This may be largely restricted to the southern Great Lakes region (PL), but it has received varied taxonomic treatments and mappings (e.g. compare D for Ind. with Co for Ohio). In Ky. the name has been applied to colls. from FAYE, JESS, MADI and MERC (EKY, KY), but further revision is needed to see if these plants are just forms of umbilicata. V. chenopodifolia has distinct fruits with relatively wide fertile locules (Ware 1982; Cr, W), and like umbilicata it differs from radiata in its relatively eciliate bracts and larger flowers (F).
