Abstract
<em>Citrus is one of the horticultural plants found in Indonesia and is in great demand. The diversity of oranges is very high as indicated by the number of Citrus members. North Sumatra is one of the province with high citrus productivity. Therefore, this study aims to identify the diversity of citrus plants based on their morphological characters in Nibung Hangus area, Batu Bara, North Sumatra. Data were collected by exploration method. Morphological identification is carried out to assess the morphological diversity of samples taken at the study site, including visual observations of the size, shape and color of plant organ parts. The organs observed included the stems, leaves and fruit of citrus plants. Morphological characterization using the guidelines in IPGRI and the book of Tjitrosoepomo (2002). The data analysis was carried out in a descriptive qualitative. The results showed that there were 5 types of citrus plants found in Nibung Hangus, namely Pamelo Plant (Citrus maxima), Lime Plant (Citrus aurantifolia), Tangerine Plant (Citrus reticulata blanco), Kaffir Lime Plant (Citrus hystrix), and Sunkist Citrus Crop (Citrus sinensis).</em>

Karakterisasi Morfologi Daun dan Anatomi Stomata pada Beberapa Spesies Tanaman Jeruk (Citrus sp)
Summary
Penelitian ini dilaksanakan pada Kecamatan Nibung Hangus, Kabupaten Batu Bara, Sumatera Utara pada Desember hingga Januari 2021. Adapun alat yang digunakan yaitu: pisau, double tip, penggaris, kamera, alat tulis, dan buku panduan yang relevan. Penelitian ini adalah tanaman jeruk (Citrus sp.) yang terdapat dalam area Nibung Hangus. Pengambilan data dilakukan dengan metode eksplorasi secara langsung ke lokasi penelitian. Identifikasi morfologi dilakukan untuk mendalami keragaman morfologi dari sampel yang diambil di lokasi tersebut, dengan mengamati ukuran, bentuk, dan warna bagian-bagian organ tanaman. Organ yang diamati mencakup batang, daun, dan buah dari tanaman jeruk. Karakterisasi morfologi menggunakan pedoman pada International Plant Genetic Resources Institute (IPGRI, 1999) dan buku referensi Tjitrosoepomo (2002).
