?Lithocarpus argyrocarpa
Notes
KEP 21712 (type, K!) with young cupules and fruits, was collected in the border area between Kedah (Malay Peninsula) and Siam. Except for the smaller size, the cupules, fruits and leaves, it very closely resembles specimens of L. sootepensis (CRAIB) A. CAMUS from Doi Angka in Siam. More material of both species is, however, needed to draw a definite conclusion.
