Abstract:
Objective To study the leaf morphology and structure of Cyclocarya paliurus.Methods Foliar maceration,preparation of venation order,sectioning paraffin blocks,and scanning electron microscope were used to study the leaf morphology and structure.Results Cuticular papillates,glandular hairs,peltate scales,and non-glandular hairs presented on the leaf epidermis of C.paliurus.Anomocytic stomata were confined to the lower epidermis.Large cluster crystals existed in the uppermost layer of palisade cells.Midrib included one closed vascular system and one additional vascular strand.Secondary veins are semicraspedodromous and form marginal loops,tertiary veins are percurrent,quaternary veins form orthogonal or polygonal areoles filled up by branched and freely ended veinlets.Conclusion These structure characteristics are first reported and are useful for leaf identification of C.paliurus from other Juglandaceae plants.
