Rainy Yellow. Utricularia subulata, Slender or Zigzag Bladderwort, Hortus Botanicus, Amsterdam, The Netherlands

Here's the yellow flower of a terrestial bladderwort, Utricularia subulata. Most bladderworts' roots float in the water, but this one is anchored in wet, boggy ground. They're insectivorous; it's not the high-stemmed - awl-shaped (subulata) - flowers that capture small insects but rather bladders nestling in the wet soil.
