(Laurales) JF - Our Nature JA - Our Nature VL - 19 IS - 1 SE - Articles DO - 10.3126/on.v19i1.41212 UR - https://nepjol.info/index.php/ON/article/view/41212 SP - 1-9 AB - <p>The comparative leaf morphology and anatomy of ten species of family Calycanthaceae have been studied. Leaf anatomy is very comparable to each other in cell shape and their arrangement. Collected leaves were preserved in FAA and alcohol series were applied for LM and SEM. The layer of epidermis is two in <em>Idiospermum </em>and one in rest of other genera. The structure of vascular bundle is V-shape in <em>Sinocalycanthus </em>and <em>Calycanthus </em>whereas U-shape in <em>Idiospermum </em>and <em>Chimonanthus</em>. The density of trichome is higher in <em>Calycanthus </em>than other genera. The presence of trichome, stomata, epidermal layer, density of trichome and stomata, and leaf surface are represented the distinction among the genera. The adaxial surface of <em>Idiospermum</em> and <em>Sinocalycanthus </em>are smooth whereas of <em>Calycanthus </em>and <em>Chimonanthus </em>are rough. The crystals are present in <em>Calycanthus</em>, <em>Sinocalycanthus </em>and <em>Chimonanthus </em>whereas absent in <em>Idiospermum</em>. The shape of the vascular bundle, density of trichome, epidermal layer, and crystals play important role in the phylogenetic relationship of Calycanthaceae.</p><p><strong><em>&nbsp;</em></strong></p> ER -
