Ludwigia capsule

Oh yeah, and here’s what the distinctive seed “boxes” of Ludwigia octovalvis look like. This picture, like the last few, is from August 6th at a sumpy place I know on the Blackland Prairie in northeast Austin. To see the regions in the southeastern United States where this species grows, you can check out the USDA map.
