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.

Saigon Cinnamon (powdered bark) (Cinnamomum loureiroi), Lauraceae. (Vietnamese Cassia)Histology much like that of Cassia; bast cells somewhat larger. Starch and sclerenchyma cells much as in Cinnamon aromaticum. Numerous small epidermal cells with thickened walls. Resin cells and crystals as in the other cinnamons.
Cinnamomum spp. (bark)The most distinctive tissue elements are the thick walled fiber as well as the large resin cells showing dark red contents.400X Acidified chloral Hydrate Soln.

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.
