Dear Ron You are surely a great expert of Convolvulaceae, and we would surely like to be guided by you. It is really fortunate that you have found time to interact during Convolulaceae week. It would help us all if you could kindly list the diagnostic differences between I. hederifolia and I. coccinea (and your opinion on whether you agree with The Plant List as synonym of I. rubriflora).
