Notes on Carex (Cyperaceae) from China (II): a taxonomic revision of sect. Radicales (Kük.) Nelmes

Section Radicales (Kuk.) Nelmes comprises nearly 15 species in Carex subg. Carex (Cyperaceae) and is mainly distributed in the Pan-Himalaya region, with a few species extending to the Guangxi and Hainan provinces of China and Burma. A taxonomic revision of sect. Radicales in China is proposed and 12 species with two varieties are recognized. Carex pseudomitrata X. F. Jin & Cen is described as a new species and C. caudispicata var. longiutriculata X. F. Jin is described as a new variety. Carex anningensis is reduced to synonym of C. caudispicata , and C. chuiana to C. radicalis . Carex funhuangshanica and C. speciosa subsp. dilatata are respectively reduced to synonyms of C. speciosa and C. speciosa var. courtallensis .
