![]() ![]() ![]() The split (and often re-recognized) genera include Arcteranthis Greene, Beckwithia Jeps., Callianthemoides Tamura, Coptidium (Prantl) Beurl. A proposal to split Ranunculus into several genera have thus been published in a new classification for the tribe Ranunculeae. Ceratocephala, Halerpestes, Hamadryas, Laccopetalum, Myosurus, Oxygraphis, Paroxygraphis and Trautvetteria. Molecular investigation of the genus has revealed that Ranunculus is not monophyletic with respect to a number of other recognized genera in the family – e.g. Unable to see, Coyote made eyes from the buttercup. In the legend Coyote was tossing his eyes up in the air and catching them again when Eagle snatched them. In the interior of the Pacific Northwest of the United States the buttercup is called “Coyote’s eyes” - ʔiceyéeyenm sílu in Nez Perce and spilyaynmí áčaš in Sahaptin. A popular children’s game involves holding a buttercup up to the chin a yellow reflection is supposed to indicate fondness for butter. The name buttercup may derive from a false belief that the plants give butter its characteristic yellow hue (in fact it is poisonous to cows and other livestock). This probably refers to many species being found near water, like frogs. ![]() The name Ranunculus is Late Latin for “little frog,” from rana “frog” and a diminutive ending. Some species are popular ornamental flowers in horticulture, with many cultivars selected for large and brightly coloured flowers Naming Ranunculus species are used as food plants by the larvae of some Lepidoptera species including Hebrew Character and Small Angle Shades. aquatilis, a third, intermediate leaf type occurs. They have two different leaf types, thread-like leaves underwater and broader floating leaves. The Water crowfoots ( Ranunculus subgenus Batrachium), which grow in still or running water, are sometimes treated in a separate genus Batrachium (from Greek batrachos βάτραχος: frog, etymology comparable to ranunculus itself). 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. The petals are often highly lustrous, especially in yellow species. There are usually five petals, but sometimes six, numerous, or none, as in R. A few species have orange or red flowers. They are mostly herbaceous perennials with bright yellow or white flowers (if white, still with a yellow centre) some are annuals or biennials. Members of the genus include the buttercups, spearworts, water crowfoots and the lesser celandine.
