A Dragonfly rests on top of stem of a Scirpus or Woolgrass that has yellow blooms. Behind is the lake with the reflection of the clouds in sky above. Scirpus is a genus of grass-like plants, commonly known as bulrushes or woolgrass, belonging to the sedge family (Cyperaceae). They are rhizomatous perennials with triangular stems and grass-like leaves, typically found in wetlands, marshes, and along water edges, and are known for their distinctive, often woolly-looking, brown or greenish flower/seed heads. Some species, like Scirpus cyperinus (woolgrass), are valuable for wetland restoration.

Would you walk on a MA swamp? I do, with snowshoes. Here's a little part of Assabet National Wildlife Refuge.
The edges are Red Maple and Grey Birch with White Pines. Often there's more shrub than this, but the water gets deep quickly here. Woolgrass (Scirpus cyperinus) is a staple monocot, but there's more Cattail (genus Typha) by far nowadays. Marshy meadows connect to oxbow lakes. Beavers compound the complexity. This seems like newer wetland to me; somewhere drought-tolerant White Pine (Pinus strobus) were suddenly out standing in the marsh, then soon dead.

Ray Angelo explains that of the five species lumped under S. Eriophorum in Thoreau's time, only S. cyperinus (COMMON WOOL­GRASS), S. atrocinctus (DUSKY WOOL­GRASS), and S. longii (LONG'S WOOL­GRASS) are known in Concord.
