Two species, endemic to the Western Cape. Have a mutualistic association with mirid bugs in the genus Pameridea whereby the bugs feed on insects caught on the mucilage-tipped trichomes of the plant and the plant absorbs nutrients from the faeces produced by the bug. Hairs on the tarsi of the bugs enable them to move on the plant without being caught by the sticky mucilage.
