Selereids and fibre of the pericycle. 8. Part of the cork in sectional view showing the alternating layers of thin-walled and thicker walled cells. (Source: Jackson and Snowdon, 1990.)

Wood anatomy

Pearson and Brown (1932), Dadswell and Eckersley (1940) and Stern (1954) carried out wood anatomical studies on Cinnamomum species. Stern (1954) studied the wood anatomical features of C. camphora and C. porrectum and gave the following description of xylem features of C. camphora: growth rings distinct, pores 17—35 in a square mm, angular to circular, tending to angularity, vessel wall thickness 2—4.5 fx, tyloses
