03BA863BFFCBFFB9FF20FB0FA11DF7B7.taxon	diagnosis	Pleione × maoershanensis is a hybrid intermediate between P. pleionoides and P. hookeriana.

03BA863BFFCBFFB9FF20FB0FA11DF7B7.taxon	etymology	Etymology: — Named after the highest mountain in South China (Maoer Shan), where this natural hybrid was discovered.	en	Zhang, Wei, Qin, Jiao, Yang, Rui, Yang, Yi, Zhang, Shi-Bao (2018): Two new natural hybrids in the genus Pleione (Orchidaceae) from China. Phytotaxa 350 (3): 247-258, DOI: 10.11646/phytotaxa.350.3.4, URL: http://dx.doi.org/10.11646/phytotaxa.350.3.4
03BA863BFFCBFFB9FF20FB0FA11DF7B7.taxon	distribution	Distribution and habitat: Known only from the type locality. This hybrid grows on humus-covered rocks in forests or cliffs at forest margins, mixed with P. hookeriana at an elevation of 1300 – 1600 m. The hybrid was found only on rocks while P. hookeriana grows both on rocks and moss-covered trunks or branches of Lithocarpus hancei (Bentham) Rehder in a Tsuga / Rhododelldron forest from 1300 to 2000 m. The other parent, P. pleionoides, was not seen during our brief exploration of Maoer Shan. However, we collected samples of that species from Yinzhulaoshan Nature Reserve in Ziyuan County, a place less than 50 km away from Maoer Shan. The variation of lip morphology of P. × maoershanensis implies backcross between the hybrid and the parents (see Fig 2). This hybrid has also been raised artificially by Paul Cumbleton and registered as “ Pleione Potto ” (P. chunii × P. pleionoides) in 2009 at Royal Horticulture Society.	en	Zhang, Wei, Qin, Jiao, Yang, Rui, Yang, Yi, Zhang, Shi-Bao (2018): Two new natural hybrids in the genus Pleione (Orchidaceae) from China.
