DistributionCollected only from the southern outer Coastal Plain of Brunswick and New Hanover counties, including Long Beach.

Native of South America; in N.A. on the Coastal Plain from VA to FL and MS.
AbundanceVery rare to rare.
HabitatFresh tidal marshes by the Cape Fear River, pineland ditch (NE of Bolivia, Brunswick Co.).
PhenologyFlowering and fruiting June-September.
IdentificationSouth American Seedbox grows 3-6 feet tall, the stems branched, and the narrow leaves alternate and pubescent. The flowers are solitary in axils, petals 1.5-3 cm long, yellow. It is much like L. octovalvis, but the petals are longer (1.5-3 cm vs. 1-2 cm in the native species) and the floral tube is the same length as the calyx segments (vs. markedly longer in the native L. octovalvis). Both of these species are essentially restricted in NC to the lower Cape Fear River area of New Hanover and Brunswick counties. Remember that the exotic species has huge flowers to about 2-3 inches across and a rather short floral tube, whereas the native one has medium-sized flowers about 1 1/2 inches across and a very long floral tube.
Taxonomic CommentsA synonym is Jussiaea neglecta.
