From the CO2Science Archive: Wallaby grass, formally known as Rytidosperma richardsonii (Cashmore) but formerly formally known as Austrodanthia richardsonii (Cashmore) and formally before that Danthonia richardsonii Cashmore. We don’t know why a grass would change its name so often since it can hardly be hiding from the law. Rather, under its tongue-friendly long-standing moniker of Wallaby grass it’s also lawn-friendly, a popular low-maintenance option for front and back yards in Australia. In 1999 there were 9 experiments reporting an average growth boost of 25% from an extra 300 ppm CO2 in the air. So it will be reaching higher, or lower since it’s down under, with all the extra CO2 now available to it.
