Medina, P.; P. Saldivia & L. Faúndez. 2019. Cyperus niger and C. fuscus (Cyperaceae) new records for Chile and contributions to the distribution of high Andean Cyperaceae. Darwiniana, nueva serie 7(1): 152-166.

The specimens of Cyperaceae present in the main Chilean herbaria (AGUCH, CONC, SGO, and ULS) are scarce and, consequently, information about the chorology of the family is deficient and incomplete at the national level. This work reports two new records of the genus Cyperus for Chile: Cyperus niger, collected in the basin of middle Conay river, in the Atacama Region; and Cyperus fuscus, which is adventitious in America, found near the mouth of the Bío-Bío river, in the Bío-Bío Region. Additionally, new records, localities, and distribution maps that complement the chorology of the following Andean species: Amphiscirpus nevadensis, Eleocharis tucumanensis, Zameioscirpus gaimardioides, and Z. muticus in Chile are reported, and the morphology of the latter two discussed in taxonomic terms. Finally, an artificial key to the genera of Cyperaceae in Chile is presented.
