Plumbago zeylanica
 Plumbago zeylanica commonly known as Ceylon Leadwort or Doctorbush is a species of plumbago with a pantropical distribution. Carl Linnaeus described the paleotropical P. zeylanica and neotropical P. scandens as separate species but they are currently considered synonymous. Ceylon Leadwort is a herbaceous plant with glabrous stems that are climbing prostrate or erect.
