Grevillea milleriana is a flowering plant in the family Proteaceae native to a restricted distribution in the Maddens Plains area in New South Wales, Australia. It is currently only known from the holotype specimen.
Description.
"Grevillea milleriana" is a low, spreading, sub-prostrate shrub which typically grows up to high and wide, with the lowest branches trailing along the ground. The leaves are long and wide and are either lobed or entire with up to 8 broadly triangular lobes. The upper surface of the leaves is glabrous or nearly so and the lower surface of the leaves is silky hairy. The flowers are arranged in groups near the ends of branches, long and about wide on a peduncle long, each flower on a pedicel long. The perianth is long, pink outside and purplish-pink inside with a brown, limb long. The style is glabrous and the pollen-presenter is long and wide.
Similar species.
"Grevillea milleriana" is closely related to "G. barklyana", "G. macleayana" and "G. gilmourii," another species described in the same year. It can be distinguished from its relatives by its low, spreading habit, its longer pedicels () long and shorter anthers long.
Taxonomy.
"Grevillea milleriana" was first formally described by Peter M. Olde in the journal "Telopea" from specimens collected near Maddens Plains in 2021. The specific epithet ("milleriana") honours the discoverers of the species, R. T. Miller and Janice Miller.
The holotype was previously misidentified as a disjunct population of "G. caleyi", a species which only occurs within the Terrey Hills region north of Sydney.
