Rhododendron Arboreumthe Plant Is Known As Maha Ratmal, Maha Rath Mal, Asela Mal In Sinhala. The Sinhalese Name Rathmal Is Mostly Used For The Ixoras, Which Are Not In This Family. However, The Rhododendrons Are Not A Common Plant In Sri Lanka, And The Unsystematic Local Name Seems To Bemaha-Rathmal, I.e., Big-Ixora, Applied To Smaller Varieties Which Are More Like Ornamental Azelias. Maha Rath Mala Is Commonly Available In Horton Plain, Knuckles Mountain Range And Many Of The Parts Towards The Center Of Sri Lanka.
