Private Tuberous Drosera aberrans - calycina

Drosera aberrans (Lowrie & Carlquist) Lowrie & Conran

The epithet is the Latin aberrans (departing), meaning a departure from the normal, in reference to this species’ stoloniferous habit, by which manner it differs from its relative, Drosera whittakeri.

Widespread across the inland southern mallee regions of South Australia east of the Mount Lofty Ranges, southern and central Victoria to east of Wilson’s Promontory. Two collections have been recorded from southern central New South Wales.

Common in a wide range of soil types from sands to lateritic gravels and limestone-derived clays. Plants grow in full sun or partial shade in mallee woodlands, heaths and open, forested regions.

Drosera andersoniana W.Fitzg. ex Ewart & Jean White

Drosera andersoniana was first described and named, though not validly published, by forester and prospector William Vincent Fitzgerald (1867–1929). The species was later validly published in 1909 by Alfred James Ewart (1872–1937), an English-Australian Botanist, and Jean White-Haney (1877–1952) an Australian Botanist. It was not possible to identify the Anderson after whom Fitzgerald named the taxon.

Western Australia – Boorabbin; Bruce Rock; Cowcowing; Emu Rock; Hyden; east of Southern Cross; Wongan Hills; Wubin; Yanneymooning Rock; Yellowdine.

This species grows in the wheat-belt region in loam soil washes; deep loamy gullies; clayey sand; ironstone gravels near granite rock outcrops; and in sandy soils between open low scrub.

Drosera atrata T.Krueger, A.Fleischm. & G.Bourke

The specific epithet is derived from the Latin atratus (=blackened) and refers to the very dark red to blackish red flower colour of this species, which is the darkest petal colour known in the genus Drosera (under some lighting conditions appearing almost black).

Western Australia - between Warradarge in the north and Badgingarra in the south.

It occurs in low kwongan heath on the upper slopes of lateritic hills in poorly drained sandy clay with laterite.

Drosera auriculata Backh. ex Planch.

The epithet, auriculata, is from the Latin auriculatus (having long, ear-shaped auricles) in reference to the cauline-leaved lamina, which has long lobes at the angles.

South Australia – Bordertown; Glencoe; swamps between Mt Compass and Mt Moon; Naracoorte; Peters Creek; Kangaroo Island. Victoria – Raymond Island; Middle Tarwin; Snake Island; San Remo; Wilsons Promontory; Brisbane Ranges. New South Wales – Braidwood; Kempsey; Mulgoa; Nelligen; Nowra; Pigeon House Range; Yetholme; Ilford; Bilpin. Tasmania– Bruny Island; between Deadman’s Bay and Lousy Bay; Finders Island; King Island; Mt Nelson; Corinna; Ulverstone. New Zealand – throughout the North Island and northern tip of the South Island.

Grows in laterite and sandy clay (South Australia); grey sand in dry situations under Eucalyptus (Tasmania); open poorly drained areas in moss pads on clay flats or in areas of regenerating bush often at the base of tea tree (New Zealand).

Drosera basifolia (N.G.Marchant and Lowrie) Lowrie

The epithet, basifolia, is from the Latin basis (foot), and folium (leaved), in reference to the many, outward-facing laminae that are crowded together at the base of the plant.

Western Australia – Calingiri; Corrigin; Quairading; Wongan Hills.

Grows in sandy clay in winter-wet depressions amongst low shrubs. All locations dry out in summer.

Drosera bicolor Lowrie & Carlquist

The epithet, bicolor, is derived from the Latin bi (two) and coloris (colour), in reference to its bi-coloured (white with reddish spots near the base) flowers.

Drosera browniana Lowrie & N.G.Marchant

Named in honour of Andrew Brown, an enthusiast of native orchids (co-author of Orchids of southwest Australia), a botanist and research scientist at the Department of Environment and Conservation. Brown discovered the first population of this taxon on Hatter Hill.

Western Australia – Hatter Hill; Mt Holland; North Ironcap; Middle Ironcap; South Ironcap; all in the Forrestania region.

Commonly grows in small, surface rock depressions, or panholes, known by the Australian aboriginal name, gnammas.

Drosera bulbigena Morrison

The epithet, bulbigena, is from the Latin bulbus (bulb) and genus (offspring), in reference to the species’ ability to produce adventitious dropper roots from which additional tubers develop asexually into individual plants in the following growing season. Western Australia – Pinjarra; Coolup; Brunswick Junction; Perth.

Grows on the margins of swamps and low-lying areas in winter-wet, peaty sand soils.

Drosera bulbosa Hook.

The epithet, bulbosa, is derived from the Latin bulbosus (bulbous), in reference to its bulb-like tuber.

Western Australia – Hyden; Merredin; Miling; Mogumber; Jurien Bay; Perth.

Grows mainly in loam soils in moss pads around the aprons of granite rock outcrops in outer wheat-belt areas; scattered throughout the Darling Range east of Perth in association with granite outcrops, where winter rain runoff is greatest.

Drosera bulbosa subsp. coronata R.P.Gibson

The subspecific epithet coronata refers to this characteristic crown-like style arrangement.

Western Australia - only known from two locations near the small Wheatbelt towns of Mingenew and Mullewa, around 300 to 400 km north of Perth.

This subspecies grows in loamy soils in Acacia woodlands at the bases of steep slopes and near river margins.

Drosera calycina Planch.

The epithet, calycina, is derived from the Latin calycinus (with a well developed calyx), referring to the fact that the flower’s sepals are larger than its petals.

Western Australia – Darlington; Dwellingup; Gidgegannup; Mt Lesueur.

Grows in laterite-loam soils in jarrah woodlands.
