tarjonnut eFloras
The name
Aira indica was originally given as
"Aira spicata," but this was corrected by Linnaeus in the errata on the final page [1231] of
Species Plantarum.
The combination "Sacciolepis indica var. angusta (Trinius) Keng" (Fl. Ill. Pl. Prim. Sin. Gram. 662. 1959) was not validly published because a full and direct reference to the basionym was not provided.
