Lithocarpus corneus (Fagaceae), a new record for the Flora of Thailand

Abstract

A new record for the Flora of Thailand is reported, Lithocarpus corneus (Lour.) Rehder, collected during fieldwork in Phu Wua Wildlife Sanctuary, Thailand. For this species we provide illustrations, colour images and a description of the collecting locality. The species is unique for Thailand by its serrate leaves, cup-shaped to discoid cupules, a cupule surface covered with triangular to rhomboid bracts arranged in a diamond pattern and an oblate to depressed subglobose nut. Finally, we discuss important morphological differences with other Lithocarpus species found in Thailand.
