Wingleaf Primrose-willow – Ludwigia decurrens

Trying to identify a primrose-Willow growing in sand dunes at Sandy Hook National Park in central NJ. Definitely part of the p-w group of plants – erect/ woody with lance like leaves – characteristic flowers – underside of leaves smooth and a little silvery – sessile – leaves seem to slightly form ridges down main plant stalk. L. decurrens seems a close match but does not seem to be listed as a NJ plant. Thoughts?
Without taking a look at the keys/descriptions for Ludwigia, I wouldn’t discount the possibility of an occurrence of L. decurrens in NJ, since it is listed as present in PA and MD.
