Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Large-flower Primrose-willow Ruderal Marsh
Colloquial Name: Ruderal Large-flower Primrose-willow Marsh
Hierarchy Level: Association
Type Concept: This vegetation is found in flats in the upper reaches of artificial impoundments. Stands are entirely dominated by monospecific patches of Ludwigia grandiflora.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: In the sense of Weakley (2005), the nominal taxon includes both Ludwigia grandiflora ssp. grandiflora (hexaploid, shorter sepals, smaller linear to lanceolate leaves, always densely villous) and Ludwigia grandiflora ssp. hexapetala (decaploid, longer sepals, larger elliptic to oblanceolate leaves, rarely glabrous to sparsely or densely villous). The nominal species Ludwigia grandiflora (sensu lato) has also been known as Ludwigia uruguayensis. This concept accommodates populations of both Ludwigia grandiflora ssp. grandiflora and Ludwigia grandiflora ssp. hexapetala. See Weakley (2005) for more information. The current nomenclatural standard (USDA Plants 2017) recognizes the two subspecies.
