To which taxonomic category do both Lithocarpus and Maackia belong?
Lithocarpus Lithocarpus is a genus in the beech family Fagaceae, differing from "Quercus" in the erect spikes of insect-pollinated male flowers and the short styles with punctate stigmas on the female flowers. The World Checklist (see link below) accepts 334 species, though some other texts suggest as few as 100 species. About 100 Asian species of the genus were formerly treated in the genus "Pasania". All are native to east and southeast Asia. These Asian species do not have a well-known English vernacular name, though the generic term stone oak has been proposed.
Lucilina Lucilina is a genus of polyplacophoran molluscs. It includes species known from fossil remains, as well as living species. It is often considered a subgenus of "Tonicia".
