根状茎较粗壮，缩短，生密集的假鳞茎；假鳞茎狭卵形或长圆形，长2.5-4.5厘米，宽7-12毫米，顶端生1叶。叶狭椭圆形或狭椭圆状披针形，长15-25厘米，宽2-3.5厘米，先端近渐尖，基部收狭；叶柄长3.5-8厘米。花葶生于幼嫩假鳞茎顶端，开花时叶已基本长成，长18-25厘米或更长，常多少下垂；总状花序疏生12-18朵花；花苞片椭圆形，在果期已脱落；花白色略带粉红色，唇瓣带淡褐的白色，柱头红色；萼片宽卵状椭圆形，长5-7毫米，宽4-6毫米；侧萼片背面有龙骨状突起；花瓣卵状椭圆形，长4-5毫米，宽约2.5毫米，先端钝；唇瓣轮廓为宽长圆形，长5-6毫米，宽约3毫米，约在上部3/5处缢缩成前后唇；后唇中央凹陷成浅杯状，边缘平展，宽约1毫米，内有3条粗脉从基部延伸至中部以上；前唇横长圆形，先端有凹缺，边缘略波状；蕊柱长约3毫米，顶端有宽翅围绕药床。蒴果狭倒卵形，长约2厘米，宽5-6毫米；果梗长2-3毫米。花期5月，果期不详。
产广西（罗城、都安、靖西、南丹、环江、凤山）和贵州南部（惠水）。生于疏林下或稍荫蔽的岩石上，海拔500-900米。模式标本采自贵州。
Schlechter在发表此新种时说是产四川，实为贵州之误。其模式标本 J. Esguirol 2088系采自贵州南部的惠水县天生桥。
本种体态甚似蜂腰兰Bulleyia yunnanensis Schltr .，特别是叶的形态更难区别。但本种假鳞茎只生1枚叶，花序轴不为左右曲折，不同于蜂腰兰。E. F. de Vogel (1988) 与G. Seidenf aden (1992) 的图中，唇瓣先端有2个肥厚的附属物，但在模式标本的花中未见此附属物。

单叶石仙桃 dan ye shi xian tao
Pholidota wenshanica S. C. Chen & Z. H. Tsi.
Rhizome short, stout, 8-10 mm in diam., with scaly sheaths. Pseudobulbs borne close together, narrowly ovoid, oblong, or subcylindric, 2.5-8 cm × 6-12 mm, apex 1- or 2-leaved. Leaf blade narrowly elliptic, narrowly elliptic-lanceolate, or oblong-lanceolate, 15-30 × 2-3.5 cm, apex acuminate; petiole 3.5-8 cm.

Flowers white and slightly tinged with pink, or yellowish brown, ca. 5 mm in diam., lip white, tinged with pale brown or with yellow blotches, stigma red; pedicel and ovary 3-4 mm. Sepals broadly ovate-elliptic, 5-7 × 3-6 mm, 7-veined, acute; lateral sepals dorsally carinate. Petals ovate-elliptic, 4-5 × 2.5-3 mm, 3-5-veined, obtuse; lip broadly oblong or subovate in outline, 5-6 × 3-3.5 mm, contracted into epichile and hypochile at apical 3/5; hypochile ca. 1 mm wide, shallowly cupular in center, margin spreading horizontally, with 3 or 4 thickened veins extending from base to above middle; epichile transversely oblong or elliptic, 4-5 mm wide, margin slightly undulate, apex emarginate. Column 2.2-3 mm, apex broadly winged. Capsule narrowly obovoid, ca. 2 cm × 5-6 mm; fruiting pedicel 2-3 mm. Fl. May, Dec.
Sparse forests, shaded rocks; 500-1600 m. N and W Guangxi, S Guizhou, SE Yunnan [Vietnam].
