 The easy propagation of "B. vulgaris" explains its seemingly wild occurrence.The average chemical composition is cellulose 41–44%, pentosans 21–23%, lignin 26–28%, ash 1.7–1.9%, and silica 0.6–0.7%.The bambusoid taxa have long been considered the most "primitive" grasses, mostly because of the presence of bracts, indeterminate inflorescences, pseudospikelets (units of inflorescence or flower clusters and glumes or leaf-like structures in woody bamboos that is similar to spikelets or clumps of grass), and flowers with three lodicules (tiny scale-like structure at the bottom of a florets or clump of grass flowers, found between lemma, the lowest part of spikelets, and sexual organs of the flower), six stamens, and three stigmas.
