Pholidota uraiensis Hayata.
Rhizome creeping, 2.5-3.5 mm in diam., branching, densely covered with scaly sheaths, nodes sparsely rooting. Pseudobulbs borne 1-3 cm apart on rhizome, narrowly ovoid to ovoid-oblong, 1-2 cm × 5-8 mm, embraced by leathery sheaths when young, apex 2-leaved. Leaf blade linear or linear-lanceolate, 2-8 × 0.5-0.7 cm, papery, margin often ± recurved, apex shortly acuminate or subacute; petiole 2-7 cm. Inflorescence arising with young pseudobulb and young leaves from base of last pseudobulb, 3-5 cm; rachis 10- or more flowered, straight; floral bracts caducous, ovate-oblong. Flowers white or yellowish, ca. 4 mm in diam.; pedicel and ovary 2-3 mm. Dorsal sepal ovate-oblong, ± cymbiform, 3-4 × ca. 2 mm, dorsally slightly carinate, apex obtuse; lateral sepals ovate, oblique, slightly wider than dorsal sepal. Petals broadly ovate-rhombic or broadly ovate, 2.8-3.3 × 2.8-3.2 mm; lip broadly elliptic, cymbiform, ca. 3 × 4-5 mm, subtruncate or obtuse; disk without appendages. Column ca. 2 mm, thick, winged on both apical sides; rostellum small. Capsule obovoid, 6-8 × 4-5 mm; fruiting pedicel 2-3 mm. Fl. Apr, fr. Aug-Sep.
