            <p>Diagnosis.</p>
            <p> Aphyllorchis yachangensis is similar to  A. caudata but differs from the latter mainly by its hypochile with two wings of 1-1.4  × 0.4-0.6 mm (vs. 2-3  × ca. 4 mm), epichile adaxially smooth (vs. densely papillose), lateral lobes triangular-ovate (vs. semicircular), sepals acute at apex (vs. long cuspidate) and column clavate (vs. approximately cylindrical). Detailed morphological comparisons between  A. yachangensis and  A. caudata are provided in Table 1. </p>

Bracts lanceolate, shorter than pedicel and ovary, 1.2-3 cm long, 2.8-6.8 mm wide, yellow-green, usually with many dark purple stripes and spots on abaxial surface, sparsely glandular puberulent. Ovary cylindrical, yellow-green, usually with many dark purple stripes and spots, sparsely glandular puberulent, 2.2-2.8 mm in diameter, including pedicel to 2.3-3.5 cm long. Sepals yellow-green, usually with many dark purple stripes and spots on abaxial surface, abaxially sparsely glandular puberulent; dorsal sepal lanceolate, slightly concave, 2.5-4 cm long, 7.9-10.7 mm wide, apex acute, reflexed; lateral sepals lanceolate, slightly oblique at base, 2.5-4 cm long, 6.1-8.2 mm wide, apex acute, reflexed. Petals lanceolate, reflexed, 2.2-2.7 cm long, 5.6-7.2 mm wide, yellow-green, pale purple to dark purple at base, apex acute. Lip 2-partite; hypochile narrow, concave, 6.6-7.1 mm long, 3.6-4.5 mm wide, yellow or reddish brown, with 2 unobvious wings at base; wings semicircular, 1-1.4 mm wide at base, 0.4-0.6 mm tall; epichile ca. 1.9-2.2 cm long, 1.3-1.5 cm wide when flattened, 3-lobed, yellow with pale purple, or purple to dark purple, adaxially smooth, margin slightly erose; lateral lobes triangular-ovate, 8.2-8.9 mm long, 3.6-4.3 mm wide; mid-lobe narrowly triangular, 1.1-1.3 cm long, 5.6-5.9 mm wide, acute at apex, margin slightly involute. Column clavate, arcuate, 1.4-1.6 cm long, 1.8-3.3 mm in diameter in lower part, 4.3-6.1 mm in diameter in upper part, yellow-green, usually purple from middle to base; stigma ovate, slightly concave; staminodes 2, on both sides of apex, yellow-white to pale yellow-green; pollinia 2, ovate, granular-farinaceous, 4 mm long, yellow; anther cap ovate, slightly laterally compressed, 4 mm long, pale yellow.</p>
