Distinctive “key” fruit, shaped to distribute seeds in the wind. Acer negundo “Ash-leaved Maple” or “Boxelder” • ID: It is a small, usually fairly short-lived tree that grows up to 10-20 m tall, with a trunk diameter of 30-50 cm, rarely up to 1 m diameter. The shoots are green, often with a whitish to pink or violet wax coating when young. It has pinnate leaves with usually five (sometimes three or seven) leaflets. Acer rubrum “Red maple” or “Swamp maple” Acer saccharinum “Silver maple” Betulaceae Alnus spp. • ID: alternate leaves, blunt ends, lenticels, cones and male catkins, gray branches • Habitat: near groundwater seeps, not found in bogs • Notes: very shade intolerant. Alders establish symbiotic relationships with nitrogen-fixing bacteria, that convert N2 into soilsoluble NO3. Cornaceae Red-osier Dogwood – Cornus stolonifera • ID: opposite, simple leaves with latex veins, red stems, green when young, lenticels • Habitat: streamsides, lakeshores, wetlands known for it propensity to form arching stolons • Notes: other red dogwood (C. amomum) has hairy twigs, and round lenticels in similar habitat • Relatives: flowering dogwood, bunchberry Cruciferae Watercress - Rorippa spp. • Fast-growing aquatic or semi-aquatic perennials native from Europe to central Asia • The stems of watercress are floating and the leaves are pinnately compound. • Relatives: Egyptian papyrus Sarraceniaceae Pitcher Plant - Sarracenia purpurea • ID: leaves shaped into a pitcher-like shape in which water accumulates • Habitat: sphagnum bogs and tamarack swamps, also fens and boggy interdunal flats and pools, surviving in both acid and alkaline habitats • Notes: invertebrates fall into accumulated, often cannot escape because of downwardpointed hairs on the inside of the plant. Some insects and mites live in the water, including the larvae of the nonbiting mosquito, Wyeomyia smithii Coq. (Diptera: Culicidae), which only is found in these plants.
