for cross-pollination I assume that the chinese chestnuts and the dunstan hybrids are compatible. Do you know if chinquapins species can cross-pollinate with other chinquapins and also with chinese and american chestnuts. I was thinking no for american chestnuts since their ranges historically overlapped. The ozark chinquapin can get big IIRC.
