Macroscopic Characteristics

Plants: Handsome evergreen trees, 6-9 M. (20-30°) high, truck .3-.5 M. (12-18') thick, young twigs slightly quadrangular; leaves coriaceous, 3-5-nerved, but only midrib reaches apex, bright glossy-green above, glaucous beneath, 10-20 Cm.

(1/50-1/8') thick, light brown, dark purplish-brown with grayish patches of folaceous lichens and numerous bud-scars, finely wrinkled, especially that of younger twigs, otherwise rough from corky patches surrounding the lenticels; inner surface reddish-brown, granular, slightly striate; fracture short--inner bark porus from large oil and mucilage cells, and separated from the outer by a layer of stone cells.

Microscopic Characteristics

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.

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.
