Oxalis filifoliolata

Growing in shale gravel soils on the lower slopes of the Kokerboom forest at Gannabos. Currently known only from this site. Thanks to Jan Suda for pointing me to this ID as I had assumed that it was O.gracilis, which can I guess be forgiven as Jan only described this species in 2013....see
