<![CDATA[Coleus Lour. is an Old-World genus widely cultivated as ornamental and medicinal plants, with seven species previously documented from Java. However, the regional flora continues to change due to ongoing horticultural introductions, and recently introduced cultivated taxa remain under-documented. This study aims to document the occurrence of an additional ornamental Coleus species in Java and to clarify its taxonomic and floristic significance. Field observations and specimen collections were conducted in West Java, and taxonomic identification was based on morphological examination and comparison with relevant literature. As a result, Coleus prostratus (Gürke) A.J.Paton is recorded here for the first time from Java, where it occurs exclusively in cultivated settings as a hanging ornamental plant. The species is readily distinguishable from other Coleus taxa in Java by its prostrate habit, small fleshy leaves, and characteristic vegetative morphology. This record increases the documented diversity of Coleus in Java and highlights the importance of documenting cultivated ornamental plants as part of contemporary floristic inventories, particularly in relation to future assessments of naturalization and biodiversity change. ]]>
