Note
Shipping list no.: 98-0304-P. Silica bodies from over 200 species of Neotropical grasses comprising 80 different genera from all currently recognized subfamilies have been isolated from plant tissue and have been described. Silica-body shapes are significant at varying taxonomic levels, from the family to the genus. The Bambusoideae, especially, contribute large numbers of tribal- and genus-specific forms. Significant correlations are found between phytolith shape and the source plant's taxonomic relationships and postulated phylogeny. Disarticulated short-cell phytoliths occurring in ancient soils and sediments can be used to make identifications of certain taxa in the Poaceae below the level of family. Silica bodies observed in fossil grasses may elucidate the evolutionary history of the Poaceae. - Content source: DLC
