Phytolith analysis of Chusquea ramosissima Lindm. (Poaceae: Bambusoideae) and associated soils

Chusquea ramosissima Lindm. is dominant in the understory of the Misiones province forests (Argentina); it colonizes open natural areas and gaps created by timber extraction. The aim of this study is to analyze both the phytolith assemblage produced by leaves, culms, and roots of C. ramosissima and...
