形态特征（Description）：根状茎粗2-3毫米，被覆瓦状鳞片状鞘，每相距3-9厘米生1个假鳞茎。根成束从假鳞茎基部长出。假鳞茎直立或稍弧曲上举，圆柱形，长2-6厘米，粗3-8毫米，顶生1枚叶，基部被鞘腐烂后残留的纤维，干后古铜色，具光泽。叶革质，长圆形，长3.5-13厘米，宽1.2-2.2厘米，先端钝并且稍凹入，基部骤然收窄为长3-7毫米的柄。花葶出自假鳞茎基部，1-3个，圆柱形，直立，连同花梗和子房长4-7厘米，顶生1朵花；花序柄长6-8毫米，粗约1毫米，基部具2-4枚紧抱于花序柄的干膜质鞘；花梗和子房长1-1.4厘米；花苞片膜质，卵形，长约3毫米；花多少点垂，淡黄色带紫色；中萼片近长圆形，长约1厘米，中部宽5毫米，先端急尖或锐尖，具5条脉，无毛，边缘全缘；侧萼片斜卵状三角形，与中萼片近等长，中部宽6毫米，中部以上偏侧而扭曲呈喙状，先端稍钝，基部贴生于蕊柱足而形成宽钝的萼囊，具5条脉；花瓣三角形，长约6毫米，中部宽3毫米，先端急尖，具3条脉，边缘全缘；唇瓣近卵形，中部以下对折，基部具凹槽，与蕊柱足末端连接而形成活动关节，中部两侧扩展，边缘稍波状，先端稍增厚，上面具1-2条肉质褶片；蕊柱粗短，蕊柱齿不明显；蕊柱足长10毫米，其分离部分长约5毫米。花期通常2-5月。
分布（Distribution）：产福建、广东、海南、香港、广西、云南。生于海拔达1300米的山地林中树干上。越南也有。

Roots below pseudobulbs only. Rhizome 0.8-3 mm in diam., sections between pseudobulbs 3.5-8 cm, bract fibers moderately persistent. Pseudobulbs distant, narrowly ellipsoid or obovoid to cylindric, somewhat flattened or not, 1.8-5 × 0.5-0.9 cm. Petiole 0.3-0.9 cm; leaf blade elliptic, 3-9 × 0.8-2.1 cm, rounded to obtuse. Inflorescence erect to spreading, 3-11 cm, 1-flowered, rarely a subumbellate raceme, 2-flowered; peduncle 1.7-8 cm; bracts 3 or 4, longest 3-10 mm; rachis to 0.5 cm; floral bracts ovate, 2.5-5 × 1.5-4 mm, acute. Flowers resupinate, moderately to widely, and simultaneously opening. Pedicel and ovary 8-18 mm. Dorsal sepal recurved, (ovate or) triangular, 9-14 × 6-9 mm, thin, glabrous, base narrowly attached, margin entire, apex acute to acuminate; lateral sepals free, oblique, elliptic to ovate including a winglike, sometimes antrorse widening along lower margin, or triangular, 10-14 × 7-11 mm, base rather broadly attached, otherwise as dorsal sepal. Petals recurved, triangular with lower margin decurrent along column foot, 5-8 × 2.2-4 mm, thin, glabrous, base broadly attached, margins entire, apex acute to acuminate; lip ± reflexed slightly over 1/2 its length, ± elliptic in general outline, 5.5-8 × 5-6 mm (all without artificial spreading), very thick; abaxially with a weak retuse median ridge toward base, surface glabrous; adaxially concave and with a median slit with slightly thickened margins toward base, convex but deeply furrowed toward tip, surface slightly rugose toward tip, apex rounded to apiculate. Column 1.8-3.2 mm, stigma inside without keels, at its base without teeth, column foot without tooth just above ligament; stelidia deltoid to triangular, 0.3-0.8 mm, acute with a minute tooth along upper margin, close to tip, or minutely bifurcate; anther abaxially ± glabrous and with a low, rounded crest; front margin not drawn out, slightly erose.
Epiphytic or lithophytic in forests, thickets, and on various bedrock types including limestone; 600-1500 m. Fujian, S Guangdong, W Guangxi, Hainan, Yunnan [Nepal, Vietnam].
