Closely related to V. arcuata but readily distinguished from typical forms of that species by its subcoriaceous, strongly crenate, ovate leaves and its long-fimbriate stipules. Some forms of V. arcuata, particularly in drier habitats, approach V. javanica in these characters but the stigma has the rounded separate lobes of V. arcuata and not the posteriorally fused, flatter margin of V. javanica. There is a superficial resemblance to some forms of V. pilosa but in that species the style is scarcely clavate and the stigma is emarginate.
