Kepel is a typical plant of the Daerah Istimewa Yogyakarta. Kepel to date have not been widely cultivated. Kepel fruit is also rarely found due to its small population. This study aims to obtain information about the diversity of Kepel morphology in Kotamadya Yogyakarta. Research has been conducted in Kotamadya Yogyakarta from October 2018 to January 2019. The study was conducted using a survey method with purposive sampling technique. Plants that are used as samples are plants that have never been fruitful. Observations made were in the form of sample plant data and sample plant environmental data. Plant data regarding the morphological characteristics of the plants obtained directly from the sample plants, while the sample environmental data of the plants needed were the study location, soil type and soil pH, light intensity, temperature and humidity. Data from plant morphology observations are presented in the form of scoring, then an analysis is performed to assess the similarity matrix using the SIMQUAL (Similarity for Qualitative Data) procedure. Grouping of matrix data (cluster analysis) and making dendograms are done by the Unweigthed Pair-Group Method Arithmetic Average (UPGMA) method using Numerical Taxonomic and Multivariate System (NTSYS) version 2.02i. The results showed similarities in the morphology of the canopy shape and leaf edge shape, while crown diameter, stem circumference, number of branches, stem color, number of nodes, blade shape, leaf base, leaf tip, leaf color, leaf length, leaf width, and leaf width. long stem has a difference. There are three kepel clusters in Kotamadya Yogyakarta with a similarity coefficient value of 0.54, namely cluster I: 6 plants (13%), cluster II: 23 plants (50%), and cluster III: 17 plants (37%), and there are 9 pairs of plants that are closely related to the similarity coefficient value 0.91.
