Spotting

Description:

Green and white flowers with pointy petals growing in a dense cluster

Habitat:

Growing on a hill at a campsite outside Yellowstone near sagebrush

Notes:

I didn't get a great shot of it and you can't see the leaves well, but the flowers are pretty distinctive. The leaves you see actually belong to this plant http://www.projectnoah.org/spottings/124... (second photo)
