Huernia quinta var. blyderiverensis
Photographed by: Claudio Cravero
I see names thrown around with this sp. often, however it seems that the name stated above is what has become the staple for the accepted name currently.
This Huernia is somewhat of a true specialist too. It really does have a specific preference to which it thrives. Similar to H. quinta you can expect the habitat to require minimal gripping grade, or rather a very thin layer of finer medium for the plants to have their roots truly develop into before reaching some kind of solid rock. The rock makeup is usually made up of dolomite lime; so, it can almost be assumed that calcium and magnesium may play a large factor to both of the Huernia’s habitats. For This plant in particular:
“Huernia quinta var. blyderiverensis or (Huernia blyderiverensis(biosyn.)) is endemic to the Republic of South Africa (Limpopo - Olifants River, Ohrigstad River; Mpumalanga - Blyde River Canyon). Habitat and ecology: Hills along the southern banks of the Olifants River to the slopes of the mountains overlooking the Blyde River Canyon. This range-restricted (Extent of occurence193 km²), habitat specialist is endemic to Poung Dolomite Mountain Bushveld. It is locally very abundant and occurs in rocky sites, where it grows in shallow soils on ledges and rock outcrops. It is not threatened.” - http://www.llifle.com/Encyclopedia/SUCCULENTS/Family/Asclepiadaceae/30727/Huernia_blyderiverensis

Side note: Sympatric speciation not noted, instead sympatric variation can be noted although over time speciation could potentially be noted.
