Discussion

In recent floras Mirabilis laevis var. crassifolia has been treated as M. californica or M. laevis. The California specimen of M. tenuiloba var. polyphylla (Standley) J. F. Macbride cited by Macbride (1918) [M. polyphylla (Standley) Standley] is considered to be M. laevis var. crassifolia. It has fruiting involucres at the upper range of its length, similar to some plants from the Channel Islands. In Baja California, indigenous peoples have used the plants of var. crassifolia to alleviate stomach ailments.
