The epidermal structures of six species of Aspidiaceae were observed under light microscope.The results showed that their epidermal cells are irregular with their anticlinal walls undulate or sinuate.There are six types of stomatal apparatus,i.e.Polocytictype,Copolocytictype,Axillocytictype,Coaxillocytictype,Aisocytictype and Anomotetracytictype.The components of stomatal apparatus are polymorphic,and all the stomatal apparatuses only occur in the lower epidermis,and the stomatal indexes are similar.Raphides and monocrystals are visible in the upper and lower epidermal cells.But the six species of Aspidiaceae are different in the size of epidermal cells,trichome production,the size of stomata and stomata density and crystal types.
