Distribution of D. petiolaris in Australia

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. [1] [2]

Drosera petiolaris was first formally described by the Swiss botanist Augustin Pyramus de Candolle in the first volume of Prodromus Systematis Naturalis Regni Vegetabilis in 1824. In this description, de Candolle cited an unpublished description by Scottish botanist Robert Brown as a basis for his valid description of the species. The type specimen was collected at the Endeavour River in Queensland by Joseph Banks and Daniel Solander on the first voyage of James Cook aboard HMS Endeavour. [2] [3]

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

Drosera ordensis is a species of sundew, native to Australia and part of the "petiolaris complex" of sundews making up the subgenus Lasiocephala. Compared to many petiolaris sundews, it has wide petioles, which are densely covered in silvery hairs. It usually forms rosettes 8 cm across, although plants up to 20 cm in diameter have been reported.

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

Drosera dilatatopetiolaris is a carnivorous plant in the genus Drosera and is endemic to Australia, being found in both Western Australia and the Northern Territory. Its leaves are arranged in a rosette and commonly produces plantlets, eventually forming large clumps that can be over 1 ft (0.3 m) across. Green petioles emerging from the center of the rosette are typically 3–5 mm wide, but can vary. Red carnivorous leaves at the end of the petioles are small and round, with most resting on the soil surface. Inflorescences are 18 cm (7 in) long with white flowers being produced from April to May. It has a diploid chromosome number of 2n = 12.

<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>Pomaderris aspera</i> Species of tree

Pomaderris aspera, commonly known as hazel pomaderris, is a species of flowering plant in the family Rhamnaceae and is endemic to south-eastern Australia. It is a shrub or small tree with elliptic to lance-shaped or egg-shaped leaves and greenish-yellow flowers.

<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 paradoxa</i> Species of carnivorous plant

Drosera paradoxa is a carnivorous plant in the genus Drosera and is endemic to the Northern Territory and Western Australia. It is a perennial herb with a woody stem that can grow as tall as 30 cm (12 in). The leaves on the single terminal rosette are erect or horizontal and held at the end of linear petioles, which are typically 20–35 mm long at flowering time. The carnivorous leaves are sub-orbicular and small at 2.5–3 mm wide and 2–3 mm long. Inflorescences are 20–40 cm (8–16 in) long with pink or white flowers being produced on 50- to 70-flowered crowded racemes from July to September during the dry season.
