The photos in this post were originally published here as belonging to O. undulosa, but Derek Tribble of London kindly made me aware of them representing in fact O. gymnodiscus. For more information see Derek’s comment.
This is a tuberous, erect or sprawling plant to 35 cm tall, with leathery, oblanceolate to elliptic leaves which are tapering below and somewhat clasping.

Its area of distribution is from Cedarberg to Worcester and Little Karoo to as far east as Port Elizabeth on sandy slopes and flats.
