| Objective: To research the Torenia fournieri in microscopic characteristics. Methods: The microstructure and powder characteristics of T. fournieri stem, leaf cross sections were studied by using paraffin sections and powder production. Results: The transverse section of the stem is square, four outward convex is triangle, the inner cortex is a layer of flat closely arranged cells, the phloem is narrow, the outer fiber is scattered, arranged in rows discontinuous, the four corners of the xylem are advanced, the catheter is radial alignment, the pith is wide; The leaves of the upper and lower epidermal cell anticlinal wall is curved, stoma could be found in it, a row of palisade tissue, the main vein vascular is half-moon sharp. Conclutiion: These characteristics can be used as the basis of microscopic identification of T. fournieri. |
