Cyperus difformis Linnaeus, Centuria II Plantarum: 6. 1756.
"Habitat in India." RCN: 383.
Lectotype (Tucker in Syst. Bot. Monogr. 43: 50. 1994): Herb. Linn. No. 70.10 (LINN) .
Current name: Cyperus difformis L. ( Cyperaceae).
Note: Lye (in Nordic J. Bot. 1: 57. 1981) stated that the type was in LINN but did not distinguish between sheets 70.10, 70.11 and 70.12. As they are evidently not part of a single gathering, Art. 9.15 does not apply.
