Discussion

Oxalis intermedia is recognized by a combination of its large, obtriangular leaflets; numerous, small flowers; and usually clustered bulbs. It was collected in California in 1934 and Massachusetts in 1940 but does not appear to have become naturalized in either state. Plants in the flora area are usually without fertile fruit.
