Species 1 (v. 22), regionis Mediterranez incola. Kunth, Euwm. Pl.i.249. Desf. Fl. Atl. t. 33, 
34 (Arundo). 
Genus Arundini quam maxime affine, differt glumis rigidioribus -nervibus, et ovario caryopsique 
apice hirsutis. Rhachilla inter flores penicillo pilorum instructa et styli breves etiam in arundine 
4nadagascariensi observantur.

ete., et ab auctoribus in plures dividitur, omnes tamen unius varietates videntur. Kunth, Enum. 1. c., 
et auctores plerique stylos PAragmitidis uti omnium Arundinearum elongatos dieunt, quod tamen in 
sola Arundine Donace observatur. Kunth ipse in Rev, Gram. l.c, stylos breves descripsit et
