Lithophytic herbs, 17.8−23.4 cm tall. Pseudobulbs conical, 6.6−7.8 × 0.8−1.7 cm. Leaves 2−3, oblanceolate, 10.1−16.3 × 1.2−1.4 cm, apex obtuse to acute. Inflorescence a loosely 8−10-flowered, simple to weakly compound raceme; peduncle 49.5−60.0 cm long; rachis 19.4−26.2 cm long. Pedicel 2.2 × 0.2 cm, warty; sepals brownish, dorsal lanceolate, 1.9 × 0.6 cm, laterals lanceolate, 2.0 × 0.6 cm, reflexed, margin entire, apex acute; petals brownish, spatulate, c. 1.7 × 0.7 cm, reflexed, margin entire, apex mucronate; lip with claw 0.15 × 0.25 cm, lateral lobes free in relation to the ovate midlobe, 0.7 × 0.4 cm, white to pink, at a 45° angle to the midlobe (in the flattened lip), not overlapping it, margin entire, apex obtuse, midlobe rounded, 0.7 × 0.9 cm, pink with darker pink streaks, conduplicate, margin undulate, apex mucronate, callus cymbiform, acute; column clavate, 1.0 × 0.3 cm, clinandrium apex tridentate, lateral teeth triangular, apex acute, arms of column elliptic, 0.15 × 0.20 cm, apex obtuse; stigma elliptic, with basal hooks; anther one, yellow, 0.4 × 0.2 cm.
Distribution and habitat:— Endemic to Minas Gerais ( Fig. 10 View FIGURE 10 ).
Phenology:— Flowering September–November.
Etymology:— Named in honour of the collector of the type, Denis Duveen.
Taxonomic notes:— Encyclia duveenii is close to E. alboxanthina and the other species of the “ osmantha alliance” in the phylogenetic tree of Bastos (2014). All these species have a dark yellow anther and broadly spatulate petals and sepals. The reflexed, brownish, longitudinally incurved sepals and petals distinguish E. duveenii from the other members of the alliance.
Selected specimens exmined: BRASIL. Minas Gerais: Botumirim, source of the São Domingos Stream, 1280 m, 29 September 1997, Melo-Silva et al. 1474 ( HUEFS, SP, SPF); Grão Mogol, basin of the Ribeirão da Morte , 900−1000 m, 4 November 1987, Melo-Silva et al. 11478 ( HUEFS, SP, SPF) .
