科属（Family & Genus）：兰科（Orchidaceae）石仙桃属
形态特征（Description）：根状茎匍匐，较粗壮，直径5-7毫米，具多节，密被鳞片状鞘，生多数根；假鳞茎密接，近长圆形，略带4钝棱，有时上端略收狭，长（2.5-）4-8厘米，宽1-1.5厘米，顶端生1叶。叶长圆状倒披针形、长圆形至近宽倒披针形，长7-25（-35)厘米，宽2-8. 5厘米，薄革质，先端短渐尖或急尖，基部楔形；叶柄长1.5-5厘米。花葶生于幼嫩假鳞茎顶端，开花时叶已基本长成，通常长25-50厘米；总状花序下垂，长5-30厘米，密生数十朵花；花苞片宽卵形，长4-7毫米，宽4-8毫米，具极多密集的脉，多少凹陷，常对折，宿存；花梗和子房长4-5毫米；花白色或略带红色；中萼片近圆形或宽椭圆形，长3-4.5毫米，凹陷成舟状，具5脉，背面中脉略突起；侧萼片完全离生，卵形，长4-6毫米，宽3.5-4毫米，舟状，背面有极明显的龙骨状突起；花瓣近线状披针形，长3-4.5毫米，宽1-1.5毫米，具1脉；唇瓣长4-6毫米，凹陷成囊状，略3裂；侧裂片近宽长圆形，长2.5-3毫米，宽约2毫米，直立，围抱蕊柱；中裂片近长圆形，宽3-4毫米，先端有凹缺，边缘略波状；凹陷部分近基部有2-3条纵褶片或粗厚的脉；蕊柱粗短，长3-4毫米，两侧从下部至顶端具翅，使正面观近圆形；蕊喙宽阔。蒴果倒卵状椭圆形，长1-1.3厘米，宽6-7毫米；果梗长2-4毫米。花期7-9月，果期10月至次年1月。

Coelogyne imbricata (Hooker) H. G. Reichenbach; Cymbidium imbricatum (Hooker) Roxburgh; Pholidota bracteata (D. Don) Seidenfaden; P. henryi Kraenzlin; P. imbricata var. henryi (Kraenzlin) Tang & F. T. Wang; Ptilocnema bracteata D. Don.
Rhizome creeping, rather robust, 5-7 mm in diam., with many nodes, densely covered with scaly sheaths, with many roots. Pseudobulbs contiguous, suboblong, (2.5-)4-8 × 1-1.5 cm, obscurely obtusely 4-ridged, apex 1-leaved. Leaf blade oblong-oblanceolate, oblong, or nearly broadly oblanceolate, 7-25(-35) × 2-8.5 cm, thinly leathery, base cuneate, apex shortly acuminate or acute; petiole 1.5-5 cm. Inflorescence arising from young pseudobulbs with nearly mature leaf at anthesis, usually 25-50 cm; rachis nodding, 5-30 cm, densely many flowered; floral bracts persistent, often conduplicate, broadly ovate, 4-7 × 4-8 mm, with many dense veins, ± concave. Flowers white or slightly tinged with red; pedicel and ovary 4-5 mm. Dorsal sepal orbicular or broadly elliptic, cymbiform, 3-4.5 × 3-4.5 mm, 5-veined, midvein slightly raised; lateral sepals free, ovate, cymbiform, 4-6 × 3.5-4 mm, dorsally strongly carinate. Petals sublinear-lanceolate, 3-4.5 × 1-1.5 mm, 1-veined; lip saccate, 4-6 mm, slightly 3-lobed; lateral lobes embracing column, erect, nearly broadly oblong, 2.5-3 × ca. 2 mm; mid-lobe suboblong, 3-4 mm wide, margin slightly undulate, apex emarginate; disk with 2 or 3 longitudinal lamellae or thickened veins near base. Column nearly orbicular in ventral view, 3-4 mm, thick, both sides with wings; rostellum broad. Capsule obovoid-ellipsoid, 1-1.3 cm × 6-7 mm; fruiting pedicel 2-4 mm. Fl. Jul-Sep, fr. Oct-Jan. 2n = 40.
Epiphytic on trees or lithophytic on rocks in forests; 800-2700 m. SW Sichuan, SE Xizang, S and W Yunnan [Bhutan, Cambodia, India, Indonesia, Laos, Malaysia, Myanmar, Nepal, New Guinea, Pakistan, Sri Lanka, Thailand, Vietnam; Australia, SW Pacific islands].
