Asian rice is an important grain, not only in its homeland but in many areas of the world. Identifying rice in the archaeological record is a challenge, especially in the moist tropics, where organic materials preserve only when charred. Phytolith analysis, the identification of opaline silica bodies, provides an alternative method for identifying this important crop. Results of our research suggest that Oryza contributes phytoliths that are genus-specific, that bulliform characteristics alone do not permit separation of wild and domesticated Oryza in regions where species overlap, and that a number of phytolith types, especially silicified glumes, show promise for separating wild from domesticated forms. With further research it should be possible to identify rice through its phytolith assemblage in archaeological soils in the heartland of its domestication and use. © 1995 New York Botanical Garden, Bronx, NY 10458 U.S.A.
