Taxonomic notes on some species of Deyeuxia Clarion ex Beauv. (Poaceae) from China

Abstract

Abstract: The taxonomy of some species of Deyeuxia Clarion ex Beauv. (Poaceae) from China is revised on the basis of herbarium materials and field observation of populations. Four species and one variety are reduced to synonymies, i.e., Deyeuxia pulchella var. laxa P. C. Kuo et S. L. Lu, D. gyirongensis P. C. Kuo et S. L. Lu and Calamagrostis megalantha Keng ex Keng f. to D. pulchella (Griseb.) Hook. f.; D. venusta Keng, Calamagrostis longiflora Keng ex Keng f. to D. flavens Keng. D. compacta Munro ex Hook. f. and D. holciformis (Jaub. et Spach. ) Bor are confirmed to be conspecific.
