Taxonomic notes

Synonyms: L. alata.[1]

Varieties: none.[1]

The genus Ludwigia was established by Carl Linnaeus in 1753 and the species was recognized by Steven Elliot.[2]


“Repent or erect, usually branched, short-lived perennials, or rarely annual. Floral parts in 4-7’s; hypanthium not prolonged beyond the ovary. Capsules longitudinally or poricidally multiseriate, rarely uniseriate. Most of the erect species produce basal offshoots, which have ovate to obovate leaves, in the late summer and fall. Bracteoles occur in pairs on the pedicel or stipe or on the base of the hypanthium.”[3]

"Similar to L. alata. Seeds cylindric; sepals ca. ½ length of capsules; capsules 4-6 mm long."[3]


Occurs along the Atlantic coast of southern North Carolina, South Carolina, eastern and southern Georgia, and the Florida peninsula, and extends west to the central panhandle of Florida.[2]



Habitats of L. lanceolata include depression marshes, hillside seepages, shallow water of titi-cattail ponds, pine flatwoods, lake edges, between coastal dunes and lakes, and cypress pond pine swamps. It occurs in disturbed areas such as powerline corridors and ditches. Associated species include Bidens laevis, Magnolia, Nyssa, Pickneya, Liquidambar, Quercus, Ludwigia linearis, Juncus trigonocarpus, Fuirena scirpoidea, Xyris fimbriata, Woodwardia, Ludwigia octovalvis, L. decurrens, Rhynchospora chalarocephala, Xyris fimbriata, Bidens mitis, Hypericum cistifolium, Typha, and Juncus repens.[4]


This species flowers from June through October.[5]

This is a self-compatible perennial that reproduces sexually and vegetatively. Produces hybrids with L. pilosa and L. suffruticosa.[2]


Ludwigia lanceolata was observed at the Archbold Biological Station to be visited by wasps such as Parancistrocerus salcularis rufulus (family Vespidae).[6]
