Tuberous Drosera graniticola - indumenta

Drosera graniticola N.G.Marchant

The epithet, graniticola, is derived from the name of the rock type granite, a granular, crystalline rock of quartz, feldspar and mica, along with the Latin suffix -cola (dwelling), referring to the preferred habitats in which this species grows.

Western Australia – in the region bordered by Hyden, Varley and Kulin.

Grows in washes, as well as the declivities on and around the aprons of granite outcrops in gritty, loam soils.

Drosera gunniana (Planch.) de Salas

The epithet, gunniana, honours Ronald Campbell Gunn (1808–81), botanist, who arrived in Tasmania in 1830. Gunn became a passionate biologist and travelled extensively, dedicating himself to collecting, recording and forwarding specimens of Tasmanian flora and fauna to W.J Hooker.

New South Wales, Victoria, South Australia, Tasmania and New Zealand north of Auckland.

Common in woodland, grassy woodland and extending onto open, grassy habitats such as lawns, at low to mid elevations (<200m).

Drosera heterophylla Lindl.

The epithet, heterophylla, is from the Greek heteros (different) and phyllon (leaf), a reference to the two types of leaves it produces, namely the broadly reniform carnivorous leaves and the non-carnivorous bracts (prophylls).

Western Australia – Mingenew; Wongan Hills; Perth.

Grows on the margins of swamps, often standing in shallow water, wet clay flats, washes of granite outcrops and winter streams. All locations dry out in summer.

Drosera hirsuta Lowrie & Conran

The epithet, hirsuta, is from the Latin hirsutus (hirsute), in reference to the dense, non-glandular, hairy indumentum which covers only the uppermost portion of the major axis and the entire inflorescence, including the pedicels and abaxial surfaces of the sepals.

Western Australia – Occurs from Clackline, to the east of Perth, and north to Kalbarri.

Grows in white or yellow sandy soils on heathland.

Drosera hookeri R.P.Gibson, B.J.Conn & Conran

The epithet, hookeri, honours Sir Joseph Dalton Hooker (1817–1911), who recognised this taxon as a distinct species and provided the manuscript name Drosera foliosa which was used in 1848 by J.É. Planchon. Sir Joseph Dalton Hooker was one of the greatest British botanists and explorers of the 19th century. Drosera foliosa Hook.f ex Planch. was published in 1848. Unfortunately, this name was used earlier for a Drosera species from the U.S.A., D. foliosa Elliott, which was published in his A sketch of the botany of South Carolina 1: 376 (1817).

South Australia – Mt Remarkable; lower Eyre Peninsula; Adelaide Hills; Naracoorte; Kangaroo Island. TAS. – West Tamar; Launceston; George Town; Dorset; Horsham; Meander Valley; King Island. VIC. – Grampians; Latrobe; Wodonga; Horsham; Ararat; Mildura. A.C.T. – Mt Tennent. N.S.W. – Bega Valley; Bathurst; Ballina; Tamworth; Cessnock; Upper Hunter. QLD – Stanthorpe; Herberton; Duaringa; Dalrymple; Jericho.

Grows in loam soils in depressions on granite outcrops; black soil swampland margins; herb fields; and on low, open shrub lands.

Drosera hortiorum T.Krueger & G.Bourke.

The specific epithet honours Fred Hort (1937–) and Jean Hort (1952–), enthusiastic field botanists, nature photographers, and volunteers at the Western Australian Herbarium who found this species at the Wandoo National Park type location in 1987.

Known from Glen Forrest, Wandoo National Park (near York, east of Perth) and two additional sites in the wheatbelt region near York and Wickepin.

In the western part of its range, D. hortiorum appears to be associated with low granite outcrops and granite slopes where it grows in poorly drained clay loam with Borya sp. In the eastern part of its range, D. hortiorum has been recorded from within and near shallow drainage channels and moist sandplains in sandy clay.

Drosera huegelii Endl.

The epithet, huegelii, honours Baron Charles von Hügel (1795–1870), who collected this species in January 1834 from the King George Sound region somewhere near the early (1829) settlement of Albany, Western Australia.

Western Australia – Coolup; Beaufort; Cranbrook; south coastal regions from Augusta to Cape Arid.

Grows on the margins of swamps, winter-wet depressions and coastal heathlands in sandy soils. Also found in the skeletal, gritty, black silt soils covered with moss on the aprons of granite outcrops.

Drosera huegelii var. phillmanniana Y.-A.Utz & R.P.Gibson

The epithet phillmanniana honours Phillip (Phill) Mann (1951-2014), a Western Australian carnivorous plant enthusiast and taxonomist who recognized the distinctiveness of this taxon and brought it to the attention of the authors.

Western Australia - only known from the highest mountains of the Stirling Range.

Occurring above ca. 800 m elevation in open, wind-exposed montane heath

Drosera humilis Planch.

The epithet, humilis, is from the Latin humilis (low growing), in reference to its small, low growth habit.

Western Australia – known to be a common species from the Moore River north to Kalbarri, and inland to Ajana in the north and Wongan Hills in the south.

Grows in well-drained, winter-wet, deep white or yellow sandy soils amongst low shrubs on heathland on the northern sand plains. Near the Zuytdorp National Park, D. humilis grows in red sandy soils.

Drosera indumenta Lowrie & Conran

The epithet, indumenta, is from the Latin indumentum (hair-covering), in reference to the glandular, hairy indumentum covering all of the major axis from base to apex, pedicels and sepals.

Western Australia – Occurs from Casuarina to Margaret River.

Grows in waterlogged, winter-flooded (to a shallow depth) swampland flats and their margins, in black sandy soils made up of a mixture of white silica sand and humus derived from decomposed leaf-fall vegetation, in association with reed-like sedges (upon which it commonly climbs and attaches) and paperbark trees (Melaleuca species). These habitats can dry out in summer, but generally maintain their soil moisture for the majority of the year.
