Banksia sect. Oncostylis is one of four sections of subgenus Banksia subg. Banksia. It contains those Banksia species with hooked pistils. All of the species in Oncostylis also exhibit a top-down sequence of flower anthesis, except for Banksia nutans which is bottom-up.

Contents

Banksia sect. Oncostylis is further divided into four series, primarily on the overall shape of the inflorescence:

All Oncostylis species are endemic to southwest Western Australia, except for two members of series Spicigerae, Banksia ericifolia (Heath-leaved Banksia) and Banksia spinulosa (Hairpin Banksia), which are endemic to the east coast of Australia.

<i>Banksia dryandroides</i> Species of shrub in the family Proteaceae from the south coast of Western Australia

Banksia dryandroides, the dryandra-leaved banksia, is a species of small shrub in the plant genus Banksia. The Noongar peoples know the tree as manyat. It occurs in shrubland, woodland and kwongan on the south coast of Western Australia between Narrikup and Beaufort Inlet. The species is placed alone in series B. ser. Dryandroideae.

<i>Banksia grossa</i> Shrub in the family Proteaceae endemic to Southwest Australia

Banksia grossa is a species of shrub in the family Proteaceae and is endemic to Southwest Australia. It is one of fourteen species of banksia of the series Abietinae, all of which bear predominantly cylindrical or oval inflorescences. Collected in 1965, it was first formally described in 1981 by Alex George. Its thick leaves and large seeds distinguish it from other members of the Abietinae, and are the basis of its species name.

<i>Banksia lindleyana</i> Species of shrub in the family Proteaceae from Western Australia

Banksia lindleyana, commonly known as the porcupine banksia, is a species of woody shrub in the genus Banksia of the family Proteaceae. It generally grows as a small shrub to 1 m (3 ft) high with long narrow serrated leaves, and bright yellow oval or round inflorescences. Flowering occurs in late summer, after which time the flower spikes age and turn to brown and then grey, and develop up to 70 follicles. It occurs in the vicinity of Kalbarri, Western Australia. Found on sandy soils, the plant serves as a pollinator for a variety of bird and animal species.

<i>Banksia nutans</i> Species of shrub in the family Proteaceae native to the south coast of Western Australia

Banksia nutans, commonly known as nodding banksia, is a species of shrub native to the south coast of Western Australia in the genus Banksia. Growing to a metre (3 ft) tall, it has pale blue-green fine-leaved foliage and unusual purple-brown inflorescences which hang upside down rather than grow upright like most other banksias.

<i>Banksia repens</i> Species of shrub in the family Proteaceae native to Western Australia

Banksia repens, the creeping banksia, is a species of shrub in the plant genus Banksia. It occurs on the south coast of Western Australia from D'Entrecasteaux National Park in the west to Mount Ragged in the east.

<i>Banksia seminuda</i> Species of tree in the family Proteaceae found in south west Western Australia

Banksia seminuda, commonly known as the river banksia, is a tree in the plant genus Banksia. It is found in south west Western Australia from Dwellingup (32°42′ S) to the Broke Inlet east of Denmark (34°57′ S). It is often mistaken for, and was originally considered a subspecies of, the Banksia littoralis. Stephen Hopper described the subspecies remanens as a short-leaved shrubby form found in the coastal sands below granite outcrops in the Walpole-Nornalup National Park, however George does not feel this form warrants taxonomic recognition as it lies within the normal variability of the species and there was no clear distinction between it and the other populations of B. seminuda.

<i>Banksia sphaerocarpa</i> Shrub or tree in the family Proteaceae widely distributed across the southwest of Western Australia

Banksia sphaerocarpa, commonly known as the fox banksia or round-fruit banksia, is a species of shrub or tree in the plant genus Banksia. It is generally encountered as a 1–2 m (3.3–6.6 ft) high shrub, and is usually smaller in the north of its range. This species has narrow green leaves, and brownish, orange or yellow round flower spikes which may be seen from January to July. It is widely distributed across the southwest of Western Australia, growing exclusively in sandy soils. It is usually the dominant plant in scrubland or low woodland. It is pollinated by, and is a food source for, birds, mammals, and insects.

<i>Banksia verticillata</i> A shrub of southwest Western Australia

Banksia verticillata, commonly known as granite banksia or Albany banksia, is a species of shrub or (rarely) tree of the genus Banksia in the family Proteaceae. It is native to the southwest of Western Australia and can reach up to 3 m (10 ft) in height. It can grow taller to 5 m (16 ft) in sheltered areas, and much smaller in more exposed areas. This species has elliptic green leaves and large, bright golden yellow inflorescences or flower spikes, appearing in summer and autumn. The New Holland honeyeater is the most prominent pollinator, although several other species of honeyeater, as well as bees, visit the flower spikes.

<i>Banksia violacea</i> Species of plant

Banksia violacea, commonly known as violet banksia, is a species of shrub or tree in the plant genus Banksia. It generally grows as a small shrub to 1.5 m (5 ft) high with fine narrow leaves, and is best known for its unusually coloured dark purple-violet inflorescences. The colour of the inflorescences, short leaves, and flattened follicles which are sticky when young, help identify this species from others in the field. It is found in low shrubland in southern regions of Western Australia from Esperance in the east to Narrogin in the west, growing exclusively in sandy soils.

<i>Banksia <span style="font-style:normal;">ser.</span> Dryandroideae</i> Series of Banksia

Banksia ser. Dryandroideae is a taxonomic series in the plant genus Banksia. First published by Carl Meissner in 1856, the name has had two circumscriptions. As presently circumscribed it is monotypic, containing only B. dryandroides.

<i>Banksia <span style="font-style:normal;">ser.</span> Spicigerae</i> Taxonomic series in the family Proteaceae

Banksia ser. Spicigerae is a taxonomic series in the genus Banksia. It consists of the seven species in section Oncostylis that have cylindrical inflorescences. These range in form from small shrubs to tall trees. The leaves grow in either an alternate or whorled pattern, with various shape forms. The Spicigerae inflorescence is held erect, subtended by a whorl of branchlets, and retains a regular pattern until anthesis. The perianth limb is horizontal until anthesis, at which point the perianth opens from underneath. The pollen-presenter is ovoid or conical. The seed wings are not notched.
