DESCRIPTION
a) Macroscopic
Roots vary in length and are 1 to 1.5 cm thick; slender, cylindrical, dark brown or blackish; rough due to fine longitudinal ridges and wrinkles running sinuously lengthwise; thicker roots show a few transverse cracks, fissures and longitudinal wrinkles with remnants of rootlets and a few lenticels; cork easily peelable; fracture, short and fibrous; odour, slightly aromatic; taste, sweet and astringent.
b) Microscopic
Shows thin cork consisting of 4 to 14 layers of thin-walled, rectangular to tangentially elongated cells, arranged radially; cork cambium single layered, followed by a wide zone of secondary cortex composed of polyhedral, oval to tangentially elongated cells having fibres in single or in groups of two to ten; fibres long, thick-walled but very occasionally appear also as elongated stone cells; secondary phloem wide consisting of sieve elements, phloem parenchyma, fibres and a few crysta1 fibres, and traversed by phloem rays; phloem fibres occur in small groups or rarely in singles, somewhat similar in shape to those of secondary cortex with comparatively thicker walls; crystal fibres elongated, thick-walled and divided into chambers, usually 7 to 17 in number, each chamber containing a prismatic crysta1 of calcium oxalate; medullary rays urn-to triseriate; cambium 2 to 4 layered; secondary xylem composed of vessels, tracheids, fibre-tracheids, fibres and parenchyma and traversed by xylem rays; vessels with bordered pits, and filled with tyloses; tracheids long and narrow having bordered pits, and moderately thick-walls; xylem parenchyma usually rectangular in shape with pitted walls but some of the pits become T or Y shaped with reticulate thickening; xylem elements thick-walled and lignified; simple and compound starch grains found in abundance in all parenchymatous cells simple being elliptical to oval, measuring 3 to 19 n in dia., with central hilum and compound with 2 or 3 components.
Powder – Light grey; shows fragments of cork cells, vessels having bordered pits, tracheids, fibres, prismatic crystals of calcium oxalate, starch grains numerous, simple and compound, elliptical to oval, measuring 3 to 19 n in dia., with central hilum and compound with 2 or 3 components.
