<strong>DESCRIPTION</strong>
<strong>a) Macroscopic</strong>
Root-rough, fissured longitudinally, corky and soft, externally yellowish-grey
while internally white, central core cream coloured, bark easily separated from xylem,
odour, characteristic: taste, bitter and acrid.

<strong>b) Microscopic</strong>
Transverse section of root shows outer most cork tissue consisting of 4-8 rows of
tangentially elongated and radially arranged cells followed by 3-6 rows of moderately
thick-walled, irregular cells of secondary cortex devoid of calcium oxalate crystals and
starch grains, cortex composed of large polyhedral parenchymatous cells containing
abundant rounded starch grains, some cortical cells contain rosette crystals of calcium
oxalate, scattered laticifer cells with brown contents, phloem consists of sieve elements
and phloem parenchyama, sieve tubes thick-walled, cells more prominent towards inner
region of phloem traversed by uni to tetraseriate medullary rays, phloem cells contain
crystals of calcium oxalate, starch grains and laticifers similar to these found in cortex:
cambium present just within the phloem consisting of 2-5 rows of thin-walled,
tangentially elongated cells xylem forms the central part of root composed of vessels.
11tracheids, fibres and xylem parenchyma, vessels present throughout xylem region and
arranged radially in groups of 2-7, sometime single vessels also occur, usually
cylindrical having bordered pits on their walls, xylem fibres long, lignified with wide
lumen, tapering on ends and have simple pits on walls, medullary rays 1-4 seriate and
triseriate in outer region and uni or biseriate in inner region: cells of medullary rays
radially elongated, filled with starch similar to those present in cortical cells.
