Dryandra Ser. Armatae
''Dryandra'' ser. ''Armatae'' is an obsolete series within the former genus ''Dryandra'' (now ''Banksia'' ser. ''Dryandra''). It was first published by George Bentham in 1870, and was given a new circumscription by Alex George in 1996, but was ultimately discarded in 2007 when Austin Mast and Kevin Thiele sunk ''Dryandra'' into '' Banksia''. According to Bentham Bentham's definition of ''D.'' ser. ''Armatae'' was "Flower-heads usually large, mostly terminal, enclosed in floral leaves longer than the flowers. Involucres broad. Perianths above 1 in. long. Stigmatic end of the style slender, often scarcely distinct. Leaves with prickly teeth or lobes.". The placement and circumscription of the series may be summarised as follows: :''Dryandra'' (now ''Banksia'' ser. ''Dryandra'') :: ''D.'' sect. ''Eudryandra'' :::''D.'' ser. ''Armatæ'' ::::''D. quercifolia'' (now '' B. heliantha'') ::::''D. praemorsa'' (now '' B. undata'') ::::''D. cunea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dryandra Armata (Curtis's Botanical Magazine Plate 3236)
''Banksia armata'', commonly known as prickly dryandra, is a species of often sprawling shrub that is endemic to Western Australia. It has deeply serrated leaves with sharply pointed lobes and spikes of about 45 to 70 yellow flowers. Description ''Banksia armata'' grows as a sprawling, spreading or upright shrub that typically grows to a height of and sometimes forms a lignotuber. It has deeply serrated leaves that are long and wide with five to thirteen sharply pointed, wedge-shaped to narrow egg-shaped lobes on each side. The flowers are arranged in spikes of between 45 and 70, each flower with a yellow, sometimes pink perianth long. Flowering occurs from June to November and the fruit is an egg-shaped follicle long. Taxonomy Specimens of ''B. armata'' were first collected at King George Sound in December 1801 by Robert Brown. Brown published a description of the species in 1810 in '' Transactions of the Linnean Society of London'' naming it ''Dryandra armata''. ...

George's Taxonomic Arrangement Of Dryandra
Alex George's taxonomic arrangement of ''Dryandra'' was the first modern-day arrangement of that taxon. First published in ''Nuytsia'' in 1996, it superseded the arrangement of George Bentham, which had stood for over a hundred years; it would later form the basis for George's 1999 treatment of ''Dryandra'' for the ''Flora of Australia''. In accordance with contemporary thinking, George treated ''Dryandra'' as a genus, dividing it into three subgenera, the largest of which was divided into 24 series. The arrangement stood until 2007, when ''Dryandra'' was transferred into ''Banksia'' as ''B.'' ser. ''Dryandra''. No alternative has yet been proposed. Background The dryandras are a group of 94 species in the plant family Proteaceae. Endemic to south-west Western Australia, they grow in forms varying from prostrate shrubs to small trees. ''Dryandra'' was originally published at genus rank in 1810, and was still considered a genus in the 1990s when George published his infra ...

Banksia Acanthopoda
''Banksia acanthopoda'' is a species of shrub in the family Proteaceae. It grows as a small spreading shrub to 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. The botanist Alex George first described this species in 1996, naming it ''Dryandra acanthopoda''. It was renamed to its current name in 2007, when all ''Dryandra'' species were transferred to the genus '' Banksia''. It is little known in cultivation and its sensitivity to dieback is unclear (although highly likely). It has potential as a cut flower.

Banksia Xylothemelia
''Banksia xylothemelia'' is a sprawling woody shrub of the family Proteaceae endemic to southern Western Australia, one of the many species commonly known as dryandras and until recently called ''Dryandra xylothemelia''. To date it is almost unknown in cultivation. Description It grows as a sprawling shrub up to high, often with basal shoots arising from an underground lignotuber. It has woolly stems. The leaves are pinnatifid with five to nine leaflets on each side, long, wide, smooth above but woolly beneath. Flowers occur in dome shaped heads up to across, attached directly to an older stem, or on a short stalk. Flower heads contain from 80 to 100 bright yellow flowers. Each flower consists of a tubular perianth made up of four fused tepals, and one long wiry style. The styles are hooked rather than straight, and are initially trapped inside the upper perianth parts, but break free at anthesis. Seeds are produced in follicles embedded in the woody bases of the flower h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Banksia Prionophylla
''Banksia prionophylla'' is a shrub endemic to Western Australia. Known only from a single population of around 70 plants in a remote part of Western Australia, it is considered rare but not endangered. It was first discovered in 2001, and published under the genus '' Dryandra'' in 2005, before being transferred into ''Banksia'' in 2007.

Banksia Armata Var
''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 ...
