Oxalis flava var. flava, commonly the yellow palm sorrel or in Afrikaans the bobbejaanuintjie (baboon nutsedge or nut-grass) or dikvingersuring (thick finger sorrel), is a bulbous perennial reaching 15 cm in height.
The sepals usually have orange warts near their tips. The solitary, stalked flowers are white, mauve or yellow, seen late in autumn to early winter. The corolla diameter is 1,5 cm to 1,8 cm.
This variety is widespread, found in the Northern Cape and the Western Cape from Namaqualand to the Cape Peninsula and eastwards to Riversdale. The photo was taken near Nieuwoudtville.
The habitat is variable, from Namaqua Klipkoppe, the Knersvlakte on sandy flats and lower slopes. The plant is not considered to be threatened in its habitat early in the twenty first century (Manning, 2007; Le Roux, et al, 2005; Manning and Goldblatt, 1997; iNaturalist; http://redlist.sanbi.org).
