Syzygium cumini (L.) Skeels (Madan) is widely distributed in South Asian countries, including Sri Lanka, where it was naturally found. There were only few studies reported on S. cumini for its values and other benefits in Sri Lanka. This study focuses on morphological characterization and the diversity of S. cumini trees in seven locations of Sri Lanka. Data were collected on different morphological traits. Leaf, flower and fruit morphology showed significant differences among locations. Further, trees from Batticaloa region showed different morphology, which would potentially open a different avenue for further study to trace different cultivars across the country. Results of the diversity index and multivariate analyses indicated high diversity in morphology and antioxidant capacity of trees. The variables such as leaf area, inter-nodal length, petiole length, anther length, filament length, fruit size and pericarp thickness could be suitable candidates to investigate the morphological variation of S. cumini any further. Antioxidant capacity studies also showed significant differences among locations and trees. Fruit hue angle was positively correlated to antioxidant capacities. Finding of this study concluded that the wide distribution of S. cumini trees throughout Sri Lanka in different geographical locations showed high diversity in leaf, flower and fruit morphology together with antioxidant capacity.

Syzygium cumini  (L.) Skeels (Madan) 广泛分布于南亚国家，包括自然发现的斯里兰卡。在斯里兰卡，关于小茴香的价值和其他好处的研究报告很少。本研究侧重于小茴香的形态特征和多样性斯里兰卡七个地方的树木。收集关于不同形态特征的数据。叶、花和果实形态在不同地点表现出显着差异。此外，来自 Batticaloa 地区的树木表现出不同的形态，这可能为进一步研究开辟不同的途径，以追踪全国不同的栽培品种。多样性指数和多变量分析的结果表明树木的形态和抗氧化能力具有高度的多样性。叶面积、节间长度、叶柄长度、花药长度、花丝长度、果实大小和果皮厚度等变量可作为研究小茴香形态变异的合适候选者任何进一步。抗氧化能力研究还显示地点和树木之间存在显着差异。果实色调角度与抗氧化能力呈正相关。这项研究的结果得出结论，斯里兰卡不同地理位置的小茴香树的广泛分布在叶、花和果实的形态以及抗氧化能力方面表现出高度的多样性。
