Based on herbarium and field observations, a new species, Holcoglossum nujiangense , is described and illustrated. It is morphologically similar to Holcoglossum sinicum and H. weixiense . Holcoglossum nujiangense differs from H. weixiense by smaller flowers with broadly rhombic midlobe and from H. sinicum by its broadly rhombic midlobe, papillose spur and notable callus on the disc. The chromosome number of this species was found to be 2n=38. The pollinator for this new species was Micraphis andreniformis Smith that carried the pollinia of Holcoglossum nujiangense on its head. The visiting behavior of the pollinator is food‐search kind, although there is no obvious nectar in the spur.
