Ranunculus amphitrichus, commonly known as the small river buttercup, is a species of buttercup found in southeastern Australia and New Zealand. [1] [2]
Ranunculus is a genus of about 500 species of flowering plants in the family Ranunculaceae. Members of the genus include the buttercups, spearworts and water crowfoots. The petals are often highly lustrous, especially in yellow species, owing to a special coloration mechanism: the petal's upper surface is very smooth causing a mirror-like reflection. The flash aids in attracting pollinating insects and temperature regulation of the flower's reproductive organs. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds.
Ranunculus repens, the creeping buttercup, is a flowering plant in the buttercup family Ranunculaceae, native to Europe, Asia and northwestern Africa. It is also called creeping crowfoot and sitfast.
Ranunculus bulbosus, commonly known as St. Anthony's turnip or bulbous buttercup, is a perennial member of the buttercup family. It has attractive yellow flowers, and deeply divided, three-lobed long-petioled basal leaves. Bulbous buttercup is known to form tufts.
Ranunculus acris is a species of flowering plant in the family Ranunculaceae, and is one of the more common buttercups across Europe and temperate Eurasia. Common names include meadow buttercup, tall buttercup, common buttercup and giant buttercup.
Ranunculus septentrionalis, the swamp buttercup, is a species of buttercup found in North America from New Brunswick to Manitoba and from Georgia to Kansas. Although some authors treat it as a distinct species, others consider it to be a subspecies of Ranunculus hispidus.
Ranunculus sceleratus known by the common names celery-leaved buttercup, celery-leaf buttercup, and cursed buttercup is a species of flowering plant in the buttercup family Ranunculaceae. It has a circumpolar distribution in the northern hemisphere, native to temperate and boreal North America and Eurasia, where it grows in wet and moist habitats, including ponds and streambanks.
Ranunculus arvensis, the corn buttercup, devil-on-all-sides or scratch bur, is a plant species of the genus Ranunculus. It is native to Europe, but it can be found on other continents as an introduced species and sometimes a weed, including in North America and Australia. It was formerly a common annual arable weed in Britain, but is now rare there. It is most often found in moist places, such as spring puddles in meadows.
Ranunculus occidentalis, the western buttercup, is a species of buttercup found in the western United States and Canada. Its distribution extends from Alaska through British Columbia and Alberta to central California. The flower can be seen in open meadows, forests, and other generally flat areas up to an elevation of 2,200 metres (7,200 ft).
Ranunculus papulentus, commonly known as the large river buttercup, is a buttercup that is endemic to south-eastern Australia.
Ranunculus eschscholtzii is a species of buttercup known by the common name Eschscholtz's buttercup.
Ranunculus muricatus is a species of buttercup known by the common names rough-fruited buttercup and spinyfruit buttercup. It is native to Europe, but it can be found in many other places in the world, including parts of Africa, Australia, and the western and eastern United States, as an introduced species and agricultural and roadside weed. It grows in wet habitats, such as irrigation ditches. It is an annual or sometimes biennial herb producing a mostly hairless stem up to half a meter long which may grow erect or decumbent along the ground. The leaves have blades a few centimetres in length which are deeply divided into three lobes or split into three leaflets. They are hairless to hairy in texture, and are borne at the tips of long petioles. The flower has five shiny yellow petals under 1 centimetre (0.4 in) long around a lobed central receptacle studded with many stamens and pistils. The fruit is a spiny achene borne in a spherical cluster of 10 to 20.
Ranunculus sardous is a species of buttercup known by the common name hairy buttercup. It is native to Europe and it can be found in many other areas of the world, including parts of the United States and Australia, as an introduced species and a roadside and lawn weed. It grows in many types of disturbed habitat, especially in moist areas. It is an annual or biennial herb producing a mostly erect, hairy stem up to half a meter tall. The hairy leaves are usually divided into three leaflets which are borne on petioles a few centimeters in length. The flower has usually five yellow petals each up to a centimeter long and five reflexed sepals. The fruit is an achene borne in a spherical cluster of up to 35.
Ranunculus auricomus, known as goldilocks buttercup or Greenland buttercup, is a perennial species of buttercup native to Eurasia. It is a calcicole typically found in moist woods and at the margins of woods. It is apomictic, and several hundred agamospecies have been recognised.
Ranunculus lappaceus, commonly known as the common buttercup, Australian buttercup or Yarrakalgamba, is found across eastern Australia. Like buttercups elsewhere, it is a perennial herb with yellow flowers appearing in spring and summer.
Ranunculus abortivus is a species of flowering plant in the buttercup family, Ranunculaceae. Its common names include littleleaf buttercup, small-flower crowfoot, small-flowered buttercup, and kidneyleaf buttercup. It is widespread across much of North America, found in all 10 Canadian provinces as well as Yukon and the Northwest Territories, and most of the United States, except Hawaii, Oregon, California, and parts of the Southwest.
Ranunculus acaulis, in Australia and New Zealand called dune buttercup, sand buttercup or shore buttercup, is a yellow-flowered, small, fleshy herb, that grows in mats in damp places mostly near the sea. It occurs naturally in Australia, New Zealand, Chile and the Falklands. It flowers between August and April and sets seed from September till July.
Ranunculus anemoneus, commonly known as the anemone buttercup, is an endangered species of buttercup found in alpine Australia.
Ranunculus inundatus, commonly known as the river buttercup, is a species of buttercup found in eastern Australia.
Ranunculus dissectifolius is a rare species of buttercup found in alpine Australia.
