Tryon State Park - Saturday, April 16, 2011

I rode my bike to People’s to meet for class today. We were minus four students. I rode with Meredith, Missy and Derek today, to Tryon State Park located in SW Portland, Oregon.

Today we learned about flowers!

  • Petals attract pollinators
  • Peduncle is the stem
  • Sepals protect the flower before it opens
  • The Pistil (the female) contains the Stigma, Style and Ovary
    • Stigma receives pollen
    • Style is the tube on top of the ovary
    • Ovary becomes the fruit
      • Ovul is the reproductive cell which will become the seed when fertilized by pollen
  • The Stamen (the male) contain the Anther and Filament
    • Anther produces pollen
    • Filament holds the Anther

Trillium (Trillium ovatum) have 3 leaves, 3 sepals, 3 petals, 6 stamen and 3 stigma giving Trillium it’s name meaning “in 3s”. (Pojar) The flowers are bright white attracting pollinators, turning pink/purple once pollination is complete.

Wood Violet (Viola Glabella) are sweet little yellow violets that have dark purple lines exiting the bottom 3 petals.

I really enjoy learning about plants, botany is awesome! I saw and studied so many plants and flowers today including: Western Red Cedar, Red Alder, Big-Leaf Maple, Oregon Grape, Salal, Osoberry, Salmonberry, Red Elderberry, Hawthorn, Trillium, Hellebore, Garlic Mustard, Chickweed, Wood Violet, Waterleaf, Lemon Balm, Mullein, Dandelion, Nettles, Cleavers, Wild Ginger, Skunk Cabbage, Sword Fern, Horsetail, and Scouring Rush. I need to let all of this sink in.
