Banksia montana, commonly known as the Stirling Range dryandra, [2] is a species of shrub that is endemic to the Stirling Range in Western Australia. It has hairy stems, linear pinnatisect leaves with twisted, triangular lobes, yellow flowers in heads of about sixty and reddish-brown follicles.

Description

Banksia montana grows as a shrub to 2.5 m (8 ft 2 in) high but does not form a lignotuber. Its stems are covered in short, rust-coloured hairs. The leaves linear, pinnatisect, 80–250 mm (3.1–9.8 in) long and 6–11 mm (0.24–0.43 in) wide with between thirty-five and sixty lobes on each side. The lobes are twisted and curved, so that the undersurface faces the apex of the leaf. The flowers are yellow and arranged in head of between fifty and sixty on a branchlet one or two years old with linear to lance-shaped involucral bracts about 15 mm (0.59 in) long at the base of the head. The perianth is 17–19 mm (0.67–0.75 in) long and hairy, the pistil 18–21 mm (0.71–0.83 in) long and curved. Flowering occurs from December or January to February and the follicles are dark reddish-brown, egg-shaped and 9–11 mm (0.35–0.43 in) long and sparsely hairy. The follicles remain on the plant for up to four years before disintegrating. [2] [3] [4] [5]

Taxonomy

The type specimen was collected by Ken Newbey from Bluff Knoll in the Stirling Range on 14 January 1966. Western Australian State botanist Charles Austin Gardner coined the name Dryandra montana but did not publish it. The species was first formally described as D. montana in 1996 by Alex George in the journal Nuytsia . [5] [6] In 2007, Austin Mast and Kevin Thiele transferred all the dryandras to the genus Banksia and this species became Banksia montana. [7] [8] The specific epithet (montana) is from the Latin word montanus meaning "pertaining to mountains" referring to the habitat of this banksia. [9]

Distribution and habitat

Banksia montana is found only on the upper slopes of Bluff Knoll above 900 m (3000 ft) altitude, on sandstone, metamorphosed sandstone or siltstone. It is a component of the endangered Eastern Stirling Range Montane Heath and Thicket Threatened Ecological Community. Four populations containing a total of 45 adult and 16 juvenile plants were known in 2004. [2]

Ecology

Stirling Range dryandra is killed by bushfire and regenerates from seed. Taking up to nine years to flower and fruit from seed, it is thought to require bushfires at intervals of 18 years for best recovery. However, two fires in quick succession in its native habitat killed many plants with little recruitment. The species is also highly sensitive to dieback ( Phytophthora cinnamomi ), which has infested three of four extant populations. [2]

A species of mealybug, Pseudococcus markharveyi, was discovered on its leaves, and is possibly only associated with this species, making it likely to be endangered as well. [10]

Conservation status

Banksia montana is classified as "endangered" under the Australian Government Environment Protection and Biodiversity Conservation Act 1999 [11] and a recovery plan (for Dryandra montana) has been prepared. [2] It is also classified as "Threatened Flora (Declared Rare Flora — Extant)" by the Department of Environment and Conservation (Western Australia). The main threats to the species are habitat loss due to Phytophthora cinnamomi infestation and inappropriate fire regimes. [3] [2]

Use in horticulture

Stirling Range dryandra has been grown successfully in containers at Kings Park in Perth and at the Banksia Farm at Mount Barker. [12]

<i>Banksia aculeata</i> Shrub of the family Proteaceae native to the southwest of Western Australia.

Banksia aculeata, commonly known as prickly banksia, is a species of plant of the family Proteaceae native to the Stirling Range in the southwest of Western Australia. A shrub up to 2 m (7 ft) tall, it has dense foliage and leaves with very prickly serrated margins. Its unusual pinkish, pendent (hanging) flower spikes, known as inflorescences, are generally hidden in the foliage and appear during the early summer. Although it was collected by the naturalist James Drummond in the 1840s, Banksia aculeata was not formally described until 1981, by Alex George in his monograph of the genus.

<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.

The only known population is in danger of extinction from dieback disease.
