Cytological Studies on Cyperaceae in the Nepal Himalaya I. Chromosome Counts of 14 Species Collected from the Manaslu Himalaya, Central Nepal

Abstract

Chromosome numbers of 14 species of Cyperaceae recently collected from the Manaslu Himalaya in Central Nepal are presented. Chromosome numbers for Carex inanis Kunth (2n = 42), C. rufulistolon T. Koyama (2n = 46), and C. speciosa Kunth (2n = 44) are reported here for the first time. Our findings of 2n = 40 for Blysmus compressus (L.) Panz. ex Link, 2n = 46 for C. filicina Nees, and 2n = 32 for Isolepis setacea (L.) R. Br. differ from previously published reports. Chromosome numbers of C. atrofusca Schkuhr subsp. minor (Boott) T. Koyama (2n = 48), Cyperus haspan L. (2n = 26), Eleocharis congesta D. Don (2n = 20), Fimbristylis dichotoma (L.) Vahl (2n = 20), F. littoralis Gaudich (2n = 10), F. schoenoides (Retz.) Vahl (2n = 10), Lipocarpha chinensis (Osbeck) Kern (2n = 26), and Schoenoplectus juncoides (Roxb.) Palla (2n = 74) coincide with past reports.
