The purpose of this study was to describe the stomata found in pulai, mahang, saga, white meranti and ketapang plants in the green space area. This study uses a descriptive method to describe stomatal characteristics such as stomatal type, stomata size and number of stomata in perennials, mahang, saga, ketapang and white meranti. The study was conducted in two green open areas, namely the Untara Sylva Arboretum and in the public green open area. Length of stomata observation for 2 weeks. Overall the results of the observations obtained 4 (four) types of stomata that are the same in the two regions. The types of stomata are anisocytic in Pulai (Alstonia scholaris), anomosytic in mahang (Macaranga pruinosa), parasitic in saga (Adenanthera pavonina), pickled on white meranti (Shorea bracteolata), anisocytic on ketapang (Terminalia cattapa). In the Sylva Arboretum area, Untan, plant origin has a stomata number of 15 with stomata size of 14.1 μm, stomatal hole 8.03 μm and neighboring cells 14.7 μm. In the green open space area of the plant, there were ketapang plants had 35 stomata with a stomata size of 16.03 μm, a stomata hole of 8.03 and a neighboring cell of 6.57. the stomata structure shows that the leaves found in the arboretum region have large stomata while the outside of the general green open space has a small stomata. Different conditions of light and temperature greatly influence the variation in numbers on the size of the stomata, stomatal holes and neighboring cells. The farther the distance between plants and crowded places the more the size of the stomata decreases.
