Hi, congrats!!! Campomanesia is one if my favourites genous. The leaves are similar to c. lineatifolia, chamba, and the fruit obviously is similar to many campomanesias, but it remembers me sete capotes specially, c. guazumifolia. This last one tastes like an orange but with sand apple texture to me, and when it is overripe it tastes like jaboticaba. But, yes, you can say it tastes a bit like pear, very nice.
I dont have schlechtendaliana, is it too tropical? I grow guazumifolia, lineatifolia and xanthocarpa.
