Abstract
Examination of the flowers of Elingamita johnsonii confirms that the specie s is functionally dioecious. Female flowers have a well-developed ovary, ca pitate stigma, and anthers which produce pollen with occluded apertures. Ma le flowers produce abundant aperturate pollen and have a rudimentary ovary that lacks a normally developed stigma and placenta. The sizes of the flora l parts differ in each sex, with the female having smaller sepals, petals, and anthers, and shorter filaments. Male plants have larger inflorescences, more flowers per inflorescence, and more pollen grains per anther.
