Thank you sir for the detailed clarification. But the plant list have listed Z. mauritiana in the list, but as I have mentioned earlier the spelling is different for the genus ( http://www.theplantlist.org/tpl/record/tro-50137113) here it is Zizyphus and then they mention that Zizyphus mauritiana doesn't have any synonym. Further, there is yet another genus with a spelling Ziziphus in which they have included jujuba as Ziziphus jujuba with R. jujuba and R. zizyphus as synonym (http://www.theplantlist.org/tpl/record/kew-2470699).
