	<span style="line-height:1.5;">In this study the anatomical characters of the stems and leaflets of </span><i style="line-height:1.5;">T.
longipetalous </i><span style="line-height:1.5;">Viv</span><i style="line-height:1.5;">.</i><span style="line-height:1.5;">,</span><i style="line-height:1.5;"> T.
pentandrus </i><span style="line-height:1.5;">Benth</span><i style="line-height:1.5;">. </i><span style="line-height:1.5;">and </span><i style="line-height:1.5;">T. terrestris </i><span style="line-height:1.5;">L. were compared to
assist as a relevant source of information and contribute towards the standards
to dispose the quality and identity of these plants to avoid adulterations.
Transverse sections of the stems and leaf lets of the three species were done
using wax method technique. The anatomical structures of the three studied
species are very similar. The stems are formed of one layer epidermis,
parenchymatous cortex, pericyclic fibers above the collateral vascular bundles,
primary and secondary xylems and phloems, narrow medullary rays and wide
parenchymatous pih. The densities of the epidermal hairs in the stems are found
to be larger in</span><i style="line-height:1.5;"> T. pentandrus</i><span style="line-height:1.5;"> followed by</span><i style="line-height:1.5;"> T. longipetalous</i><span style="line-height:1.5;"> and lastly </span><i style="line-height:1.5;">T. terrestris</i><span style="line-height:1.5;">. There are sclrenchymatous fibres in the pith of </span><i style="line-height:1.5;">T. longipetalous </i><span style="line-height:1.5;">and </span><i style="line-height:1.5;">T. pentandrus</i><span style="line-height:1.5;"> but not in </span><i style="line-height:1.5;">T. terrestris</i><span style="line-height:1.5;">. The leaflets are
dorsiventral, showing kranz structure and different types of hairs. The densities
of the epidermal hairs in the leaflets are found to be larger in </span><i style="line-height:1.5;">T. longipetalous</i><span style="line-height:1.5;"> followed by </span><i style="line-height:1.5;">T. pentandrus</i><span style="line-height:1.5;"> and lastly </span><i style="line-height:1.5;">T. terrestris</i><span style="line-height:1.5;">.</span>
