Cymbidium Sw. has extremely high ornamental value. It has been cultivated for more than a thousand years in China. Tibet is rich in the resources of Cymbidium. Knowing the background resources of Cymbidium can provide basic information for the cultivation of ornamental horticultural varieties in the future. This research reports four new record species of Cymbidium (Orchidaceae) in Tibet: Cymbidium cyperifolium Wall. ex Lindl., C. devonianum Paxton, C. goeringii (Rchb. f.) Rchb. f., C. mastersii Griff. ex Lindl.. Among them, C. cyperifolium and C. faberi are similar, but the petals and sepals of C. cyperifolium are not striped, and the leaf are entire. C. devonianum is special in the Cymbidium, and the plant has only 2-4 leaves. The large number of flowers can be distinguished from other species of this genus. C. goeringii is similar to C. faberi, but it is easy to distinguish them by its short scape and obvious pseudobulb. The flowers of C. mastersii and the two bright yellow longitudinal ridges of the lip are similar to C. elegans, but the pseudobulb of C. mastersii is elongated into a stem shape and the leaves are narrow, two longitudinal ridges of the labial disc meet in the middle. Descriptions and photographs for diagnostic characters are provided. The discovery of the new record species has expanded the record of orchids in Tibet, and would provide new information for the cultivation and domestication of Tibet’s orchids and the cultivation of horticultural varieties in the future.
