Answer:

Utricularia vulgaris
Hamm, this is a bladderwort, most probably great bladderwort (its more recent Latin name is Utricularia macrorhiza). The resolution is low, and there are many bladderwort species around here, but I rely on yellow flowers (U. purpurea would be purple), the floating habit (another common yellow-flowered bladderwort, U. cornuta, would be rooted in the shore mud or sand), the absence of the floating device (such as in U. inflata or U. radiata), and also the fact that other yellow bladderworts are more rare. I am talking about the plant in the center. The one surrounding it is white water lily (Nymphaea odorata).

Answer:

Juniperus horizontalis
Bill, it looks like some non-native juniper that escaped from plantings, maybe creeping juniper. Because of low resolution, it's hard to tell. I can also be some false Cyperess (Chamaecyparis). Do you have coordinates for the spot by any chance? We'd go take a look.

Answer:

Vitis riparia
This is a grape, which seems to be riverbank grape. There are 3 native grapes in Massachusetts: fox, summer, and riverbank grape. The latter is native in western and central MA including Hampden Co. (where Southwick belongs), reaching east to Middlesex and Essex.

Vitis riparia
I decided this is riverbank grape, because I noticed pointed teeth on most leaves. Each tooth is somewhat asymmetric, with one side concave, which is a diagnostic character for this grape. The one leaf that you showed close-up is more lobed and not typical for this clone. There is always variation with grape leaves, but we should consider the "average" leaf when it comes to ID. Did you take your photos at some stream bank?

Answer:

Bidens tripartita
This is beggarticks, most probably a non-native species, leafy-bracted beggartics, which was formerly called Bidens comosa and now B. tripartita. It is widespread in MA, except for the southeast (excluding Bristol, Plymouth County, and the Cape).

Datura stramonium
Sorry, I've been wrong! I looked at the fruit more closely and now realize that this is poisonous Jimson-weed.
