The genus is one of the largest in the family. They are most easily distinguished from other genera in the family by their three-lobed or spear-shaped antherodes (i.e. non-functional anthers).[3] Also, along with the closely related genus Anthericopsis, it is the only genus with staminodes (i.e. non-functional stamens) opposite the petals.[4]

Murdannia are found in tropical regions across the globe with extensions into warm temperate areas.[1] Typically, Murdannia species are found in open areas in mesic soils. However, some are semi-aquatic, and a limited few are found in closed forest situations. Three species are naturalized in the United States (Murdannia keisak, M. nudiflora and M. spirata).[5][6][7]

The genus is named in honor of Murdan Ali, a plant collector who worked for John Forbes Royle and maintained the herbarium at Saharunpore, India.[6][8] He was a munshi who took a keen interest in natural history and under the training of Falconer, Royle and Edgeworth had become a proficient botanist who compiled a vernacular flora of northern India and the Himalayas which was however never published.[9]
