Ranunculus Arvensis (Corn Buttercup, Devil-on-all-sides, Scratch Bur) is a plant species of the genus Ranunculus. It was formerly a common annual arable weed in Britain, but is now rare.
Ranunculus is a large genus of about 400 species of plants in the Ranunculaceae. It includes the buttercups, spearworts, water crowfoots and the lesser celandine (but not the greater celandine of the poppy family Papaveraceae). They are mostly herbaceous perennials with bright yellow or white flowers (if white, still with a yellow centre); some are annuals or biennials. A few have orange or red flowers and occasionally, as in R. auricomus, petals may be absent. The petals are often highly lustrous, especially in yellow species.
All Ranunculus species are poisonous when eaten fresh by cattle, horses, and other livestock, but their acrid taste and the blistering of the mouth caused by their poison means they are usually left uneaten.
I found this flower on our return way from one of the valleys of Arasbaran Biosphere protected area, I couldn’t believe how tiny and cute it was… It is almost 5mm in diameter… 🙂
