Camus n° 405; -- Resembles Q. pinnativenulosa, but this one is long acuminate with a bristle-tipped apex often curly, acorns maturing in 2 years, hairless leaves without any shade of glaucous, a cuneate base, a longer petiole; see HERE to compare with other whole-leaved oaks -- Q. mulleri, true species for the Plant List 2013, could be a variant to 20 m tall, with leaves light green somewhat glaucous, narrowly lanceolate, often falcate, long acuminate, with 25-30 veins pairs at an angle of 60° with midrib; acorn 1.7 cm long, with a short peduncle, and a turbinate, 1 cm long for 0.7 cm high cupule; the cup-scales are oval and smooth; in Mexico it is endemic in the Sierra del Sur (Oaxaca); IUCN Red List category CR) but is not currently protected; -- For Susana Valencia 2004, Q. duratifolia is a true species, but not for J.L. Linares 2006 (El Salvador), neither for POWO. -- For Bartholomew & Almeda 2023, the synonymy for Q. salicifolia is only Q. acapulcensis and Q. tahuasalana.
