Padang Panjang city located at an altitude of 650 to 850 meters above sea level, so that weather cold and cool. Temperatures range from 17 {\textdegree}C to 26.1 {\textdegree}C and with 3,295 mm/ year of rainfall. This area is rich in the diversity of flora and fauna. Pteridophyta is one of the flora that has a unique diversity of species and has the potential for tremendous utilization such as ornamental plants, medicines and vegetable plants. The study was conducted in the Lubuak Mato Kuciang area of Padang Panjang City, West Sumatra, which is currently being developed for tourism. The aim of this study obtain collect data and information about the diversity of ferns in Lubuk Mato Kuciang. The activities of the study are conducted to collect species as much as possible. Identification of fern species was carried out in the Laboratory of Educational Science. Mathematics and Science Faculty. Padang State University. The identification of flora was analyzed descriptively. The identification species results were obtained through descriptive analysis. The results of this study obtains that there were 21 species of fern that include 11 families. They were namely; Selaginellaceace including Selaginella sp, Selaginella plana Hieron and Selaginella wildenowii; Lomariopsidaceae family including Neplholepisbiserrata; Pterisvittata L; Adiatumpedatum; Cyatheaceae family, including Cyatheacontaminans; Gleicheinaceae including Gleichenialinearis; Marrattiaceae family including Marrattiafraxinea; Lindsaeaceae family including Sphenomeris chinensis; and Dryopteridaceae family including Nephroletis cordifolia.

Objective: Various traditional systems of medicine enlightened the importance of Psychotria rubra (Lour.) Poir to have a great medicinal value. The present study was carried out to provide a scientific basis of the identification and the authenticity of Psychotria rubra (Lour.) Poir with the help of pharmacognostic parameters, which is not done before. Methods: Roots, stems, and leaves of P. rubra were collected for Pharmacognostic studies involving macros, microscopic evaluation, histochemistry and physicochemical parameters analysis like Ash value, Moisture content, Fluorescence analysis and Thin Layer Chromatography et al. Results: Transverse section of root was found like stone cells, calcium oxalate crystal and vessels in circular shape. Transverse section of stem showed the presence of lenticels and stone cell bands. Transverse section of leaf vein revealed the presence of shaft type of porosity. Powder microscopy revealed the presence of cork cells, stone cells, crystals and resin, fibers, needle crystal beam, thread tracheid and scalariform tracheid. Phytochemical investigation was found like alkaloids, flavones, carbohydrates, saponins, tannins and volatile oils. Results obtained in physicochemical parameters like Total ash value, acid insoluble ash and moisture content were 9.77\%, 0.68\% and 1.28\%, respectively. The leaching degree of P. rubra was higher in ethanol(75\%, v/v) and methanol solutions than that in chloroform, petroleum ether, and tetrachloromethane solutions. Thin Layer Chromatography (TLC) of the extract revealed 4 spots with the Rf values 0.47, 0.46, 0.46, 0.47 with the solvent system of chloroform: methanol: water: formic acid(7:3:1:0.1). Conclusion: The observations confirmed that P. rubra has an obvious Pharmacognostic characteristics, which will be useful towards providing a reliable basis for identification, purity, quality and classification of the plant.
