Australia has one of the world's richest carnivorous plant floras, with around 187 recognised species from 6 genera. [1]

Species

The following list is derived from Australian Carnivorous Plants (2012) by Greg Bourke and Richard Nunn. [1] It notably excludes the genus Stylidium , whose members may be 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. [2]

Aldrovanda (1 species)
Byblis (8 species; endemic)
Cephalotus (1 species; endemic)
Drosera (117 species)
Nepenthes (4 species)
Utricularia (58 species)

<span class="mw-page-title-main">Droseraceae</span> Family of carnivorous flowering plants

Droseraceae is a family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three extant genera. Representatives of the Droseraceae are found on all continents except Antarctica.

<i>Byblis</i> (plant) Genus of carnivorous plants

Byblis is a small genus of carnivorous plants, sometimes termed the rainbow plants for the attractive appearance of their mucilage-covered leaves in bright sunshine. Native to Australia and New Guinea, it is the only genus in the family Byblidaceae. The first species in the genus was described by the English botanist Richard Anthony Salisbury in 1808. Eight species are now recognised.

<i>Stylidium</i> Genus of plants

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.

The genus Drosera was divided in 1994 by Seine & Barthlott into three subgenera and 11 sections on the basis of morphological characteristics.

Allen Lowrie was a Western Australian botanist. He was recognised for his expertise on the genera Drosera and Stylidium.

<i>Nepenthes tenax</i> Species of pitcher plant from Australia

Nepenthes tenax is a lowland species of tropical pitcher plant native to northern Queensland, Australia. It is the third Nepenthes species recorded from the continent and its second endemic species. Nepenthes tenax is closely related to the three other Australian Nepenthes species: N. mirabilis, N. rowaniae and N. parvula.

<span class="mw-page-title-main">Carnivorous plant</span> Plants that consume animals

Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They still generate all of their energy from photosynthesis. They have adapted to grow in waterlogged sunny places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published Insectivorous Plants, the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research.

<i>Drosera menziesii</i> Species of carnivorous plant

Drosera menziesii, the pink rainbow, is an erect or scrambling perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows in a variety of habitats, including winter-wet depressions, swamps, and granite outcrops in clay or peat sand soils or loam. D. menziesii produces small, circular carnivorous leaves along an undulating erect stem that can be .05–1.1 m (0.2–3.6 ft) high. Its pink flowers emerge from July to November.

Drosera sulphurea, the sulphur-flowered sundew, is a scrambling perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and is found in coastal areas in sandy loam, often among Cephalotus. D. sulphurea produces small, shield-shaped carnivorous leaves along stems that can be 40–60 cm (16–24 in) high. Yellow flowers bloom in September.

<i>Drosera <span style="font-style:normal;">sect.</span> Ergaleium</i> Group of carnivorous plants

Drosera sect. Ergaleium is a section of 26 species that are erect or scrambling tuberous plants in the genus Drosera. This section represents a natural group and are taxonomically monophyletic.

<i>Drosera falconeri</i> Species of carnivorous plant

Drosera falconeri is a carnivorous plant in the family of Droseraceae. It is endemic to the Northern Territory of Australia.

<i>Drosera fulva</i> Species of carnivorous plant

Drosera fulva is a carnivorous plant in the genus Drosera and is endemic to the Northern Territory in Australia. Its semi-erect or prostrate leaves are arranged in a compact basal rosette. Oblanceolate petioles emerging from the center of the rosette are typically 2–3 mm wide at its widest. Red carnivorous leaves at the end of the petioles are small and round at 2–3 mm in diameter. Inflorescences are 25–45 cm (10–18 in) long with white or sometimes pink flowers being produced on 50-or-more-flowered racemes from February to May.

<i>Drosera kenneallyi</i> Species of carnivorous plant

Drosera kenneallyi is a carnivorous plant in the genus Drosera and is endemic to the Kimberley region in northern Western Australia. Its leaves are arranged in a compact basal rosette appressed to the soil. Narrowly oblanceolate petioles emerging from the center of the rosette are typically 1.5–2.2 mm wide at their widest. Red carnivorous leaves at the end of the petioles are small at 2–3 mm in diameter and elliptic to broadly ovate. Inflorescences are 12.5–20.5 cm (5–8 in) long with white flowers being produced on 10- to 20-flowered racemes from November to December.

<i>Drosera lanata</i> Species of carnivorous plant

Drosera lanata is a carnivorous plant in the genus Drosera and is endemic to the Northern Territory and Queensland in Australia. Its leaves are arranged in a compact basal rosette. Narrow linear petioles less than 2 mm wide emerge from the center of the rosette and hold carnivorous leaves at the end. Both petioles and the center of the rosette are densely covered in silvery dendritic hairs. These dendritic hairs afford the plant insulation and allow it to trap morning dew for additional moisture during the dry season. The leaf lamina is maroon-red and 2 mm long by 2.5 mm wide.

<i>Drosera petiolaris</i> Species of carnivorous plant

Drosera petiolaris is a carnivorous plant in the genus Drosera and is the eponymous species of the petiolaris species complex, which mostly refers to the entire subgenus Lasiocephala. It is native to Northern Australia, including the northern regions of Western Australia, the Northern Territory, and Queensland, and New Guinea; this distribution is the largest in the subgenus and the only that extends beyond Australia. Its leaves are arranged in a compact basal rosette with long, narrow petioles emerging from the center of the rosette. Carnivorous leaves are held at the end of the petiole with long retentive glands.

<i>Bulletin of the Australian Carnivorous Plant Society</i>

The Bulletin of the Australian Carnivorous Plant Society was a quarterly periodical and the official publication of the Australian Carnivorous Plant Society. Established in April 1982 as Bulletin / South Australian Carnivorous Plant Society, it continued publication until 2003. In a special general meeting of society members, in September 2004, it was decided the bulletin would cease publication. Typical articles included matters of horticultural interest, field reports, literature reviews, and scientific studies. The headquarters was in Adelaide.

<i>Carnivorous Plants of Australia</i> Work by Allen Lowrie

Carnivorous Plants of Australia is a three-volume work on carnivorous plants by Allen Lowrie. The three tomes were published in 1987, 1989, and 1998, by University of Western Australia Press.
