This species is closely allied to Sida ovate Forssk. from which it may be differentiated by its solitary and yellow flowers, long, glabrescent pedicels which are jointed near the top, and mericarp with raised reticulation on the redial surface. It resembles Sida pakistanica S.Abedin in its mericarp, but differs by small, subangular calyx not enclosing the fruit.
