Calamus is one of the largest genera in the Arecaceae family, with 416 species classified under the subtribe Calaminae and the tribe Calameae. This genus is widely distributed across tropical and subtropical regions, including in Africa, Asia, and the southwest Pacific. Despite its extensive distribution, some species are known to be regionally endemic, with Calamus reinwardtii Mart., in particular, being found only in Java. The primary aim of this study was to confirm the presence of C. reinwardtii Mart.inBanyumas, Central Java, and to examine potential morphological variations between populations from those grown naturally in Western and Eastern Java. Through an analysis of specimens from Herbarium Bogoriense (BO), this study provides new insights into the distribution and morphological characteristics of C. reinwardtii Mart. Our findings contribute to a better understanding of the species distribution within Java and adding to the knowledge of the genus Calamus in the region.
