The study about leaf anatomy of Bilberry (Vaccinium korinchense RILD.)  at  altitude gradient on the Talang Mountain has been carried out in October to December 2015. The goal research is to compared that leaf thick tissues Bilbellry at altitude gradient. The sample were collected at Talang Mountain. The research used survey method and purpossive sampling with five altitude gradient (2200-2529 meter above sea level). Leaf section was maked  at the Plant  Structures developments Laboratory, Department Biology, Faculty of Mathematics and Natural Sciences, Andalas University. Data analysis used Kruskal-Wallis test. The results showed that leaf thickness, palisade and spongy thickness various between altitudes is sequentially 434-685 ?m, 183-322 ?m and 175-283 ?m . While epidermis thickness and cuticle thickness did not differ significantly between altitudes.

The stomatal features of the leaves of several species of various life forms that grow around the cement factory are investigated with the aim of examining the anatomical modifications of the leaves which increase their tolerance and survival in the presence of cement dust pollution. In addition, the chlorophyll content in the leaves has also been examined. In comparison, the same study has also been carried out for the composition of the same species in unaffected locations. Three different life forms of the plant were investigated over two sites: trees, represented by Polyalthia longifolia, Acacia auriculiformis, Persea americana, and Mangifera indica; shrubs by Syzygium myrtifolium, and Ixora javanica; and herbs by Rhoe and Aglaonema. The average stomata density in the affected area was 173.16 /mm2, while it could reach 244.96 /mm2 at the control site. The same trend was also shown by the chlorophyll content. The Independent T-test revealed a significant difference (p-value = 0.037). Adaptability in terms of having chlorophyll content from all three life forms at different sites was also available in this discussion. Herbs has the greatest difference between sites (0.33 μg/mL), followed by shrubs (0.31 μg/mL) and then trees (0.2 μg/mL). The Two way ANOVA test showed that both life forms and sites significantly influenced the content of chlorophyll (p-value = 0.00). However, there was no interaction between sites and life forms in influencing chlorophyll content (p value=0.652). In conclusion, In all three life forms, either stomatal density or chlorophyll content decreases with pollution.

Nepenthes or pitcher plant is one of the most exotic plants in the world. There are 82 species of Nepenthes in the world, and very few studies concerning salinity stress have been carried out. We have found one species of pitcher plant that was exposed to seawater, namely Nepenthes gracilis Korth. Sixty-eight individuals were exposed to seawater and the rest were not. Observing and measuring morphological characters and anatomical characters have been done to these two sample groups in order to reveal the adaptation expression to the salinity stress. Statistical analysis has also been carried out between both groups. Two samples showed that they have significant differences in the size of pitcher and leaf. The ones which were exposed to seawater had smaller pitchers and leaves than others. The exposed seawater pitcher plant also has thicker leaves and palisade than others. Additionally, salinity exposure tended to decrease the stomatal density. The possible reason for this pattern was discussed in this study.
