Stem samples of G</em><em>.</em><em> versteegii were used from collections of the Agarwood Center Laboratory, Faculty of Mathematics and Natural Science, University </em><em>of </em><em>Mataram</em> <em>that </em><em>were </em><em>taken from Sumbawa Island. This research </em><em>used</em> <em>permanent slides</em><em> with </em><em>freehand</em><em> section and maceration methods. </em><em>O</em><em>bserv</em><em>ation</em> <em>d</em><em>ata </em><em>consisted</em> <em>of </em><em>cortex tissue</em><em>s</em><em>, xylem, pith</em><em>,</em><em> and Ca-Oxalate crystals. </em><em>The results showed that there were four provenances of G</em><em>.</em><em> versteegii on Sumbawa Island, namely provenance Pantai, Hajumee, Kayu</em><em>k</em><em> Pisak</em><em>,</em><em> and new provenance (Tartar provenance</em><em>)</em><em>. Comparison of anatomy between the stems of G. versteegii provenance Pantai with other provenances had differences in periderm thickness, </em><em>the pattern of </em><em>tissue sclerenchyma, interxylary phloem thickness, cortical parenchyma diameter, number of rows of wood parenchyma tissue,</em> <em>tracheid diameter, pith cell diameter, Ca-oxalate shape. </em><em>P</em><em>rovenance Hajumee with Tartar and </em><em>Kayuk pisak</em><em> differ</em><em>ed</em><em> in trachea length, trachea diameter, and the length of the tracheids, while between the provenances of Tartar and Kayuk pisak differ</em><em>ed</em><em> in the frequency of the trachea, the length of the fiber tracheids, the arrangement of the pith radius, and the location of the pith.</em></p&gt;}, number={1}, journal={Jurnal Ilmu Kehutanan}, author={Mulyaningsih, Tri and Muspiah, Aida and Sany, Zainul Muttaqin}, year={2022}, month={Mar.}, pages={84-100} }
