Lasiosiphon macropetalus (Meisn.) Meisn.
|Gnidia macropetala Meisn.|
Status and Criteria
Data Deficient - Taxonomically Problematic
|L. von Staden|
|The genus Lasiosiphon is in need of revision, and species remain poorly known and difficult to assess. If this species has a limited distribution in southern KwaZulu-Natal, it is likely to be in danger of extinction, but if it is widespread across the Eastern Cape and KwaZulu-Natal, it is unlikely to be threatened. Until taxonomic revision can resolve the distribution range, its risk of extinction cannot be confidently assessed.|
|South African endemic|
|Eastern Cape, KwaZulu-Natal|
|Uncertain, possibly restricted to a small area in southern KwaZulu-Natal between Durban, Pietermaritzburg and Kokstad, but may occur as far south as East London and as far north as Vryheid.|
Habitat and Ecology
|Grassland, Indian Ocean Coastal Belt, Savanna|
|Margins of bush clumps in grassland.|
|Threatened by ongoing habitat loss to urban expansion around Durban, Pinetown, and Pietermaritzburg. Further south towards Kokstad, this species has lost extensive habitat to timber and sugarcane plantations, and only small remnants of its habitat remains. In this area it continues to decline due to expanding rural settlements.|
This species is known from only a few records, but it may be confused with other, similar species and therefore overlooked and more common and widespread than records suggest. Most records are from a small area in southern KwaZulu-Natal, where it is declining due to ongoing habitat loss and degradation.
