(Fig. 2, 3).
Typus: ECUADOR. Zamora-Chinchipe: road Loja-Zamora, c. 35 km from Loja, Estación Científica San Francisco, 3°58’S 79°04’W, 1800 m, 16.III.2000, Homeier 333 (holo-: BIEL!; iso-: QCNE, MO, LOJA).
Folia rigida. Inflorescentia hermaphrodita solum visa racemiforma, 1-11-flora, rhachidi 0,3-0,7 cm longa.
Trees. Terminal internodes terete, longitudinally furrowed, 2-3 mm in diameter, glabrous. Leaves petiolate; stipules caducous, (narrowly) triangular-ovate, 0.3-0.9 Χ 0.08-0.15 cm, apex acute, glabrous or adaxially puberulent, the adjacent stipules joint at base or to 0.3 mm distant; petiole canaliculate, 0.3- 0.65 cm long, 1.5-3 mm in diameter; lamina coriaceous, rigid, elliptical, 7-16 Χ 3.2-6.9 cm, base shortly attenuate to broadly cuneate, apex shortly (sub-)acuminate, the very apex rounded or obtuse, adaxially glabrous, abaxially sparsely hairy along midvein, the hairs red-brown, 0.3-1.1 mm long; margin not or minutely revolute, entire or very inconspicuously serrulate; secondary veins 8-16 per side, adaxially impressed to prominulous, abaxially prominent, 0.7-1.7 cm distant at middle of lamina, interspersed by 0-1(-4) intersecondary veins. Hermaphroditic inflorescence botryoid, 1-11-flowered, male inflorescence not seen; rachis 1(-3) per axile, subterete to inconspicuously quadrangular, longitudinally furrowed, 0.3-0.7 cm long, c. 1 mm in diameter, ± glabrous or sparsely puberulent with brownish hairs to 0.3 mm long; bracts subopposite, ovate, 0.6-1.3 Χ 0.6-1 mm, apex acute, puberulent, bracteoles not seen; pedicel below articulation to 2 mm long, above articulation subterete, apically inconspicuously widened, 5-10 mm long (in male flowers to 12 mm long), 0.7-0.8 mm in diameter, glabrous. Flowers subglobose in bud; sepals 4, coriaceous, elliptical to suborbicular, strongly concave, 2-3 Χ 1.3-4 mm, rounded, abaxially glabrous, margin ciliate; petals 5, obovate, reflexed, 4-5 Χ 2-4 mm, rounded, margin ciliolate; stamens in hermaphroditic flowers c. 17, in male flowers c. 65 (see remarks), filaments c. 5 mm long, anthers c. 0.4-0.7 Χ 0.3-0.6 mm, in male flowers larger; ovary 2-locular, styles 2, 2.5-3 mm long, stigma inconspicuously broadened. Fruit ellipsoid, longitudinally striate, 2-3 Χ 1.2- 1.5 cm, apically obtuse to subacute, glabrous; seeds not seen.
Distribution. – Only known from Ecuador. Occurs in tropical montane rain forest at about 1800 m.
Phenology. – Flowers in March.
Etymology. – The species epithet refers to the type locality near Zamora.
Additional material examined. – ECUADOR. Zamora-Chinchipe: road Loja-Zamora, c. 35 km from Loja, Estación Científica San Francisco, 1830 m, 7 Apr 2004, Homeier 1375 (BIEL, FR).
Notes. – This species is similar in leaf shape to Q. florida, but contrasts in a rigid-coriaceous leaf texture. The leaf texture is similar to Q. integrifolia Pulle, but this species has longer inflorescences with more flowers. The short inflorescences, in turn, are similar to Q. blackii Pires. However, Q. blackii differs in chartaceous to subcoriaceous leaves and subulate stipules. Male flowers were provided by J. Homeier (no specimen seen).
