Callirhoë
Callirhoë leiocarpa
Species 9 (9 in the flora).
Several species of Callirhoë are gynodioecious; populations of C. alcaeoides, C. involucrata, and C. leiocarpa have individuals with either bisexual or functionally pistillate (that is, male-sterile) flowers. In these species the functionally pistillate flowers can be recognized by their reduced number of anther sacs, failure of these anther sacs to dehisce, stigmatic lobes often conspicuous at early anthesis, reduced petal size, and in C. alcaeoides shorter calyx lobe length. A few populations of C. pedata in Arkansas exhibit a corolla size dimorphism suggesting that this species too may be gynodioecious. Several species of Callirhoë are cultivated and may escape. All taxa of this genus occur within the flora area except C. involucrata var. tenuissima Palmer ex Baker f., which is wholly Mexican.

Callirhoë leiocarpa has been confused with C. pedata by some authors. It is cultivated occasionally.
