Discussion:The flve prominent, setaceous calyx-lobes and long setaceous, persistent stipules present in this species are characters mostly at variance with other members of the genus Alibertia. The species appears to be most closely related to A. triflora (A. Rich.) K. Schum., in which the calyx teeth are somewhat conspicuous and the stipules are elongated-triangular.
