Since information is scarce about the rarer Cyphomandras, i m sharing my experience, the first year it produced lots of flowers but they all fell without producing fruit. The second year some flowers fell immature, but most of them turned to fruit, without pollination from a second plant. The fruit is the size of an olive, some are the size of a big fat olive, while others are the size of a small olive; anyway, they are generally not palatable, while some of them might be called nearly tasty, mostly their taste is usually that of a lightly baked eggplant with some fruity sweetness added, and just as often eggplants, the c. corymbiflora fruit give a biting/stinging sensation to the palate (solanoiid alcaloids i suppose); the fruit skin is very thin and soft, so they should be eaten with the skin (after they fall from the bush and get soft to finger pressure; before that, they are hard like wood); however, the fruit, which smell like tomato leaves when picked, if kept for a little while they give a fragrance similar to feijoa. In small quantities they can make an interesting addition to a fruit salad. There is no copyright about this information, you can share with anyone.
