To establish microscopic identification standards for four species from Uncaria genus.
The microscopic characteristics of transvers section and powder of these four species rattan were observed.
As for these four species from Uncaria genus, the microscopic identification of rattan transvers section could be made by the existence of cork cambium and pericycle in the cortex, and the location of phloem fiber and stone cells, while the powder identification could be made according to the existence of scalariform vessel and calcium oxalate crystal, and the quantity of stone cells.
The microscopic characteristics of rattan can provide information for identification of these four species from Uncaria genus.
建立钩藤属4种植物的显微鉴定标准。
观察这4种藤茎的横切面及粉末的显微特征。
对于钩藤属这4种植物，藤茎横切面的显微鉴定可依据皮层中是否存在木栓形成层和中柱鞘，以及韧皮纤维和石细胞的位置，而粉末鉴定可依据梯纹导管和草酸钙结晶的存在情况以及石细胞的数量。
藤茎的显微特征可为钩藤属这4种植物的鉴定提供依据。
