Terrestrial, perennial, rhizomatous herbs, to 30–50 cm tall. Rhizome creeping, 5–6 mm in diameter. Elements erect, c. 2–5 cm apart, 1-foliate; petiole 10–27 cm long, slender, canaliculate, green to greenish yellow; leafless sheath 2–5 ×1.0– 1.5 cm, lanceolate, membranous, light brownish, fibrous, soon decayed before first two or three flowers opened, papery when dried; lamina 14–20 × 8.5–12.0 cm, coriaceous, elliptic, margin entire and partly undulate, base cordate, apex sharply pointed or acute, adaxial surface dark green, often greenish yellow when young, abaxial surface pale green, dull. Inflorescence emerging from near leaf base inside leaf sheaths, up to 3 cm long, slender, bearing up to 12 flower buds, opening in succession, two flowers at a time; peduncle glabrous; bract 5–7 spirally arranged the cincinni, 1–2 × 3–5 mm, lanceolate, fibrous, light brown; flower white; labellum 15–17 × 10–12 mm, white with pale pink lilac veins and greenish yellow median band, deeply bilobed, indented c. 10–15 mm, dorsal corolla lobe elliptic, boat-shaped, transparent white with greenish yellow on the upper part, lateral corolla lobes transparent white with greenish yellow on the upper part; staminodes white, 8–10 mm long, apex bilobed, anther thecae 8–10 mm long, elongate, spurs not noted; crest 4 × 2 mm, apex rounded, white with fine hairs; ovary 3–5 mm long, 3–4 mm diameter, ellipsoid or rounded, light green.

Distribution & ecology: — The species is found at Gunung Sepali of Lanjak Entimau Wildlife Sanctuary, occurring on alluvial soil, as well as a lithophyte on rocks in mixed dipterocarp hill forest ( Meekiong et al. 2011).

Conservation status:—Near Threatened (NT).The species is commonly found and well protected within a wildlife sanctuary, a Totally Protected Area. However, the surrounding areas outside the wildlife sanctuary are subjected to logging activities. Therefore, the listing is justified under the NT category ( IUCN 2012).

Discussion:—The flowers of S. salahuddiniana fit well into this group by their relatively smaller dimensions, white labellum with veins, and colliculate pericarp.
