Neotype: French Guiana, ”Trou Caimans”, Cremers, Escobar & Feuillet 12446 (US) Isoneotypes; (B, CAY, NY, P, U) Strong & Kral in Taxon 48: 387, 1999.

On wet ground; river sides; rice fields; Distribution: From Iraq to India, China, Japan, Philippines, Malesia, Africa S of Sahara, Puerto Rico (distribution insufficiently known); pantropical, esp. rice weed.

It must be made clear, that here the well founded proposal by Strong and Kral (l.c.) to conserve Scirpus miliaceus L. with the type is followed and the name F. miliacea (L.) Vahl is being used in its traditional sense. In Fl. Iranica (Kukkonen 1998) the name F. littoralis Gaud. was applied for this species. S.T. Blake (Journ. Arnold Arbor. 35: 217, 1954) lectotypified S. miliaceus L. with LINN 71.41, which represents F. quinquangularis (Vahl) Kunth, the following species.
