On the identity and occurrence of Cyperus pseudoalatus and Cyperus richardii (Cyperaceae) in India

Abstract

Cyperus pseudoalatus (Wad.Khan & R.D. Taur) Kottaim. (Kyllinga pseudoalata Wad.Khan & R.D.Taur) is reduced to a synonym of Cyperus tenuifolius (Steud.) Dandy, with critical discussion. Based on a careful scrutiny of the protologues and type images of Kyllinga bulbosa P.Beauv., K. tenuifolia Steud. and Cyperus richardii Steud., it is confirmed that the plants reported earlier from India and Sri Lanka as Kyllinga bulbosa (Cyperus richardii) are likely misidentified and represent Cyperus tenuifolius.
