Oxalis bowiei is a naturalized garden escape in Oroville (Butte County; V. H. Oswald and L. Ahart 1994). Oxalis bowiei Aiton ex G. Don, from the Cape of Good Hope, was described as hoary-pubescent with peduncles about equal in length to the leaves and with red flowers. It perhaps is not the same species as O. bowiei Herbert (1833), provenance unspecified, but the color illustration clearly shows the commonly cultivated plant of contemporary commerce. Apparently neither name has been typified.
