Dinesh ji,
I couldn't find any specific Tamil name for Artabotrys zeylanicus may be due to rare occurrence of the species in the State.
I however noticed that sometimes the Tamil name of A. hexapetalus, 'Manoranjitham' (மனோரஞ்சிதம்), is also applied to A. zeylanicus (either by error or) possibly because of its similarity with the former species.
