The zygomorphic flowers of Impatiens are protandric (male becoming female with age). The calyx consists of five free sepals, of which one pair is often strongly reduced. The non-paired sepal forms a flower spur-producing nectar. In a group of species from Madagascar, the spur is completely lacking, but they still have three sepals.
