Ludwigia grandiflora

Family:ONAGRACEAE
Species:Ludwigia grandiflora (Michx.)Greuter & Burdet
Common Name:LARGEFLOWER PRIMROSEWILLOW
Plant Notes:This species has sometimes been divided into two entities, L. grandiflora s.str. (hexaploid) and L. hexapetala (decaploid). The lack of clear morphological distinction obscures their separation (see Nesom & Kartesz 2000) and octoploid hybrids between the two have been reported (Zardini et al. 1991). When two entities are recognized, the application of the name L. grandiflora to plants having mostly lanceolate leaf blades appears to conflict with the type specimens of L. grandiflora that have spatulate and oblanceolate leaf blades. Spatulate and oblanceolate leaf blades were alleged to be representative of L. hexapetala (Zardini et al. 1991; Nesom & Kartesz 2000).
