Microscopic Identification of Crotalaria assamica

Objective To study the Microscopic character of Crotalaria assamica Benth.Methods Microscopic identification were adopted.Results The xylem of the root is broad and There are a lot of wood fiber in xylem;There are many nonglandular hairs in stem epidermis,the vascular bundle is big or small,and the pith is empty;The vascular bundle looks like a crescent and there was vascu-lar bundle sheath outside in leaf,lower epidermis is covered with nonglandular hairs.It contain fibre bundle,vessel and nonglandular hairs in the powder.Conclusion These results can be used to provide the scientific evidence for the establishment of standard for quali-ty control and further study.
