Three New Natural Hybrid Species Related to Cymbidium qiubeiense

There are three natural hybrid species, Cymbidium x purpuratum, C. x latifolium and C. x uniflorum, which are hybridized by C. qiubeiense with C. kanran, or C. lancifolium or C. serratum respectively, were described and illustrated. C. qiubeiense was found growing together with C. kanran, or C. lancifolium, and or C. serratum in the natural habitat. C. x purpuratum leaf quantity of plants, leaf shape, and sepals are similar to C. kanran ; the bracts, petals and lips are similar to C. qiubeiense. The leaves and peduncle of C. x latifolium are similar to C. lancifolium, and its flowers are similar to C. qiubeiense. The leaf shape and peduncle of C. x uniflorum are similar to C. qiubeiense, its flowers shape and leaves non-articulate are similar to C. serratum. A key to C. qiubeiense, C. kanran, C. lancifolium, C. serratum and their natural hybrid species were provided.
