Banksia ser. Dryandra is a series of 94 species of shrub to small tree in the plant genus Banksia . It was considered a separate genus named Dryandra until early 2007, when it was merged into Banksia on the basis of extensive molecular and morphological evidence that Banksia was paraphyletic with respect to Dryandra.

Taxonomy

The dryandras were named in honour of Swedish botanist Jonas C. Dryander. The first specimens of a Dryandra were collected by Archibald Menzies, surgeon and naturalist to the Vancouver Expedition. At the request of Joseph Banks, Menzies collected natural history specimens wherever possible during the voyage. During September and October 1791, while the expedition were anchored at King George Sound, he collected numerous plant specimens, including the first specimens of B. sessilis (Parrotbush) and B. pellaeifolia . Upon Menzies' return to England, he turned his specimens over to Banks; as with most other specimens in Banks' library, they remained undescribed for many years. [1]

Further specimens were collected in late 1792 by Jacques Labillardière, one of five naturalists in Bruni d'Entrecasteaux's expedition in search of the lost expedition of Jean-François de La Pérouse. While ashore west of Esperance Bay between 11 and 18 December, Labillardière collected the first specimens of B. nivea (Honeypot Dryandra). [1]

Description

They are arguably among the most attractive and showy of all members of Proteaceae.

Banksia ser. Dryandra species are used as food plants by the larvae of some Lepidoptera species, including the Dryandra moth.

Endemic to Western Australia, Dryandra occurs virtually throughout the South West Botanic Province, and also, to a much lesser degree, in southwest parts of the Eremaean Province.

Cultivation

The species are found only in the southwestern corner of Western Australia. They have never been popular among gardeners among the rest of Australia due to their dislike of the humid and subtropical conditions which dominate the east coast.[ citation needed ]

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 sessilis</i> Species of plant of Western Australia

Banksia sessilis, commonly known as parrot bush, is a species of shrub or tree in the plant genus Banksia of the family Proteaceae. It had been known as Dryandra sessilis until 2007, when the genus Dryandra was sunk into Banksia. The Noongar peoples know the plant as budjan or butyak. Widespread throughout southwest Western Australia, it is found on sandy soils over laterite or limestone, often as an understorey plant in open forest, woodland or shrubland. Encountered as a shrub or small tree up to 6 m (20 ft) in height, it has prickly dark green leaves and dome-shaped cream-yellow flowerheads. Flowering from winter through to late spring, it provides a key source of food—both the nectar and the insects it attracts—for honeyeaters in the cooler months, and species diversity is reduced in areas where there is little or no parrot bush occurring. Several species of honeyeater, some species of native bee, and the European honey bee seek out and consume the nectar, while the long-billed black cockatoo and Australian ringneck eat the seed. The life cycle of Banksia sessilis is adapted to regular bushfires. Killed by fire and regenerating by seed afterwards, each shrub generally produces many flowerheads and a massive amount of seed. It can recolonise disturbed areas, and may grow in thickets.

<i>Banksia acanthopoda</i> Species of shrub in Western Australia

Banksia acanthopoda is a species of shrub in the family Proteaceae. It grows as a small spreading shrub to 2 m high and has prickly leaves and yellow composite flower heads, called inflorescences, composed of 50 to 60 individual yellow flowers. Flowering takes place in the southern hemisphere winter. Endemic to Western Australia, it occurs only in a few populations in the vicinities of Woodanilling, Katanning and Darkan. Because of its rarity, it is classed as "Priority Two" conservation flora by Western Australia's Department of Environment and Conservation.
