Beautiful clear pics. Following on from Lila.... Maybe Crotalaria agatiflora. http://www.smgrowers.com/products/plants/plantdisplay.asp?plant_id=471 http://toptropicals.com/pics/garden/m1/Podarki5/Crotalaria_agatiflora3866MarTol.jpg
Thanks, I ruled out Crotalaria agatiflora because it looked different than the photos I have of this plant but I guess they were just minor variations that don't change the species.
