Tamron SP 90MM f/2.8 AF Macro | | When I saw this plant, I assumed this was a plant stem with a single blossom and a whorl of trifoliate leaves. Based on my interpretation of the online Flora of North American description of the plant, this is actually the peduncle, and what appear to be the trifoliate leaves are really ternate involucre bracts that appear almost identical to the triofoliate basal leaves. Go figure. | | Click on the photo for a larger image
