This study aimed to determine the diversity and clustering of Faloak (Sterculia quadrifida R.Br) from Kupang District based on morphological and anatomical characters. This research used descriptive qualitative and quantitative methods. To show the clustering relationship, we used the UPGMA method similarity by the Nei Li coefficient through the MVSP software program version 3.2. Results showed that there was a relationship of Faloak plants from both locations in Kupang district forming 4 groups including Group I (Kupang Barat populations); Group II (Taebenu 3 pupulation), Group III (Kupang Barat 3 and Taebenu 2 populations) and Group IV (Kupang Barat 2 and Taebenu 1 populations). The anatomical characters showed a clear similarity on the epidermal cell, thick inner wall, guard cell, and stomatal pore. The type of trichome on the leaves of Faloak plants from these two sub-districts also showing a similarity, namely non-glandular trichome type.

This study aims to determine the morphological and anatomical characteristic kinship of faloak plant (Sterculia quadrifida R.Br) growing in Kupang Regency as learning source for morphology and anatomy of plant course based on local natural resources. The study was conducted at the Laboratory of Biology Education Study Program, Kupang Muhammadiyah University from March to May 2019. This study used a qualitative descriptive approach with cluster analysis method. To see the kinship of the plant, this study used UPGMA method of Nei and Li's coefficient similarity through the MVSP software program version 3.2. The results of this study show that faloacic kinship from the three locations in Kupang Regency had a value of 77%. Meanwhile, anatomical characteristics show that the highest stomata density value was 5.6 stomata/µm and the lowest stomata density value was 2.9 stomata/µm.
