Discussion
Subspecies brachycarpa grows along the Gulf Coast from southwestern Louisiana to Nueces County, Texas, and more sporadically northward in eastern Texas to south-central Oklahoma.
Subspecies brachycarpa was published initially by Peng as a new combination based on Ludwigia cylindrica var. brachycarpa Torrey & A. Gray, not realizing that the variety was based on Jussiaea brachycarpa Lamarck, which Peng considered to be a synonym of L. glandulosa subsp. glandulosa. Therefore, subsp. brachycarpa is a new subspecies but was invalid when published by Peng since it was not accompanied by a Latin description in 1986; that situation has since been remedied.
