Garg ji, fruit size is also important. In this case, fruits are only 3-4 cm long (not more than 6cm as in case of O. fortunii). I have seen other plants as well but not the fruits in that case. Actually, both species were introduced in India by the Forest Research Institute Dehradun. I may be having flowering twigs of other species as well and will report back to you. Regards
