I will take some pics today, but it's likely to be Thom Pi Kan (aka Tong Pykun). Probably not PPK because there are at least two of those properly labeled as "Lemon Meringue" bearing in the grove. The tags were short and they abbreviated some of them. There are several Thai varieties like Okrung, Pim Sen Mun, Nam Doc Mai, Falan, Coc, etc. present. Thanks.
