| Cinnamon (powdered bark) (Cinnamomum aromaticum) Lauraceae. (Cassia Cinnamon)Rather short, thick walled bast cells sclerenchyma with cell walls unequally thickened parenchyma cells with compound starch granules; cells with numerous small prismatic crystals; large resin bearing cells; cells of outer bark suberized and with reddish brown contents. Cassia bark contains relatively more starch than do the other varieties of cinnamon barks and relatively less bast tissue.

| Ceylon Cinnamon (powdered bark) (Cinnamomum verum) B., Lauraceae. (Cinnamomum Zylanicum)Histology much like that of Cassia Cinnamon; bast cells are more abundant and the cells of the outer cork wanting; starch less abundant. It is possible to distinguish this cinnamon from the other two by the larger sclerenchyma cells and absence of outer cork and epidermal tissues.
