Plants 10-25 cm tall. Stem erect, with (2 or)3-5 leaves near base. Leaves abaxially pale red, adaxially blackish green with 5 silvery-red veins, oblong-lanceolate to elliptic, 3-7 × 1.7-3 cm, fleshy, apex acute or mucronate; petiole-like base 1.5-2.2 cm. Inflorescence pubescent, with 2 or 3 sterile bracts; rachis 3-8 cm, laxly few to more than 10-flowered; floral bracts reddish, ovate to ovate-lanceolate, ca. 1.5 cm, membranous, margin minutely ciliate, apex acuminate. Flowers white tinged with red, ca. 7 mm in diam.; ovary 1.5-2 cm including pedicel, pubescent. Dorsal sepal ovate-elliptic, cymbiform, 8-9 × 4.5-5 mm; lateral sepals obliquely ovate to subelliptic, 9-10 × 4.5-5 mm, abaxially with a very short keel toward apex. Petals obliquely ovate, 8-9 × 2-2.2 mm, apex obtuse; lip 9-10 mm; hypochile containing 2 large fleshy calli; mesochile ca. 2 mm; epichile 5-6 mm wide. Column ca. 5 mm. Fl. Feb-Apr.
Damp areas along valleys in evergreen broad-leaved forests; 900-1300 m. Guangdong, Guangxi, Hainan, S and SE Yunnan [Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Thailand, Vietnam].
Though the combination Ludisia discolor is frequently attributed to Richard (Dict. Class. Hist. Nat. 7: 437. 1825) in the literature, Blume appears to be the first to have transferred the epithet validly.
