Within Boronia Sm. section Valvatae (Benth.) Engl. the B. grandisepala F.Muell. species group is characterised by a calyx as large or larger than the corolla, simple leaves, and multiangular stellate hairs. The group includes B. grandisepala, a related complex of species, and six newly described species: B. amplectens Duretto, B. quadrilata Duretto, B. suberosa Duretto, B. verecunda Duretto, B. viridiflora Duretto and B. xanthastrum Duretto.

Four taxa were recognised in the complex and three, B. grandi..
