Material with the margin of the capsule ± smooth (almost no denticulations) has been separated as Salomonia cantoniensis var. edentula, but as the degree of denticulation in this species is variable and as S. cantoniensis var. edentula is in all other aspects identical to S. cantoniensis, the variety is not here recognized.
