Diplarrhena moraea is a tufted perennial in the iris family notable for having only two functional stamens rather than the usual three found in Iridaceae. It produces basal, linear leaves that remain present throughout the year and an erect stem bearing single flowers from a green terminal spathe. The flowers are iris-like and zygomorphic, each with six white tepals and a style with two thread-like branches. Plants grow from short rhizomes and form discrete clumps that can be increased by division.
