Menkea
Annual herbs, prostrate or erect, glabrous (in Victoria). Leaves in basal rosette and cauline, entire, lobed or pinnately dissected. Inflorescence a raceme. Sepals spreading, sometimes hooded or saccate; petals clawed, white to pink or mauve (or yellow outside Victoria); stamens 6. Fruit c. 1–2 times as long as broad, dehiscent; style short with depressed-capitate stigma; septum reduced to absent; seeds in 2 rows, numerous.
6 species, endemic to Australia.
Species of Menkea have small, compressed or inflated fruits in which the septum is reduced to a narrow rim or completely absent, and the seeds are in 2 rows and numerous. The outer rim of the fruit, sometimes with a inner membranous flange (the septum), persists in old infructescences. Hornungia has fruits superficially similar to those of Menkea but the septum is fully developed across the narrowest diameter.
