| Abstract: | Object To study the micro morphological characteristics of the leaf and stem epidermis of three species in Rabdosia (Bl ) Hassk Methods The leaf and stem epidermis of Rabdosia amethystoides (Benth ) Hara, R macrocalyx (Dann) Hara and R nervosa (Hemsl ) C Y Wu et H W Li were observed by scanning electron microscope (SEM) Results Some characteristics are same among three species, such as elliptical stoma and glandular scale which has four cells, but some characteristics are di fferent, such as the shape of epidermal cell, the distribution of nonglandular hair, the shape of stoma Conclusion The leaf and stem epidermal characteristics are obviously different among the three species, it provides the new reference to discriminate the plants of Rabdosia (Bl ) Hassk |
