Time to start catching up on photos from this growing season.
Back in late July, Lindsay and I joined a group from Save the Dunes on a quick trip to Pinhook Bog in LaPorte County, Indiana. Led by staff from Indiana Dunes National Lakeshore, the walk down the boardwalk and back was very brief and only touched on the unique bog flora, but I used a free second to take a couple of photographs of a plant that I admire but don't see very often, Triadenum virginicum (Virginia Marsh St. John's Wort).

|Note the pointed sepals and "long" styles of Triadenum virginicum.|
Plants in the genus Triadenum were formerly treated as part of the genus Hypericum, but they are now distinguished from Hypericum due to petal and stamen characteristics. The petals of Triadenum are pink or flesh-colored (versus yellow in Hypericum). The stamens of Triadenum are in three groups of three and alternate with three large orange glands (versus being of various number and lacking glands in the flowers of Hypericum). This unique characteristic of the flowers of plants in the genus Triadenum is the origin of their Latin name, as Triadenum means "three glands."
