, should it impact the highly localized population.|
Moraea quartzicola is a rare and poorly known species. It was only recently separated from the widespread and common Moraea saxicola (Goldblatt and Manning 2014), and therefore it may be overlooked and possibly more common than records suggest. Currently, it is known from several collections from quartz hills near the foot of Vanrhyns Pass. An old collection with an imprecise locality description suggests it may occur further south along the foot of the Bokkeveld Escarpment and Matsikamma Mountains as far as Klawer.
