Upland southern edge of field b
Panzner b in 30cm water with thick lemna and water meal. Couldn't reach many specimens and hard to get a good photo. I think it would be common bladderwort but need to get it to a key to check
Panzner field b. common in patches

Panzner Wetland Field E in restored emergent wetland (SE corner, only one I saw). This keys out to either lupuliniformis or or lupulina, but am not sure whether the edges on the aches have a prominent enough knob to be the former. I included a second photo with a closeup (iphone through microscope eyepiece) of an achene, hoping someone with more experience can tell which.
My impression of the plant in the field was that it looked different than the Lupulina I've seen before - perigynia point more forward, I think, coarser.
Panzner Field B at ground level. Uncooperative seedling prevents a good view of the eyes, but didn't want to disturb him
In Field B (emergent wetland), on Typha at eye level
