Quercus rekonis is a species of oak in the subgenus Quercus indigenous to Mexico. It was described in 1924 by William Trelease. It is most commonly found in the Mexican state of Oaxaca,[1] but can be found throughout much of western Mexico. Quercus rekonis grows in a subtropical biome.[2]
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.[1]
Quercus rekonis produces ovoid, mucronate acorns. The acorns are typically silky. Quercus rekonis produces 3-4 acorns together at the end of a 6-7 cm long peduncle. The cups of the acorns are scaly, half-round and tomentose. The cups are 1 centimetre in diameter. The acorns mature first year.[1]
