Drosera purpurascens is a compact tuberous perennial species in the genus Drosera that is endemic to south-west Western Australia. It produces 1 erect or 2 to 5 semi-erect lateral stems that grow to 3 to 10 cm long. The compact size of the plant combined with relatively long petioles distinguish it from all other members of the section Stolonifera. It is native to a region from Mount Cooke to near Katanning and Ongerup south to the Denmark-Albany region. It grows in sand-laterite soils and flowers from July to October, flowering en masse after bushfires.
Drosera rupicola is a tuberous perennial species in the genus Drosera that is endemic to Western Australia. It produces 3 to 5 semi-erect lateral stems that grow up to 15 cm long. The turbinate tuber and mobile lamina that are capable of folding over prey distinguish it from all other members of the section Stolonifera. It is native to a large inland region from Pithara to south-east of Hyden. It grows in loamy soils near granite outcrops and flowers from July to October.
Drosera stolonifera, sometimes referred to as the leafy sundew, is a tuberous perennial species in the genus Drosera that is endemic to Western Australia. It produces 2 to 3 semi-erect lateral stems that grow 10 to 15 cm long. It is most closely related to D. purpurascens, but differs by several characteristics including height and petiole length. It is native to a number of swampy locations around Perth south to Pinjarra. It grows in peaty water-logged soils in swamp heathland and flowers from September to October. After a bushfire it will flower en masse.
Drosera sect. Stolonifera is a section of ten tuberous perennial species in the genus Drosera that are endemic to south-west Western Australia. The species all have a similar growth habit and all have fan-shaped leaves, but the morphological differences and lack of natural hybrids support the division of the D. stolonifera species complex.
Drosera erythrorhiza, the red ink sundew, is a perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in a rosette and is distinguished from the other species in section Erythrorhiza by its many-flowered cymose inflorescences with up to 50 individual flowers. D. erythrorhiza was first described by John Lindley in his 1839 publication A sketch of the vegetation of the Swan River Colony. In 1992, N. G. Marchant and Allen Lowrie described three new subspecies, thus also creating the autonym D. erythrorhiza subsp. erythrorhiza. The subspecies were separated from this variable species mostly by leaf morphology and distribution.
Drosera sect. Erythrorhiza is a section of 14 species of tuberous species in the genus Drosera. It represents a natural group of all the rosetted tuberous Drosera. Most species are endemic to Western Australia, but D. aberrans, D. praefolia, D. schmutzii, and D. whittakeri are also found in eastern Australia.
Drosera gigantea, the giant sundew, is an erect perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in sandy soils at the margins of swamps and near granite outcrops along the Western Australian coast from Albany north to just south of Geraldton. D. gigantea produces small shield-shaped leaves along many lateral branches that look like a small tree. Individual plants can grow up to 0.2–1 m (0.7–3.3 ft) tall. Because of its tall, tree-like form, it is considered one of the largest Drosera species. It is also easily cultivated and enjoys damp, humid conditions often provided in greenhouses. White flowers emerge from August to November. The red tubers of this species can grow to be 3.8 cm (1.5 in) in diameter and may be a metre below ground.
Drosera macrantha, the bridal rainbow, is a scrambling or climbing perennial tuberous species in the carnivorous plant genus Drosera that is endemic to Western Australia. It grows in a variety of habitats, including winter-wet depressions in sandy, loamy, laterite, or quartzite soils. D. macrantha produces small, cup-shaped carnivorous leaves along a long stem that can be 0.16–1.5 m (0.5–4.9 ft) high as it climbs. Its 1 in (2.5 cm) white or pink flowers emerge from June to November, blooming earlier in the more northern range.
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 moorei is a scrambling or climbing perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and grows near granite outcrops in sandy loam. D. moorei produces small, circular, peltate carnivorous leaves along glabrous stems that can be 12–35 cm (5–14 in) long. Inflorescences have two to ten yellow flowers and bloom from September to October.
Drosera stricticaulis, the erect sundew, is an erect perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and is found near watercourses and granite outcrops in sandy clay or loam. D. stricticaulis produces small, cup-shaped carnivorous leaves along green, glandular stems that can be 25 cm (10 in) high. Pink flowers bloom from July to October.
Drosera subhirtella, the sunny rainbow, is a scrambling or climbing perennial tuberous species in the carnivorous plant genus Drosera. It is endemic to Western Australia and is found in sandplains, granite outcrops, and swamp margins in sand, clay, and loam soils. D. subhirtella produces small carnivorous leaves along stems that can be 40 cm (16 in) high. Yellow flowers bloom from August to October.
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.
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.
Drosera caduca is a perennial carnivorous plant in the genus Drosera that is endemic to Western Australia. Its leaves are arranged in a rosette with one or more rosettes emerging from the root stock. It produces white flowers from December to July. Drosera caduca grows in white sandy soils on creek margins from the Edkins Range to the southern part of the Prince Regent National Park and also on Augustus Island. It was first described by Allen Lowrie in 1996; the type specimen was collected from August Island on 27 May 1993. The specific epithet caduca comes from the Latin caducus meaning dropping off early, in reference to the absence of the insect-trapping trichomes on all but the juvenile leaves. This plant is unique in the genus by its lack of the sticky traps on the mature adult leaves.
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.
