There are three subspecies:[2][1]
- Boronia barkeriana subsp. angustifolia Duretto has egg-shaped sepals more than Шаблон:Convert wide and leaves Шаблон:Convert long and Шаблон:Convert wide
- Boronia barkeriana F.Muell.subsp. barkeriana has triangular sepals Шаблон:Convert wide and leaves Шаблон:Convert long and Шаблон:Convert wide
- Boronia barkeriana subsp. gymnopetala Duretto has triangular sepals Шаблон:Convert wide and leaves Шаблон:Convert long and Шаблон:Convert wide
Distribution and habitat
This boronia grows in moist places on sandstone.
- Subspecies angustifolia mainly grows in Morton and Budderoo National Parks [2][6]
- Subspecies barkeriana grows on the coast and ranges near Braidwood.[2][7]
