I decided to venture out to the local bog to see what had come up since the last visit in April. I went a couple of hours before sunset and had the place completely to myself. I was greeted by the hungry mosquitoes who fulfilled my donation to their blood bank. This time, the landscape of now green leaves of Ericacaeous shrubs (like Chamaedaphne calyculata pictured left) was punctuated by the white tufts of Eriophorum vaginatum (pictured right). Wetlands such as bogs have a high diversity of grasses, sedges and rushes. To an undiscerning eye, they all look the same but a careful look at their stems, leaves and fruits reveals otherwise. The easiest way to tell a sedge apart is by their triangular stem whereas grasses have round, hollow stems. Rushes have round stems like grasses but have a solid inside, called the pith. Rushes also have capsules as a fruit.
