I have landed. I have shown pics of these a few times and they are irregular and never have the skirt/crown at the top that is regular. Newer selections tend to be less irregular in am elephant man kinda way but they have a little grit near the skin. You'd hoch AP and gefner up in horror after trying one of these.
The one in the pic on its own looks like it but the group of them lower dont quite conform. So far as taste goes onlu a few of its descendants can match it in the Annona world, according to local Annona researchers and breeders. When crossed with AP and with cherimoya (eg Fino...) the offspring are diminished. I digress sorry..... In the last pic it almost looks like an AP X mammoth but if its nearly seedless, a little grit near the skin, has hollow empty seeds and a way better taste than AP or gefner it probably is a selection of mammoth.Not many bear fruit of the impressive size reported pre say WW1 these days.
