Banksia spinulosa var. collina is a shrub that grows along the east coast of Australia, in Queensland and New South Wales. Commonly known as Hill Banksia or Golden Candlesticks, it is a taxonomic variety of B. spinulosa (Hairpin Banksia). It is a popular garden plant widely sold in nurseries.
As with the other varieties of B. spinulosa (Hairpin Banksia), B. spinulosa var. collina grows as a multi-stemmed lignotuberous shrub with flower spikes that are all golden or golden with red or purple styles. Its leaves are broader than those of B. spinulosa var. spinulosa, and usually but not always serrate. It can be distinguished from B. spinulosa var. cunninghamii by its lignotuber and resultant multi-stemmed habit.
B. spinulosa var. collina was first published as Banksia collina by Robert Brown in 1810, based on specimens he found among hills in the vicinity of the Hunter River, New South Wales in New South Wales in 1802. Brown did not give an explicit reason for the specific epithet "collina", but it is universally accepted that it is from the Latin collinus ("of hills"), in reference to the topography of the area in which he first found it. The species is in fact not restricted to hilly terrain, so the specific epithet is misleading. Brown apparently neglected to collect a specimen for the taxon, so a specimen collected by George Caley at Newcastle has since been declared a neotype.
It retained its specific rank in Brown's 1830 arrangement of Banksia, being placed in subgenus Banksia verae, the "True Banksias", because its inflorescence is a typical Banksia flower spike. It was placed immediately after B. cunninghamii (now B. spinulosa var. cunninghamii) and B. spinulosa, and before B. occidentalis (Red Swamp Banksia).Banksia verae was renamed Eubanksia by Stephan Endlicher in 1847.
