科属（Family & Genus）：兰科（Orchidaceae）兜兰属
形态特征（Description）：地生或半附生植物，具粗短的根状茎和少数稍肉质而被毛的纤维根。叶基生，二列，4-6枚；叶片狭椭圆形至椭圆状长圆形，长7-18厘米，宽3.5-4.5厘米，先端钝并略有不对称，上面有深浅绿色（或有时略带灰色）相间的网格斑，背面具极密集的紫点或几乎完全紫色，中脉在背面呈龙骨状突起，基部收狭成叶柄状并对折而彼此套叠。花葶直立，长5-12厘米，紫褐色，被白色短柔毛，顶端通常具1-2花，罕有3花；花苞片宽卵形，长1-2.5厘米，宽1-1.5厘米，先端略钝，背面被短柔毛并有龙骨状突起，边缘具缘毛；花梗和子房长3-4.5厘米，被短柔毛；花直径5-6厘米，淡黄色或罕有近象牙白色，具紫色细斑点；中萼片宽卵形，长2.5-3厘米，宽亦相近，先端钝或急尖，两面均被微柔毛，但上面有时近无毛，边缘多少具缘毛，尤以上部为甚；合萼片与中萼片相似，长宽约2厘米，亦有类似的柔毛；花瓣斜的椭圆形、宽椭圆形或菱状椭圆形，长3-4厘米，宽1.8-2.5厘米，先端钝或近斜截形，近无毛或略被微柔毛；唇瓣深囊状，狭椭圆形至圆锥状椭圆形，长2.5-3厘米，宽约1.5厘米，囊口宽阔，整个边缘内弯，但前方内弯边缘宽仅1-2毫米，基部具短爪，囊底具毛；退化雄蕊宽卵形至宽卵状菱形，长1-1.2厘米，宽8-10毫米，先端略有3小齿，基部收狭并具耳。花期通常6-8月。
分布（Distribution）：产广西、贵州和云南。生于海拔300～1400米的石灰岩地区多腐殖质土壤上或岩壁缝隙或积土处。东南亚也有分布。

Yong Zhang; P. concolor var. immaculatum Z. J. Liu & J. Yong Zhang; P. wenshanense Z. J. Liu & J. Yong Zhang f. album O. Gruss & Petchleung.
Plants lithophytic or terrestrial. Leaves 4-6, distichous; blade abaxially purple or densely marked with purple speckles, adaxially tessellated with dark and whitish or light green, oblong or oblong-elliptic, 7-21 × 3.5-5.5(-7.5) cm, leathery, rounded and minutely bilobulate at apex. Scape suberect or arching, terminating in 1 or 2(or 3) flowers; peduncle green, heavily spotted purple, 5-7(-8) cm, densely white pubescent; floral bract green, ovate, conduplicate, 1-3(-4) × 1-2 cm, abaxially with purple speckles and along midvein hairy, ciliate; pedicel and ovary 3-4.5 cm, densely white pubescent. Flowers slightly scented, 5-7 cm in diam., usually yellowish to ivory-white ± finely spotted with purple or brown-purple throughout. Dorsal sepal broadly ovate, 2.5-4.2 × 2.4-4.4 cm, abaxially slightly puberulent on midvein, ciliate, apex obtuse to retuse; synsepal similar to dorsal sepal, slightly smaller. Petals obliquely elliptic to rhombic-elliptic, 3-5 × 1.8-3.1 cm, both surfaces very minutely puberulent, ciliate, rounded at apex; lip ellipsoid to ovoid, 3.5-4.5 cm; pouch 2.2-3 × 1.4-1.7 cm, outside very minutely puberulent, apical margin incurved. Staminode ovate to ovate-triangular, 10-12 × 8-11 mm, basal margin sometimes minutely ciliate. Fl. May-Aug. 2n = 26.
Crevices of shaded cliffs or rocky and well-drained places in limestone areas; 300-1400 m. W Guangxi, S Guizhou, S Yunnan [Cambodia, Laos, Myanmar, Thailand, Vietnam].
Paphiopedilum concolor is a widespread species very variable in leaf markings and floral morphology and coloring. Based on these variations, many varieties were described recently, including P. concolor var. dahuaense and P. concolor var. immaculatum from Guangxi (Acta Bot. Yunnan. 22: 393. 2000). Paphiopedilum wenshanense f. album (Orchidee (Hamburg) 53: 383. 2002) seems to be the same taxon as P. concolor var. dahuaense.
