Description:
Nephelaphyllum pulchrum is a terrestrial orchid species, with fleshy, creeping rhizomes. Pseudobulbs are slender and curved at the tip, dull purple, and about 2–3 cm long. The leaf blades are triangular-ovate, basally cordate, with a tip that is acuminate and blunt, 4–10 cm by 2.5–6 cm, light brown or yellowish green with dark blotches on the upper surface and flushed purple on the underside. They are held erect by a very short leaf stalk. The inflorescence develops at the tip of new pseudobulbs, is about 8 cm long with a 1-cm long sheath, and bears flowers close together. Flowers vary from being almost completely white to very pink, are non-resupinate, with linear and acute sepals and petals that are 1.3–2 cm long and 0.3–1.8 cm broad, downward deflexing, and pale green with purple veins. The lip is upright, entire, ovate, pale yellow, and fleshy, 1.6–2 cm by 1.1–2 cm, shortly spurred, with five longitudinal rows of fine yellow hairs in the middle, tapering into three ridges near the tip. The column is short and broad and about 5 mm long
