Lotononis densa (Thunb.) Harv. subsp. densa
|Lotononis gracilis (E.Mey.) Benth. (in part), Lotononis gracilis (E.Mey.) Benth. var. brevipetiolata Dummer|
Status and Criteria
|D. Raimondo & L. von Staden|
|A range-restricted species (EOO 44-147 km²), remaining at between one and four locations after 90% of its habitat has been lost to agricultural expansion. It continues to decline due to ongoing habitat loss and degradation.|
|South African endemic|
|Swartland between Moorreesburg and Paarl.|
Habitat and Ecology
|Swartland Shale Renosterveld, Boland Granite Fynbos|
|Shale and granite soils in renosterveld, 200 m.|
|Less than 10% of this species' renosterveld habitat remains intact, after most has been converted to crop fields. At three of four localities known through historical collections, small renosterveld fragments remain, but these still need to be surveyed to determine the condition of the habitat. In general, renosterveld fragments within the Swartland continue to be degraded due to overstocking with livestock, as well as a lack of fire. On the Paardeberg it is threatened by competition from alien invasive plants.|
This taxon is known from only a few collections, most predating the 1970s. It was recorded in 2011 on the Paardeberg near Malmesbury, but remaining vegetation at three other historical localities still need to be surveyed to determine if any plants survive. The Paardeberg population may be the only remaining population, in which case this species will qualify for the category Critically Endangered.
