Microscopic Characteristics

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.

Powder, yellowish-brown; microscopically--numerous starch grains, 0.003-.02 Mm. (1/8325-1/1250') broad, colorless stone cells, numerous cellular reddish-brown fragments, calcium oxalate raphides; Saigon has many cork cells, Ceylon [Ed-Syn. verum in text] few or none, while bast-fibres of former are in groups of 2-20, of latter single and fusiform.
