Paphiopedilum ×yingjiangense Z. J. Liu & S. C. Chen (Acta Bot. Yunnan. 29: 289. 2007) was recently described as a natural hybrid from W Yunnan (Yingjiang). In the protologue, P. villosum and P. wardii were suggested as the putative parents. However, a more likely parentage is P. spicerianum and P. wardii.
