Oxalis articulata
Oxalis bowiei
Oxalis articulata in the United States commonly has been identified as O. rubra. Oxalis rubra was treated at subspecific rank by A. Lourteig (1982), but subsp. articulata and subsp. rubra have essentially the same native range and occur in similar habitats. Lourteig identified both subspecies in the United States, noting in her key that vestiture is reduced and the sepals are broader in subsp. rubra. Evidence is weak for recognizing more than a single entity. In the Flora of Panama (Lourteig 1980), she recognized only O. articulata, noting that it is naturalized in other parts of America and in the Old World.

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.
