Cephalotus is a genus which contains one species, Cephalotus follicularis the Albany pitcher plant, a small carnivorous pitcher plant. The pit-fall traps of the modified leaves have inspired the common names for this plant, which also include Western Australian pitcher plant, Australian pitcher plant, or fly-catcher plant. It is an evergreen herb that is endemic to peaty swamps in the southwestern corner of Western Australia. As with the unrelated Nepenthes, it catches its victims with pitfall traps.
Stylidium is a genus of dicotyledonous plants that belong to the family Stylidiaceae. The genus name Stylidium is derived from the Greek στύλος or stylos, which refers to the distinctive reproductive structure that its flowers possess. Pollination is achieved through the use of the sensitive "trigger", which comprises the male and female reproductive organs fused into a floral column that snaps forward quickly in response to touch, harmlessly covering the insect in pollen. Most of the approximately 300 species are only found in Australia, making it the fifth largest genus in that country. Triggerplants are considered to be protocarnivorous or carnivorous because the glandular trichomes that cover the scape and flower can trap, kill, and digest small insects with protease enzymes produced by the plant. Recent research has raised questions as to the status of protocarnivory within Stylidium.
Adenanthos is a genus of Australian native shrubs in the flowering plant family Proteaceae. Variable in habit and leaf shape, it is the only genus in the family where solitary flowers are the norm. It was discovered in 1791, and formally published by Jacques Labillardière in 1805. The type species is Adenanthos cuneatus, and 33 species are recognised. The genus is placed in subfamily Proteoideae, and is held to be most closely related to several South African genera.
Banksia repens, the creeping banksia, is a species of shrub in the plant genus Banksia. It occurs on the south coast of Western Australia from D'Entrecasteaux National Park in the west to Mount Ragged in the east.
Stylidium laricifolium, commonly known as giant trigger-plant, larch-leaf or tree triggerplant, or is a species of flowering plant in the family Stylidiaceae and is endemic to eastern Australia. It is a perennial subshrub with many linear leaves crowded along its few stems, the flowers white to pale pink and arranged in a single main panicle and smaller racemes.
Stylidium repens, the matted triggerplant, is a dicotyledonous plant that belongs to the genus Stylidium. S. repens is endemic to Australia and is found primarily in southwest Western Australia. This species is a creeping or scrambling triggerplant, which can spread over large areas as a tangled mat of stems and aerial roots. The older stems are grey whereas younger stems appear red and have terminal rosettes of small leaves, five mm to one cm in length. When the rains come, new roots and a one to three flowers emerge from the terminal rosettes. This is the only species of triggerplant known to regularly flower twice a year—in autumn and late spring. Pollination, which is typically very specialized in this genus, is achieved with a variety of insects in this species.
Adenanthos sericeus, commonly known as woolly bush, is a shrub native to the south coast of Western Australia. It has bright red but small and obscure flowers, and very soft, deeply divided, hairy leaves.
Stylidium aceratum is a dicotyledonous plant that belongs to the genus Stylidium. It occurs within the south west region of Western Australia
Amphibolis antarctica is a species of flowering plant in the family Cymodoceaceae. It is referred to by the common names wire weed or sea nymph, and is a seagrass found in coastal waters of southern and western Australia.
The flora of Western Australia comprises 10,842 published native vascular plant species and a further 1,030 unpublished species. They occur within 1,543 genera from 211 families; there are also 1,335 naturalised alien or invasive plant species more commonly known as weeds. There are an estimated 150,000 cryptogam species or nonvascular plants which include lichens, and fungi although only 1,786 species have been published, with 948 algae and 672 lichen the majority.
Stylidium perplexum is a species of triggerplant that is endemic to south-west Western Australia. It is a tuberous species that has many stems and has been described as "somewhat shrubby" at 15–40 cm tall. The linear leaves can be 2 cm long and are arranged around the stem in a rosette at the stem apices. The 8–19 cm tall scapes bear 6 to 14 flowers that are white with purple accents and corolla lobes that are laterally paired and 4–6 mm long.
Stylidium armeria, the thrift-leaved triggerplant, is a species of Stylidium that is native to Australia. It is an herbaceous perennial that grows from 50 to 100 cm tall. Narrowly lanceolate to narrowly oblanceolate leaves, about 15–40 mm long, are tufted at the base and are erect to spreading. Inflorescences produce 25–100 dark pink-magenta flowers that bloom August to February in its native range.
Gahnia trifida, the coastal saw-sedge, is a tussock-forming perennial in the family Cyperaceae, endemic to southern Australia.
Stylidium spathulatum is a dicotyledonous plant that belongs to the genus Stylidium. The species is informally named the creamy triggerplant for the colour of its flowers.
Adenanthos obovatus, commonly known as basket flower, or, jugflower, is a shrub of the plant family Proteaceae endemic to Southwest Australia. Described by French naturalist Jacques Labillardière in 1805, it had first been collected by Archibald Menzies in 1791. Within the genus Adenanthos, it lies in the section Eurylaema and is most closely related to A. barbiger. A. obovatus has hybridized with A. detmoldii to produce the hybrid A. × pamela. Several common names allude to the prominent red flowers of the species. It grows as a many-stemmed spreading bush up to 1 m (3.3 ft) high, and about 1.5 m (4.9 ft) across, with fine bright green foliage. Made up of single red flowers, the inflorescences appear from April to December, and peak in spring.
Novae Hollandiae Plantarum Specimen is a two-volume work describing the flora of Australia. Facsimiles of the originals can be found in the online Biodiversity Heritage Library (Vol.1) and Vol 2).
Ernest Charles Nelson's taxonomic arrangement of Adenanthos was the first modern-day arrangement of that plant genus. First published in his 1978 Brunonia article "A taxonomic revision of the genus Adenanthos (Proteaceae)", it superseded the arrangement of George Bentham, which had stood for over a hundred years. It was updated by Nelson in his 1995 treatment for the Flora of Australia series of monographs.
Adenanthos cuneatus, also known as coastal jugflower, flame bush, bridle bush and sweat bush, is a shrub of the family Proteaceae, native to the south coast of Western Australia. The French naturalist Jacques Labillardière originally described it in 1805. Within the genus Adenanthos, it lies in the section Adenanthos and is most closely related to A. stictus. A. cuneatus has hybridized with four other species of Adenanthos. Growing to 2 m high and wide, it is erect to prostrate in habit, with wedge-shaped lobed leaves covered in fine silvery hair. The single red flowers are insignificant, and appear all year, though especially in late spring. The reddish new growth occurs over the summer.
George Bentham's taxonomic arrangement of Adenanthos was the first comprehensive taxonomic arrangement of that plant genus. It was published in 1870 in his landmark flora of Australia, Flora Australiensis. It would stand for over a hundred years before being superseded by the 1978 arrangement of Ernest Charles Nelson.
Stylidium nymphaeum is a climbing triggerplant found along the southern coast of Southwest Australia. The species uses the curved tips of its leaves to clamber over nearby plants, attaining a height between 1.4 and 2.5 metres. These leaves are long and slender, between 15 and 75 millimetres in length and 0.8 to 2 millimetres in width, are hairless, and have an entire margin. The scape is also hairless. The flowers are pink to purple, appearing from December or January to May.
