I'm hoping this is the appropriate forum for this post; it was the only one that seemed fit.
This summer I came across a wildflower that looks very similar to the one posted below. I got this picture from an Alaskan photography site, but they couldn't identify it either. I have one dried and preserved and was debating sending it in to UAA's biology program, but thought a fellow Alaskan may be able to help me.
It stands about a foot tall and grows on wet ground. The stem is thin, straight, and green. About three quarters of the way up the stem before you reach the flower, four leaves come out at a horizontal angle exactly 90 degrees apart from one another. They have a greenish color, but can sometimes have a purplish tint. The flower itself has randomly spaced pink buds that form a sphere. They bloom into individual white flowers usually within 24 hours of one another. Most of the time they will all flower and die at the same time (late June to early July). They seem to be very rare and don't grow in clusters. Sometimes there are two or three in one area, but usually they are not that dense. I find them growing on the outside of alder and willow timbers and sometimes on the side of well-drained tundra hills. Any insight into what exactly this flower could be? I've done tens of hours of researched and found absolutely nothing.
