Lithocarpus

Lithocarpus is a genus in the beech family Fagaceae, differing from Quercus in the erect male spikes. The Kew Checklist (see link below) accepts 334 species, though some other texts suggest as low as 100 species. All but one are native to east and southeast Asia; the single exception, Lithocarpus densiflorus (Tanoak), being native to western North America in southwest Oregon and California. The Asian species do not have a well-known English vernacular name, though the generic term stone oak has been proposed.
