Taxon: Imperata cylindrica (L.) P. Beauv.
Genus: Imperata
Family: Poaceae (alt. Gramineae) subfamily: Panicoideae tribe: Andropogoneae.
Nomen number: 19864
Place of publication: Ess. Agrostogr. 8, 165, 177, t. 5, fig. 1. 1812 (Raeuschel, Nomencl. bot. 10. 1797, nom. nud.)
Comments:- Raeuschel gives no evidence his I. cylindrica, nom. nud. is based on Lagurus cylindricus L.
- his adoption of Imperata whose only prior species included L. cylindricus in synonymy isn't enough (ICBN Art. 33.3)
Name verified on: 15-Jul-1999 by ARS Systematic Botanists. Last updated: 29-May-2007
Species priority site is: Southern Regional PI Station (S9). Accessions:
