Ranunculus aquatilis

Ranunculus aquatilis

Botany Photo of the Day will have brief written entries on weekends, holidays and my vacations from April through September. I'm on vacation today. – Daniel

Thank you to marcella2@Flickr for sharing today's image with us (original image | BPotD Flickr Group Pool).

White water-crowfoot is native to ponds, lake margins, marshes and slow-flowing rivers throughout much of the northern hemisphere. In Europe, Asia and Africa, it can be found from Norway south to northern Africa. In North America, it stretches from the Arctic to Mexico (note that some treatments suggest it is distributed only in western North America, while others list all of North America).


Some photos showing the flowers are at http://popgen.unimaas.nl/~jlindsey/commanster/Plants/Flowers/SpFlowers/Ranunculus.aquatilis.html which is part of an impressive site showing the wildlife in an area.

"note that some treatments suggest it is distributed only in western North America"

I think this is misreading Jepson's account? Jepson says: "Distribution outside California: to Alaska, e N.America, Mexico" - note "eastern North America".

Thanks Ken-excellent site reference.

Ah, I should have linked here instead, Michael: USDA PLANTS database
