I stumbled upon this photo from N Carolina and got puzzled... Four petals, eight drooping stamens, one undivided pistil. And funny looking jar-like fruits. Not sure if they belong to these flowers, but looks like they are also four-parted. The author of the photo has no clue what this is. Anyone gets an idea? http://fotki.yandex.ru/users/spelena10/view/292396 Andrey
Thank you, Daniel! It is Rhexia. A single genera from Melastomataceae growing in US. FNA does not have it online yet. And none of my keys even mentioned this family. Here are nice pictures of it: http://www.duke.edu/~jspippen/plants/rhexia.htm
Thanks for including that link, Andrey. There are lots of nice looking and useful photos on that site.
Sure! This guy definitely knows what his Nikon is for. But I want to ask him to fix one identification on the Utah page. One for Delphinium sp. To my guess this should be Polemonium ceruleum, Jacob's Ladder. Don't you think? http://www.duke.edu/~jspippen/utah/utahwildflowers.htm
Sure does not look like Delphinium. And one more: those named "Oenothera coronopifolia" -- leaves are wrong for coronopifolia. Looks more like O.macrocarpa.
That's true, O. coronopifolia is a caulescent, taller species, whereas one in Jeff's picture is more cespitose. I identified it as O. caespitosa. Just one another acaulescent species occurs only in the South Utah. O. macrocarpa does not grow in the wild here. Here is my pic of O. caespitosa, also with oak leaves in the background.
