zuzu I am sure of the name. I brought the subject up because I suddenly realised that this part of the world has a lot of cultivars of this plant(not just Daylilies). "Show berri" as the name suggests was developed for show. Big, good looking leaves and fruit/drupe is about two inches long and one and half inch in diameter, elongated. Then there is "Sindhi berri", drupe is round, big less then two inches in diameter. I will now be on the look out for this one to send to data base. India has at least eight that I know. About Africa and Bangladesh I have no idea.

PS. Put out an appeal for pictures of Ziziphus cultivars and get them involved. That's for those who ask me where are the others.
