Abstract
When grown under conditions of low relative humidity, the C<inf>3</inf>–C<inf>4</inf> intermediate <it>Panicum milioides</it>, as well as the C<inf>3</inf> grasses <it>Triticum aestivum</it> and <it>Poa pratense</it>, exhibited δ13C values which were up to 2–7&percnt;o less negative than the δ13C values of the corresponding plants grown at high relative humidity. At both humidity levels, there was no evidence of a substantial contribution of phosphoenolpyruvate carboxylase to carbon gain in <it>Panicum milioides</it>
