Systematics

The Dutch botanist Pieter Willem Korthals described the species in 1844 and classified it as Quercus blumeana in the genus of oaks ( Quercus ).

In the following decades there were several proposals to assign the species to another genus: The Danish botanist Anders Sandøe Ørsted assigned it to the genus Cyclobalanus as Cyclobalanus blumeana in 1866 ; the English botanist James Sykes Gamble chose the taxon Pasania blumeana in 1915 . In 1916, the Japanese botanist Gen'ichi Koidzumi assigned the species to Synaedrys blumeana differently.

The German-American botanist Alfred Rehder put the species in 1919 as Castanopsis blumeana in the genus of the pseudo-chestnut ( Castanopsis ); In 1929 he corrected his earlier view and classified the species under the current taxon Lithocarpus blumeanus in the genus Lithocarpus .
