Kepel (Stelechocarpus burahol) is a distinctive flora of the Special Region of Yogyakarta, which is currently difficult to find and scarce. Which means that conservation should be carried out, otherwise it will become extinct. The purpose of this study was to determine the morphological characteristics and to know the kepel plant kinship in Sleman Regency. The study was conducted by survey method. The selection of sample trees is done by purposive sampling, with the criteria that the plants have ever borne fruit or they are bearing fruit and grow healthy. Observations which were carried out included position, symmetry, length, shape, width, diameter, weight, thickness, skin type, skin color, maturity level of fruit, weight, length, width, thickness, diameter, number of seeds, color, thickness, texture, and taste of fruit flesh. In 19 plants, distribution maps were made, identifying morphological characters, and analyzed using the NTSYS (Numerical Taxonomic and Multivariate System) programme. The results showed that there was a diversity of Kepel morphology in Sleman, namely shape, length, width, thickness, diameter, weight, maturity level of fruit, thickness, color, taste, texture of fruit flesh, number of seeds, weight, length, width, thickness, and diameter of seeds. The results of the analysis with the kinship analysis program showed that there were six main clusters with a similarity coefficient of 0.425. Which is cluster 1 (5 plants), cluster 2 (4 plants), cluster 3 (1 plant), cluster 4 (5 plants), cluster 5 (1 plant) ), and cluster 6 (3 plants).
