Towards improved detection and identification of crop by-products: Morphometric analysis of bilobate leaf phytoliths of Pennisetum glaucum and Sorghum bicolor

Furthermore, one P. glaucum population that was grown in a rather different climate than the others also shows different bilobate morphometry results. This difference between P. glaucum populations points to phytolith morphometry possibly being influenced by environmental settings. Moreover, it has implications for sampling strategies of similar research and the validity of morphometric identification criteria based on data from few reference populations or reference populations from a single region.
