Lepidium aschersonii, also known as spiny peppercress, is a species of plant in the cabbage family. It is native to mainland southern Australia.
The species grows as a perennial herb up to about 30 cm in height. It has intricately branched stems; the smaller branches are spiny, and the whole plant becomes spinier with increasing age and aridity. The leaves may be up to 12 cm long at the base of the plant and but smaller farther up the stem. The inflorescence is an inconspicuous greenish raceme terminating in a spine. The flowers are less than a millimetre long. The fruits are oval pods 3.5–4.5 cm long by 2.5–3 cm wide. [1]
The species is found in New South Wales and Victoria, with an isolated population in Western Australia. It occurs around swamps and saltmarshes on heavy soils which are regularly waterlogged or flooded. [1]
The species has declined in range and abundance since European settlement in Australia. It is threatened by invasive plants, grazing by rabbits and livestock, and altered hydrology. It has been declared Vulnerable under Australia’s EPBC Act. [1]
Lepidium is a genus of plants in the mustard/cabbage family, Brassicaceae. The genus is widely distributed in the Americas, Africa, Asia, Europe, and Australia. It includes familiar species such as garden cress, maca, and dittander. General common names include peppercress, peppergrass, pepperweed, and pepperwort. Some species form tumbleweeds. The genus name Lepidium is a Greek word meaning 'small scale', which is thought to be derived from a folk medicine usage of the plant to treat leprosy, which cause small scales on the skin. Another meaning is related to the small scale-like fruit.
Stenocereus eruca, commonly known as the creeping devil, is a member of the family Cactaceae. It is one of the most distinctive cacti, a member of the relatively small genus Stenocereus. It is endemic to the central Pacific coast of Baja California Sur, and is found only on sandy soils, where it forms massive colonies.
Lepidium draba, the whitetop or hoary cress, or Thanet cress, is a rhizomatous perennial flowering plant in the family Brassicaceae. It is native to western Asia and southeastern Europe and widely introduced elsewhere.
Onopordum illyricum is a species of thistle known by the common name Illyrian thistle, or Illyrian cottonthistle. It is native to southwestern Europe, but has been introduced into Australia and California, where it has become a noxious weed.
Lepidium densiflorum is a species of flowering plant in the mustard family known by the common names common pepperweed and prairie peppergrass.
Lepidium flavum is a species of flowering plant in the mustard family known by the common name yellow pepperweed. It is native to California, Nevada, and Baja California, where it grows in the Sonoran and Mojave Deserts. The species epithet flavum is Latin for yellow and indicates its flower colour.
Lepidium fremontii, the desert pepperweed, is a species of flowering plant in the mustard family which is native to the southwestern United States, where it grows on sandy desert flats and the rocky slopes of nearby hills and mountains. It takes its scientific name from John C. Frémont.
Calamus australis, commonly known as wait-a-while, hairy mary or lawyer cane, is a plant in the palm family Arecaceae which is endemic to the rainforests of north east Queensland, Australia. Like other species in the genus Calamus, this is a climbing plant with a very long and flexible stem. It uses sharp strong hooks on the fronds and tendrils to attach itself to other vegetation, such as taller established trees, thus gaining support that enables it to grow higher towards the canopy. This species is very similar to C. radicalis, with which it coexists, but is smaller in almost all respects.
Randia moorei, commonly known as the spiny gardenia, is a rare Australian shrub growing in the far north eastern areas of the state of New South Wales and adjacent areas in Queensland. The habitat is subtropical rainforest north of Lismore.
Swainsona behriana, commonly known as Southern Swainson-pea, is a small perennial plant in the family Fabaceae that is native to Australia. It grows to 15 cm high, has hairy stems and pinnate leaves that are 3 to 5 cm long. Racemes of 2 to 7 purple pea flowers are produced from August to January in the species' native range. The pods that follow are 10 to 18 mm long.
Corynocarpus rupestris, commonly known as the Glenugie karaka, is a rainforest tree found in eastern Australia. It is a rare plant with a ROTAP rating of 2VC-t. There are two sub-species; arborescens is a small hairless shrub or tree up to 13 metres tall with a stem diameter up to 40 cm (16 in), and sub-species rupestris grows only to 6 metres, with a stem diameter up to 17 cm (6.7 in).
Alluaudia montagnacii is a rare species of flowering plants belonging to the family Didiereaceae.
Lepidium nesophilum is a species of flowering plant in the mustard and cabbage family that is endemic to the subtropical Lord Howe Island in the Tasman Sea between Australia and New Zealand.
Balintore is a small farming community in south west Victoria, Australia. It is approximately 15 km north of Colac.
Lepidium heterophyllum,, is a species of flowering plant in the mustard family which is native to parts of western Europe, growing in shingle banks, wasteland or cultivated fields.
Lepidium coronopus,, is a species of flowering plant in the mustard family which is native to parts of Africa, western Asia and Europe, growing in shingle banks, wasteland or cultivated fields.
Lepidium monoplocoides, the winged peppercress, is a nationally endangered plant species endemic to inland south-eastern Australia. The winged peppercress can grow from 15 up to 20 centimetres tall. This plant has long, slender leaves. Because of destruction of habitat, this plant is endangered. The winged peppercress has green-brown flowers which grow at the end of stems.
Lepidium foliosum, commonly known as leafy peppercress, is a shrubby species of plant found in southern regions of Australia, usually close to the coast. The herbaceous species is shrubby in form, with hairless leaves and stem, and resembles others plants of the mustard family Brassicaceae.
Ixodia achillaeoides, commonly known as mountain daisy, is a species of flowering plant in the family Asteraceae and is found in South Australia and Victoria. It is a small shrub with sticky, smooth branchlets and small white flowers in spring and summer.
