“…The SEM has proven invaluable for observations of the surface morphology of plant materials, primarily due to the improved depth of field and high resolution, which are unobtainable with the light microscope. This tool along with light microscope (LM) allows the use of more micro‐morphological data in taxonomic and morphogenetic studies of many plant families (Ahmad et al, ; Ashfaq et al, ; Bahadur et al, ; Esfandani‐Bozchaloyi & Zaman, ; Rashid, Zafar, Ahmad, Khan, et al, ; Rashid, Zafar, Ahmad, Malik, et al, ; Sufyan et al, ; Ullah, Zafar, Ahmad, Dilbar, et al, ; Ullah, Zafar, Ahmad, Shah, et al, ; Ullah, Zafar, Amhad, Sultana, et al, ). Nowadays, SEM is widely used to analyze leaf epidermal characteristics for taxonomic studies in many fern species (Bondada, Tu, & Ma, ; Chuang & Liu, ; Lee, ; Sen & Mukhopadhay, ).…”
