        The showy Cypripedium fasciolatum has the largest flowers of all Chinese species, only some forms of Cyp. tibeticum can rival it in flower size. The type collection was made 1892 by the French missionary Paul Guillaume Farges in former Northeast Sichuan, today part of Chongqing province. Field notes by Farges mention a pink coloration of the flower which has subsequently let to confusion of Cyp. fasciolatum with Cyp. tibeticum King ex Rolfe and Cyp. franchetii E.H. Wilson in the literature. Photos taken in June 2006 of Cyp. fasciolatum in Chengkou county, North Chongqing, in the region of the type collection, show plants of typical Cyp. fasciolatum with pinkish white lips. Only a very small population is known so far in Huanglong, growing in open to dense shrub at an altitude of about 2000 m. The plant has the overall yellow coloration typical for populations known from West Sichuan, where Cyp. fasciolatum is relatively common. In Huanglong, the plants reach 35-40 cm in height and have flowers of a diameter between 10-12 cm, elsewhere the diameter can be some centimeters more. Newly opened flowers have a pleasant sweet fragrance not unlike roses, when the flower ages the scent turns into something more pungent and unpleasant.

        Flowering: May. Note:
A close relative of Cyp. fasciolatum is Cypripedium farreri W.W. Smith, 1916, published by William Wright Smith in Notes of the Royal Botanic Garden Edinburgh 9:102. 1916. So far Cyp. farreri has not been found in the Huanglong National Park, but it was discovered in 2005 by rangers of the Wanglang National Panda reserve in the southwestern part of the reserve close to the border with Huanglong. Cyp. farreri is smaller than Cyp. fasciolatum and reaches a height of 20-30 cm. It has often just two leaves per stem. The single flower is around 6 cm across and differs from Cyp. fasciolatum by the usually less twisted and broader petals and the lip which is constricted towards the opening and thus pitcher or urn-shaped. The opening of the lip is strongly dentated while in Cyp. fasciolatum the opening is surrounded by slightly elevated small knobs of dark red coloration. Cyp. farreri occurs at altitudes from 2600 m (Southern Gansu) to 3400 m (Northwest Yunnan).

        在中国杓兰属植物中，大叶杓兰花最大，并且色彩艳丽。只有西藏杓兰的一些类型花的大小可与大叶杓兰相比。大叶杓兰的模式标本是法国传教士保罗·纪尧姆·法格1892年在四川西北部城口县采到的，该地区如今是重庆市的一部分。法格曾提到这个种在野外的一些特征，如花朵粉红色。正是他的野外记述使得后人在文献里常把大叶杓兰、西藏杓兰以及毛杓兰相互混淆。根据我们2006年6月在模式标本产地重庆北部城口县所拍摄的大叶杓兰照片上可以发现一些法格描述的踪迹，照片显示大叶杓兰唇瓣颜色是带浅粉红色的白色。到目前为止，大叶杓兰在黄龙仅发现有一个居群，并且该居群植株个体数很少，生长在开旷茂密的灌木丛中，海拔约为2000m。在四川黄龙，大叶杓兰植株高一般为35-40厘米，花朵直径通常为10-12厘米，花颜色与广泛分布于四川西部其他地方一样为黄色。但其他地方的大叶杓兰花更大，可以比黄龙的花大出好几厘米。刚刚开放的大叶杓兰，其花朵常散发出宜人而甜美的香气，这种香气与玫瑰的香气不同，当花开到一定时候，其气味就带些辛辣味而令人感觉不适。

        花期：5月。
