The leaves of Quercus rekonis measure 16-17 centimetres in length and 4.5-6 centimetres in width. Quercus reckonis is deciduous. The leaves of Quercus rekonis are oboval-lanceolate or oblanceolate, the apex is attenuate. The leaf base is narrowly rounded. The leaves of Quercus rekonis have wavy margins with apical half-toothed with 4 pairs of obtuse teeth. The tops of the leaves are hairless with a dull blue-green colour. The bottoms of the leaves contain sparse whitish tomentum. The leaves have 10-12 vein pairs at a 42° angle with the midrib. The leaves petioles are 8 millimetres long.[2]
