Banksia Rosserae
''Banksia rosserae'' is a recently described species of ''Banksia''. Endemic to inland Western Australia, it is the only ''Banksia'' species to occur solely within the arid zone. Description ''B. rosserae'' grows as a multi-stemmed shrub high, and wide. The trunks are from in diameter. Unusually for ''Banksia'' species, the grey bark is papery and flaky. The leaves are dark green, long and wide, with serrated margins. Flowers are yellow and occur in ''Banksias distinctive flower spikes; these are approximately spherical, with a diameter of about . The "cones" have a hairy appearance due to the retention of old flower parts. They typically contain from twelve to twenty follicles, most of which do not open until stimulated to do so by fire. Taxonomy Taxonomic history Reports of who first discovered ''B. rosserae'' are somewhat contradictory. Peter Olde and Neil Marriott acknowledge Ann Pilkington of Kirkalocka, "who discovered ''Banksia rosserae'' and who drew ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia
''Banksia'' is a genus of around 170 species in the plant family Proteaceae. These Australian wildflowers and popular garden plants are easily recognised by their characteristic flower spikes, and fruiting "cones" and heads. ''Banksias'' range in size from prostrate woody shrubs to trees up to 30 metres (100 ft) tall. They are found in a wide variety of landscapes: sclerophyll forest, (occasionally) rainforest, shrubland, and some more arid landscapes, though not in Australia's deserts. Heavy producers of nectar, ''banksias'' are a vital part of the food chain in the Australian bush. They are an important food source for nectarivorous animals, including birds, bats, rats, possums, stingless bees and a host of invertebrates. Further, they are of economic importance to Australia's nursery and cut flower industries. However, these plants are threatened by a number of processes including land clearing, frequent burning and disease, and a number of species are rare and endangered. ...

Cyclone Glenda
Severe Tropical Cyclone Glenda was among the strongest tropical cyclones to threaten Western Australia, though it weakened considerably before landfall and moved ashore in a lightly populated region. It began as a tropical low on 15 March in the Gulf of Carpentaria. The precursor disturbance drifted over Top End and later across the northeastern portion of Western Australia, and after emerging into the Indian Ocean it strengthened into a tropical storm. Aided by favourable environmental conditions, Glenda rapidly intensified to reach Category 5 status on the Australian cyclone scale, and with a peak intensity of 910 mbar it was among the strongest cyclones on record within the Australia region. On 30 March it moved ashore near Onslow as a Category 3 cyclone, and the next day it degenerated into a remnant tropical low over land. The precursor disturbance produced heavy rainfall in the Kimberley region of Western Australia, causing record flooding and some road da ...

Banksia Attenuata
''Banksia attenuata'', commonly known as the candlestick banksia, slender banksia, or biara to the Noongar people, is a species of plant in the family Proteaceae. Commonly a tree, it reaches high, but it is often a shrub in drier areas high. It has long, narrow, serrated leaves and bright yellow inflorescences, or flower spikes, held above the foliage, which appear in spring and summer. The flower spikes age to grey and swell with the development of the woody follicle (fruit), follicles. The candlestick banksia is found across much of the Southwest Australia, southwest of Western Australia, from north of Kalbarri National Park down to Cape Leeuwin and across to Fitzgerald River National Park. English botanist John Lindley had named material collected by Australian botanist James Drummond (botanist), James Drummond ''Banksia cylindrostachya'' in 1840, but this proved to be the same as the species named ''Banksia attenuata'' by Scottish botanist Robert Brown (botanist, born 1773) ...

Banksia Pilostylis
''Banksia pilostylis'' is a species of shrub that is endemic to the south-west of Western Australia. It has hard, fissured bark, narrow wedge-shaped, serrated leaves, pale yellow flowers in cylindrical spikes and elliptical follicles that open when heated in a bushfire. Description ''Banksia pilostylis'' is a shrub that typically grows to a height of and has hard, fissured bark but does not form a lignotuber. The leaves are serrated, narrow wedge-shaped, long and wide on a petiole long. The flowers are pale yellow and closely packed in a cylindrical spike long and wide with hairy involucral bracts long at the base of the spike. The perianth is long and the pistil long and curved. Flowering occurs from October to January and up to twenty-five elliptical follicles long and wide, surrounded by the remains of the flowers, develop in each spike. The follicles usually remain closed until the plant is killed in a bushfire. Taxonomy and naming ''Banksia pilostylis'' was ...

Banksia Epica
''Banksia epica'' is a shrub that grows on the south coast of Western Australia. A spreading bush with wedge-shaped serrated leaves and large creamy-yellow flower spikes, it grows up to 3½ metres (11½ ft) high. It is known only from two isolated populations in the remote southeast of the state, near the western edge of the Great Australian Bight. Both populations occur among coastal heath on cliff-top dunes of siliceous sand. One of the most recently described ''Banksia'' species, it was probably seen by Edward John Eyre in 1841, but was not collected until 1973, and was only recognised as a distinct species in 1988. There has been very little research on the species since then, so knowledge of its ecology and cultivation potential is limited. It is placed in ''Banksia'' ser. ''Cyrtostylis'', alongside its close relative, the well-known and widely cultivated '' B. media'' (southern plains banksia). Description ''Banksia epica'' grows as a spreading bushy sh ...

Banksia Praemorsa
''Banksia praemorsa'', commonly known as the cut-leaf banksia, is a species of shrub or tree in the plant genus ''Banksia''. It occurs in a few isolated populations on the south coast of Western Australia between Albany and Cape Riche. Description ''Banksia praemorsa'' grows as a shrub to with a relatively thick sturdy trunk that branches quite close to the ground. Occasionally specimens can be up to with a trunk diameter of . The bark is rough and flaky. Flowering occurs from August to November; the flower spikes arise from the ends of small lateral branches and thus, despite being terminal, are obscured by foliage. Up to high, they are composed of hundreds of individual flowers growing out of a vertical woody spike. Taxonomy English plantsman and botanical artist Henry Cranke Andrews described this species from a cultivated specimen in the conservatory of the Clapham Collection in July 1802. A specimen that flowered at Kew Gardens the same year was selected as the neotype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Media
''Banksia media'', the southern plains banksia or golden stalk banksia, is a species of flowering plant in the family Proteaceae. An evergreen shrub, it occurs on the south coast of Western Australia between Albany and Israelite Bay, where it is a common plant. A many-branched bush with wedge-shaped serrated leaves and large golden-yellow flower spikes, known as inflorescences, it grows up to 10 metres (30 ft) high. These plants are killed by bushfire, and regenerate from seed. The flowers attract nectar- and insect-feeding birds, particularly honeyeaters, and a variety of insects. In cultivation, ''Banksia media'' grows well in a sunny location on well-drained soil in areas with dry summers. It is more resilient than most Western Australian banksias when cultivated in areas with humid summers. Description ''Banksia media'' grows as a many-stemmed shrub generally to around 4 m (13 ft) high, though specimens up to 10 m (30 ft) high and 6 m (20&nbs ...

Lignotuber
A lignotuber is a woody swelling of the root crown possessed by some plants as a protection against destruction of the plant stem, such as by fire. Other woody plants may develop basal burls as a similar survival strategy, often as a response to coppicing or other environmental stressors. However, lignotubers are specifically part of the normal course of development of the plants that possess them, and often develop early on in growth. The crown contains buds from which new stems may sprout, as well as stores of starch that can support a period of growth in the absence of photosynthesis. The term "lignotuber" was coined in 1924 by Australian botanist Leslie R. Kerr. Plants possessing lignotubers include many species in Australia: ''Eucalyptus marginata'' (Jarrah), ''Eucalyptus brevifolia'' (snappy gum) and ''Eucalyptus ficifolia'' (scarlet gum) all of which can have lignotubers wide and deep, as well as most mallees (where it is also known as a mallee root) and many ''Banksia ...
