Landscape Plants

This is a new genus, it was established when it was determined that the tanoak or tanbark oak (Lithocarpus densiflorus) is only distantly related to the Asian tropical Lithocarpus, the so-called stone oaks.   Tanbark oak has been moved into Notholithocaprus (i.e., Notholithocarpus densiflorus).  However, it is likely that commercial horticulture will continue to use the traditional name for some time.
Notholithocarpus:  notho, from the Greek, nothos, false; lithocarpus, litho, a stone and karpos, fruit; a reference to the hard acorns.
