Discussion

Malachra capitata is introduced in Malesia according to J. van Borssum Waalkes (1966), who synonymized M. capitata and M. alceifolia Jacquin. The Louisiana records are thought to represent adventive or introduced populations. Those in southern Florida and Texas are accepted as native populations.
