Frankly I have not been able to find any satisfactory specimen of Plumeria alba till now. White flowers are found in both P. alba and P. rubra, and even P. rubra may have acute to obtuse leaves some times in the same tree. The only reliable feature seems to be the prominent marginal connecting vein in P. rubra, and it being poorly developed in P. alba. I would be grateful if any member uploads a true P. alba, focussing on marginal vein to make things clear.
