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 (E. A. 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 (Melbourne ICN Art. 41.4)
Name verified on: 15-Jul-1999 by ARS Systematic Botanists. Last updated: 06-Sep-2013
Species priority site is: Plant Genetic Resources Conservation Unit, Griffin, GA (S9).
