? Nardus gangitis L., Sp. PI. 53. 1753. 

 Garden specimen, southern France, 

 (probably Montpellier). The specimen 

 under this name in the Linnaean Her- 

 barium is from Montpellier and is said 

 by Munro (Jour. Linn. Soc. Bot. 6: 35. 

 1862) to be Lepturus incurvatus Trin. 

 (Parapholis incurvus (L.) C. E. Hubb.). 

 The Linnaean citations refer to Andro- 

 pogon and to Rottboellia according to 

 Trinius (Clav. Agrost. 346. 1822), ex- 

 cept that to Morison (PI. 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.
