The present list is the third to be published in the series Repatriation of Kew herbarium data for the Flora of Northeastern Brazil. 1392 specimens (58 types) from NE Brazil were databased and repatriated between 2002 and 2004, after being identified by leading authorities or using the most recently published revisions or monographs, and/or by comparison with authoritatively named herbarium vouchers. In total 191 species are recorded in 24 genera for the whole of the Cyperaceae. These are alphabetically arranged and sorted by state, collector and number. In addition to this main list, a full exsiccatae list (an alphabetical list of collector and collector`s number) allows curators, students and researchers to name a duplicate collection lodged in any herbarium in the world to be checked against the determination of that collection at Kew.
