Quercus ngochoaensis (Fagaceae), a new species from Ba Vi National Park, northern, Vietnam
A new species of Quercus (Fagaceae), Q. ngochoaensis, from Ba Vi National Park, Ha Noi, northern Vietnam is described and illustrated. This species is morphologically similar to Q. glauca in having glabrous twigs, cuneate leaf base, two or three fruits per infructescence, almost entire margin of lam...
