Foliage

Banksia vincentia is a shrub that grows in a small location in southern New South Wales. It belongs to the Banksia spinulosa species complex and has affinities to Banksia neoanglica , found several hundred kilometres to the north. [1]

Contents

B. vincentia was described by Marge Stimpson and Peter Weston in 2014, having been initially discovered in 2008. [1] Local nursery owner Jacki Koppman came across the plant and suspected it was a distinct species, sending material to the New South Wales Herbarium for assessment and identification. [2]

Description

Banksia vincentia has a semi-prostrate habit, growing as a squat, spreading shrub 30–75 cm high by 1–2 m wide, with branches growing horizontally from a lignotuber for 20–30 cm before veering upwards. [1] [3]

Leaves are either entire or have 1-6 marginal teeth or undulations in distil parts and grow to 12-47 mm long and 2-6.5 mm wide. They are narrowly oblong-obovate with leaf tips being rounded to truncate. Leaf margins are slightly recurved and densely covered in short hairs. The petiole of the leaves are 1-3.5 mm long and moderately to densely covered in hair. [3]

Conservation

Banksia vincentia is known from a single population of plants—14 at time of discovery and now down to 12 individual shrubs. [2] Some of the threats faced by the plant include: impact of road maintenance on highly restricted population, degradation of habitats from increasing urbanization, poor knowledge of the species' distribution and potential abundance, habitat invasion by weeds and invasive grasses, and the presence of Phytophthora cinnamomi which is suspected to have killed several individuals. [3]

Conservation has involved storing and germinating seed as well as cultivating new plants from cuttings at the Australian Botanic Gardens in Canberra, and Wollongong Botanic Gardens. Material has been sent to the Kew Royal Botanic Gardens in England as well. [2]

<i>Banksia spinulosa</i> Woody shrub in the family Proteaceae, native to eastern Australia

Banksia spinulosa, the hairpin banksia, is a species of woody shrub, of the genus Banksia in the family Proteaceae, native to eastern Australia. Widely distributed, it is found as an understorey plant in open dry forest or heathland from Victoria to northern Queensland, generally on sandstone though sometimes also clay soils. It generally grows as a small shrub to 2 metres (7 ft) in height, though can be a straggly tree to 6 metres (20 ft). It has long narrow leaves with inflorescences which can vary considerably in coloration; while the spikes are gold or less commonly yellowish, the emergent styles may be a wide range of colours – from black, purple, red, orange or yellow.

<i>Banksia marginata</i> Tree or woody shrub in the family Proteaceae found throughout much of southeastern Australia

Banksia marginata, commonly known as the silver banksia, is a species of tree or woody shrub in the plant genus Banksia found throughout much of southeastern Australia. It ranges from the Eyre Peninsula in South Australia to north of Armidale, New South Wales, and across Tasmania and the islands of Bass Strait. It grows in various habitats, including Eucalyptus forest, scrub, heathland and moorland. Banksia marginata varies widely in habit, ranging from a 20-centimetre (7.9 in) shrub to a 12-metre (40 ft) tree. The narrow leaves are linear and the yellow inflorescences occur from late summer to early winter. The flower spikes fade to brown and then grey and develop woody follicles bearing the winged seeds. Originally described by Antonio José Cavanilles in 1800, further collections of B. marginata were designated as several separate species by Robert Brown in 1810. However, all were reclassified as a single species by George Bentham in 1870. No distinct subspecies have been recognised by Banksia expert Alex George, who nonetheless concedes that further work is needed.

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

Banksia oblongifolia, commonly known as the fern-leaved, dwarf or rusty banksia, is a species in the plant genus Banksia. Found along the eastern coast of Australia from Wollongong, New South Wales in the south to Rockhampton, Queensland in the north, it generally grows in sandy soils in heath, open forest or swamp margins and wet areas. A many-stemmed shrub up to 3 m (9.8 ft) high, it has leathery serrated leaves and rusty-coloured new growth. The yellow flower spikes, known as inflorescences, most commonly appear in autumn and early winter. Up to 80 follicles, or seed pods, develop on the spikes after flowering. Banksia oblongifolia resprouts from its woody lignotuber after bushfires, and the seed pods open and release seed when burnt, the seed germinating and growing on burnt ground. Some plants grow between fires from seed shed spontaneously.

<i>Hibiscus heterophyllus</i> Species of tree

It is found mainly along the eastern edge of the Great Dividing Range.
