f Nardus gangitis L., Sp. PL 53. 1753. Garden specimen, southern France, 

 (probably Montpellier). The specimen under this name in the Linnaean 

 Herbarium is from Montpellier, and is said by Munro (Jour. Linn. Soc. 

 Bot. 6: 35. 1862) to be Lepturus incurvatus Trin. (Pholiurus incurvus (L.) 

 Schinz and ThelL). The Linnaean citations refer to Andropogon and to 

 Rottboellia according to Trinius (Clav. Agrost. 346. 1822), except that to 

 Morison (PL Hist. 3: Sect. 8, tab. 3, last figure) which is a species of Ctenium. 

 Linnaeus gives as the origin of his plant "Habitat in G. Narbonensi" (Gallia 

 Narbonensis is southern France) . The application of the name N. gangitis is 

 too uncertain to be accepted for Ctenium aromaticum, as proposed by Druce.
