Fibers of the two cultivars of Sansevieria trifasciata and images of lignin and cellulose in fibers. (a) Crude fibers from cvs Lorentii (left) and Hahnii (right) collected from 3 or 4 adult leaves. (b) Micrograph-based drawing of cells in cross section of S. trifasciata adult leaf showing the distribution of the different fiber types. (c) Confocal laser scanning micrographs of fluorescence of lignin (autofluorescence) and cellulose (stained with propidium iodide) in the different fiber types.
