[Wikipedia] Taxonomy: Scottish botanist George Don described Acacia cultriformis in 1832,[2] calling it the cultriform-leaved acacia.[3] The species name relates to the knife-shaped phyllodes.[4] Queensland botanist Les Pedley reclassified the species as Racosperma cultriforme in 2003, in his proposal to reclassify almost all Australian members of the genus into the new genus Racosperma;[5] this name is treated as a synonym of its original name however.[2] Common names include knife-leaf (or -leaved) wattle, golden glow wattle, half-moon wattle or dog-tooth wattle.
