This is a widely distributed and very variable tropical weed, 
whose African forms have been described under the names I have 
quoted above. The remainder of the synonymy will be found at 
p. 235 of Thwaites's * Enumeration of Ceylon Plants. The colour 
of the corolla is generally pale yellow or white, with a few light 
purple spots on the lower lip.
