15 subspecies recognized currently. The main features used by Randell (1989) to distinguish the 5 Victorian subspecies (petiole length, width and cross-sectional shape and leaflet number, length, width, cross-sectional shape and indumentum) are extremely variable and plants of intermediate morphology commonly occur.
See note under the profile for Senna regarding the complex breeding systems that, at least partially, explain the often confounding array of variation observed in the field.
