Yes - but recently rediscovered - sorry, should have been more specific

Was looking for Leucadendron grandiflorum (to find out whether anything further had happened about the controlled burn) and stumbled into this list

"H. outeniquense is a very rare and localized habitat specialist, and was thought to be extinct after not being recorded in the wild for 70 years. A small subpopulation of fewer than 30 mature individuals was recently rediscovered near the type locality. It is not suspected to be declining, but ongoing monitoring and field surveys are needed."

Just to keep the list up-to-date, Pleiospilos simulans is not Extinct in the Wild (EW) - only known from cultivation -, but Critically Endangered D (http://redlist.sanbi.org/species.php?species=97-37).
