Microparticles of Silica (Phytoliths) Found in Cannabis sativa from Khabarovsky Krai (Russia)

First data on morphology of phytoliths was obtained for leaves, body, and inflorescence of Cannabis sativa found in 2 regions of the Khabarovsky region (Khabarovsk City and Bikinsky District). Optical microscopy revealed 5 phytoliths morphotypes in the scape, inflorescence, and in the leaves of the cannabis: shapeless, oval, segmented oval, club-shaped, and spikes. Size of phytoliths from various plant’s parts is found to be uniform, but their morphometry changes with respect to ratio among shapes. Shapeless dominate in the scape (68%), inflorescence, and in leaves (31.33%). Spikes are found in inflorescence (32%) as well as in scape (30%) and in leaves (10.6%).
