96 DROSERACEAE 1
Dennis I Morris,† Miguel F de Salas 2
Small annual or perennial, carnivorous herbs; roots fibrous, the primary root often reduced; tubers or small rhizomes produced in some species. Leaves spiral, sometimes whorled, often in a basal rosette; stipules present or absent; lamina either modified as active traps (not in Tas.) or with mucilage-tipped often irritable insect trapping hairs. Inflorescence terminal or axillary. Flowers bisexual, actinomorphic, hypogynous. Sepals (4)5(–8), shortly connate at the base. Petals as many as the sepals, free or basally connate. Stamens (4)5(10–20), free or basally connate, alternating with petals, anthers bilocular. Carpels 3–5; ovary superior, unilocular, placentation parietal; ovules many; styles as many as the carpels, free or united at the base, often deeply divided. Fruit a loculicidal capsule enclosed in the persistent calyx. Seeds many, small, endospermic.
A family of 3 genera with about 160 species in temperate and tropical regions of both hemispheres with Australia being a major centre of diversity. 2 genera are represented by single species: Aldrovanda vesiculosa L. (NE Australia, Eurasia) and Dionaea muscipula Ellis (Venus’ Fly-trap; SE USA). Droseraceae are placed in the Caryophyllales near the other carnivorous plant families Nepenthaceae (NE Australia, New Caledonia to S Asia, Madagascar) and Drosophyllaceae (Portugal, Spain, Morocco).
Synonymy: Aldrovandaceae, Dionaeaceae.

More common and widespread than D. arcturi at low elevations in the southwest. Morphologically similar to D. arcturi but larger and with fewer glandular leaves. The species can thrive when all leaves are glabrous and there is no possibility of insect trapping.

Drosera gracilis Planch., Ann. Sci. Nat. (Paris) ser. 3, 9: 297 (1848); Drosera peltata var. gracilis (Planch.) Benth., Fl. Austral. 2: 465 (1864).
Erect perennial herb, rhizome erect, arising from a globose tuber. Leaves, stems and tubers red. Rosette leaves normally red, soil-appressed, petiole 4.5–8.0 mm long, flattened, lamina 3–5 mm in diameter, semi-orbicular-lunate, not peltate; cauline leaves solitary or in groups of 3 or 4, crescentic, auriculate, peltate, petiole 7–8 mm long, lamina 3–6 mm in diameter. Inflorescence slender, solitary, unbranched, frequently leafless in the upper half, scape ending in a terminal raceme, 2–5-flowered; bracts c. 1.5 mm long, fimbriate. Sepals dark olive green, turning black, 2.5–3.5 mm long, narrow elliptical, hirsute. Petals white, 3.5–4.5 mm long, obovate.

Tas. (BEL, FUR, KIN?, TCH, TSE, TSR, TWE), VIC, NSW. Found in marshes, peaty heath, margins of rivers and streams from near sea level to 1050 m altitude. This taxon has a confusing nomenclature history and has been considered by many authors to be synonymous with D. hookeri and D. gunniana. For a full discussion of the nomenclature, refer to de Salas (2018). The application of the name D. peltata has changed after the Gibson et al. revision of 2012, who determined that the holotype of D. peltata was conspecific with that of D. gracilis.

Drosera foliosa Hook.f. ex Planch. Ann. Sci. Nat. (Paris) ser. 3, 9: 298 (1848); Drosera peltata var. foliosa (Planch.) Benth., Fl. Austral. 2: 465 (1864).

Basal leaves yellow-green, soil-appressed, petiole flattened, 5–14 mm long, lamina 7–11 mm wide, semi-orbicular, lunate, not peltate; cauline leaves yellow-green, with petiole 5–11 mm long, lamina 3–6 mm in diameter, crescentic, auriculate or occasionally the auriculate lobes absent. Inflorescence 1–several branched, 1–10 cm tall, branched from the base and appearing multi-stemmed, each branch terminating in short racemes from lower and upper nodes; bracts linear-lanceolate, fimbriate, c. 2.5 mm long, pedicels 5–8 mm long. Sepals green or blackish, 2.5–3.0 mm long, silky-pubescent, margins fimbriate. Petals white, 4.0–4.5 mm long, obovate, drying cream or white. Seeds black, cylindrical witha short neck, 0.6–0.7 mm long, 0.25 mm wide, surface reticulated. Flowering & fruiting Sep.–Dec.
Tas. (FUR, TNM, TSE); also Vic, SA. Found in the midlands and the north-east of the island of Tasmania in grasslands, herbfields with a grassy understorey, oped woodland and pasture, from sea level to 300 m altitude. There has been considerable confusion regarding the nomenclature and taxonomy of this group of species (see comment under D. peltata).
11 Drosera gunniana (Planch.) de Salas, Muelleria 36, 102 (2018)
Drosera peltata var. gunniana Planch., Ann. Sci. Nat. (Paris) ser. 3, 9: 297 (1848).

Erect perennial herb with an erect rhizome arising from a pink or red globose tuber. Rosette leaves soil-appressed, olive-green often suffused orange, usually present at flowering time, petiole flattened 3–14 mm long, lamina 5–10 mm in diameter, semi-orbicular-lunate, not peltate; lower cauline leaves sometimes reduced to a petiole with a minute unexpanded lamina; upper leaves yellow-green or reddish, solitary or in groups of 2–4, petiole 7–10 mm long, lamina crescentic, auriculate, peltate, 5–6 mm in diameter. Inflorescence unbranched, subtended by several vegetative internodes, (5–)8–22(–30+) mm tall, yellow-green or reddish, branching from the top-most 1 or 2 vegetative internodes, or unbranched, flowers in axillary and terminal racemes; bracts lanceolate, fimbriate, hairy, margins fimbriate. Sepals olive green, rarely dark red, turning blackish, 3–5 mm long, hirsute, margins fimbriate. Petals pink or white, 5–8 mm long, obovate. Seeds black, cylindrical with a short neck, 0.5 mm long, c. 0.25 mm wide, surfece reticulated. Flowering & fruiting Oct.–Dec.
Tas. (FUR, TCH, TNM, TSE, TSR); also SA, NSW, Vic. Found in heath and sedgeland, open forest, margins of sand dunes, among mosses in skeletal soils, from near sea level to 250 m alt. Most Australian authors have included this taxon in synonymy with D. peltata and D. hookeri, but in Tasmania these taxa exhibit sufficient differences to warrant recognition as separate species. Gibson et al. treated D. hookeri broadly, including the concept of D. gunniana in synonymy. However, in Tasmania these two taxa are easily distinguished, and occupy different environmental niches. Furthermore, both taxa grow sympatrically at many localities and flower simultaneously, remaining distinct and not hybridising.
