7. Iris psammocola Zhao (1992: 181) .

Holotype:— CHINA. Lingwu: Baijiatan , 10 April 1959. Anonymous and no number (NETU). Note: I have not seen the type specimen of I. psammocola . Dr. Mingli Zhang, who kindly helped me in searching the specimen, got an information from Dr. Ming-Zhou Sun (the Herbarium of NE Normal University, Changchun, Jilin Province) that “the type of Iris psammocola has not been found; probably it was lost while the herbarium was moved to a different room several years ago”. So, we can judge its characteristics only after the original description and illustration in the protologue ( Zhao 1992: 182).
