Abbas A. El-Ghamery
Abstract
anatomical features of stem and leaf have been studied on four endemic species collected from St.Katherine area, S Sinai, Egypt. viz. Silene leucophylla Boiss., S.oreosinaica, S,schimperiana and Bufonia multiceps is provided for the first time. Comparative study based on leaf and stem anatomical structure was made using both light (LM) and scanning electron microscopy (SEM). Cystoliths were found abundantly in both leaf and stem tissue in studied Silene taxa, absent in Bufonia multiceps. Stomata were mostly diacytic or both diacytic and anomocytic were also recorded. Surface view of epidermal cells were straight or undulated Epicuticular wax platelets have been observed on epidermal and guard cells of S.schweinfurthii and S.leucophylla.
