about 12 years ago we bough a tree from a local nursery. This was a unusual because from what I understand is a very lately discovered somewhere in Central Texas. about 1980 or so. Tree name starts with P and spelled something like, "Ponsinut". Spelling could be anything like that. All I can remember is it sounded like that. Unusual in that it had very, very large nuts, 0ver 3 in by 1 in thick. Got my attention. Planted and it is a big tree now. Needs a pollinator so no nuts produced. Starts with little nuts but they don't complete.. Working on that. Planted some around. I cannot find anything about this type Pecan. Once years ago I did run across something about but didn't save and have not been able to find since. Wonder If anyone here might help. Thanks
