Abstract: Preliminary anatomical structure of leaf from Lonicera maackii was studied by the methods of barehanded section in order to provide the basis for anatomy, systematic and pharmacognosy. The results show that: leaf of L.maackii is bifacial leaf , the upper and lower epidermis are 1 layer, the stomata only exist in lower epidermis, stomatal index is 14.3%~25%,most stomata are anomocytic type, palisade tissue is 1 layer with a lot of chloroplasts, there are cluster crystal of calcium oxalate in spongy tissue ,the main vein of leaves is collateral vascular bundle. There is collenchyma in cortex. The characters mentioned aboved show leaf of L.maackii adapted well to the physiological function and ecological environment.

Key words: leaf of Lonicera maackii, original plant identification, morphological identification, anatomical structure
