Objective: To establish microscopic identification standards for four species from Uncaria genus.
Methods: The microscopic characteristics of transvers section and powder of these four species rattan were observed.
Results: 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.
Conclusion: The microscopic characteristics of rattan can provide information for identification of these four species from Uncaria genus.
