Nature Journaling: Mashpee River
While many non-aster wildflower species are no longer blooming by late August, there were decent sized patches of both spotted jewelweed and sweet joe-pye weed in flower at the edge of the river. Spotted jewelweed (Impatiens capensis), also called spotted touch-me-not, is a common wetland annual that often grows 3 to 5 feet tall and has bright orange to yellow flowers. The flowers are uniquely shaped, with two lower wing-like lobes facing forward, and an additional lobe extended backwards and hooked into a spur. The flowers develop into pendant seed pods, which have projectile seeds that launch out of the ripe pods when they are touched. These ballistic seeds give the plant its ‘touch-me-not’ name.
The sweet joe-pye weed (Eupatorium purpureum) along the river had toothed leaves in whorls of 3, and tiny, dull pinkish-purple flowers in terminal, compound inflorescences. Although I didn’t see any butterflies while I was there, joe-pye weed flowers are typically very attractive to butterflies, as well as numerous other pollinators. Sweet joe-pye weed can thrive in shadier places than many other joe-pye weed species, and can be found in more woodland settings, such as the Fitch Conservation Area.
Finally, in a forest dominated by oaks and pines, cones from pitch pine (Pinus rigida) are a common sight on the forest floor. The cones are generally oval-shaped, approximately 2 to 2.5 inches long, and have prickles at the tips of each scale. These are easily distinguished from the cones of our other common pine, the white pine (Pinus strobus); white pine cones are slender, and approximately 3.5 to 6 inches long.
