Abstract
Identification of phytoliths from Bouteloua eriopoda Torr. (black grama) roots was based on repetitive size and shape, low density, acid insolubility, and lack of crystallinity. Refractive index, and contents of water and SiO2 support identification as opal. These distinctive rectangular phytoliths were the most commonly observed form in the A horizons of several soils and paleosols.Keywords
