Asystasia neesiana is sometimes treated in Asystasiella Lindau, a genus of two species with spheroidal, 4- or 5-porate, and spinulate (vs. prolate-spheroidal to subprolate, 3-colporate, and reticulate) pollen (see K. Ensermu et al., Kew Bull. 47: 669-675. 1992). The generic position of Asystasia neesiana s.l. and some of its relatives has yet to be thoroughly investigated.
This species is used medicinally.
