yes
Oxalis
Oxalis is a large genus of flowering plants in the wood-sorrel family Oxalidaceae comprising about 800 of the 900 known species in the family.
 The genus occurs throughout most of the world, except for the polar areas; species diversity is particularly rich in tropical Brazil, Mexico and South Africa.
Ledebouria
Ledebouria is a genus of African bulbous perennial herbs in the Asparagus family, Asparagaceae, subfamily Scilloideae.
 Most members were previously part of the genus "Scilla".
 A number of species are grown by cacti and succulent enthusiasts for their patterned leaves.
Oxalis obliquifolia
Oxalis obliquifolia is an "Oxalis" species found from Ethiopia to South Africa. Oxalis versicolor
Oxalis versicolor or candy cane sorrel is an "Oxalis" species found in South Africa. Oxalis glabra
Oxalis glabra is a member of the wood-sorrel family, Oxalidaceae.
 It is only one of the 800 total species belonging to this family.
 The plant is commonly known as "finger-leaf" due to its trifoliate leaf structure.
 This trifoliate structure can be seen in variations throughout all members of the "Oxalis" genus.
 However, the particularly narrow leaflets of the glabra plant look more like fingers rather than a common clover.
 The plant is native to South Africa and can be found carpeting the ground of woodlands and bushlands. Oxalis barrelieri
