replaced synonym: Agrostis littoralis With. nom. illeg.

• Comment: nom. illeg., nom. superfl. as the name Agrostis littoralis With., nom. illeg., had been replaced in 1810 by Agrostis lutosus Poir. The epithet lutosus was available in Polypogon in 1816 and thus ought to have been adopted by Smith (ICN Art. 11.4 (Shenzhen Code, 2018)).
