Banksia Ser. Spicigerae
''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. Taxa Five of the ''Spicigerae'' are endemic to southwest Western Australia. The other two, ''Banksia ericifolia'' (Heath-leaved Banksia) and ''Banksia spinulosa'' (Hairpin Banksia), are endemic to the east coast of Australia. It is therefore thought to be the oldest of the series, having developed before the onset of aridity in the Nullarbor Plain The Null ...

Banksia Ericifolia
''Banksia ericifolia'', the heath-leaved banksia, or lantern banksia, is a species of woody shrub of the family Proteaceae native to Australia. It grows in two separate regions of Central and Northern New South Wales east of the Great Dividing Range. Well known for its orange or red autumn inflorescences, which contrast with its green fine-leaved heath-like foliage, it is a medium to large shrub that can reach high and wide, though is usually half that size. In exposed heathlands and coastal areas, it is more often . ''Banksia ericifolia'' was one of the original ''Banksia'' species collected by Joseph Banks around Botany Bay in 1770 and was named by Carl Linnaeus the Younger, son of Carl Linnaeus, in 1782. A distinctive plant, it has split into two subspecies: ''Banksia ericifolia'' subspecies ''ericifolia'' of the Sydney region and ''Banksia ericifolia'' subspecies ''macrantha'' of the New South Wales Far North Coast which was recognized in 1996.

Southwest Australia
Southwest Australia is a biogeographic region in Western Australia. It includes the Mediterranean-climate area of southwestern Australia, which is home to a diverse and distinctive flora and fauna. The region is also known as the Southwest Australia Global Diversity Hotspot, as well as Kwongan. Geography The region includes the Mediterranean forests, woodlands, and scrub ecoregions of Western Australia. The region covers 356,717 km2, consisting of a broad coastal plain 20-120 kilometres wide, transitioning to gently undulating uplands made up of weathered granite, gneiss and laterite. Bluff Knoll in the Stirling Range is the highest peak in the region, at 1,099 metres (3,606 ft) elevation. Desert and xeric shrublands lie to the north and east across the centre of Australia, separating Southwest Australia from the other Mediterranean and humid-climate regions of the continent. Climate The region has a wet-winter, dry-summer Mediterranean climate, one of five such regio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Taxonomy Of Banksia
As with other flowering plants, the taxonomy of ''Banksia'' has traditionally been based on anatomical and morphological properties of the ''Banksia'' flower, fruiting structure and seed, along with secondary characteristics such as leaf structure and growth habit. Increasingly, molecular evidence from DNA is providing important new insights into relationships within the genus and between this and other genera in the Proteaceae. The genus is placed in family Proteaceae, subfamily Grevilleoideae, tribe Banksieae and subtribe Banksiinae. The most recent complete revision is that published in Alex George's 1999 monograph for the ''Flora of Australia'' book series; this recognises two subgenera, three sections, 13 series, 77 species, 6 subspecies and 18 varieties, and treats the traditionally related genus '' Dryandra'' as separate but closely related. Recent molecular cladistic analyses have provided an alternative view in which '' Dryandra'' is shown to be nested inside, and h ...

Banksia Brownii
''Banksia brownii'', commonly known as feather-leaved banksia or Brown's banksia, is a species of shrub that grows in southwest Western Australia. A plant with fine feathery leaves and large red-brown flower spikes, it usually grows as an upright bush around two metres (7 ft) high, but can also occur as a small tree or a low spreading shrub. First collected in 1829 and published the following year, it is placed in ''Banksia'' subgenus ''Banksia'', section ''Oncostylis'', series ''Spicigerae''. There are two genetically distinct forms. ''Banksia brownii'' occurs naturally only in two population clusters between Albany and the Stirling Range in southwest Western Australia. In the Stirling Range it occurs among heath on rocky mountain slopes; further south it occurs among jarrah woodland in shallow nutrient-poor sand. It has been evaluated as critically endangered by the International Union for Conservation of Nature (IUCN); all major populations care threatened by ''P ...

Banksia Seminuda
''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'' (Swamp Banksia). 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''. Description The river banksia generally grows as a tree up to 25 metres (80 ft) tall with a usually brown to grey trunk covered with a hard grey furrowed bark. The tree trunk is often straight and tall as the species gener ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banksia Verticillata
''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 (''Phylidonyris novaehollandiae'') is the most prominent pollinator, although several other species of honeyeater, as well as bees, visit the flower spikes. A declared ''vulnerable'' species, it occurs in two disjunct populations on granite outcrops along the south coast of Western Australia, with the main population near Albany and a smaller population near Walpole, and is threatened by dieback (''Phytophthora cinnamomi'') and aerial canker ('' ...

Nullarbor Plain
The Nullarbor Plain ( ; Latin: feminine of , 'no', and , 'tree') is part of the area of flat, almost treeless, arid or semi-arid country of southern Australia, located on the Great Australian Bight coast with the Great Victoria Desert to its north. It is the world's largest single exposure of limestone bedrock, and occupies an area of about . At its widest point, it stretches about from east to west across the border between South Australia and Western Australia. History Historically, the Nullarbor was seasonally occupied by Indigenous Australian people, the Mirning clans and Yinyila people. Traditionally, the area was called ''Oondiri'', which is said to mean "the waterless". The first Europeans known to have sighted and mapped the Nullarbor coast were Captain François Thijssen and Councillor of the Indies, Pieter Nuyts, on the Dutch East Indiaman '''t Gulden Zeepaert'' (the Golden Seahorse). In 1626–1627, they charted a stretch of the southern Australian coast eas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
