ID This - A Correct Quiz Answer
Some of the guesses included Boehmeria cylindrica, Urtica dioica (or maybe Laportea canadensis), and Pilea pumila. None of these were correct, but what do they all have in common? They are all in the family Urticaceae. When I first saw this plant, I was convinced it was in the family Urticaceae, but nothing fit. As I was about to give up until I could see a more mature specimen, I thought... man, those leaves look like mulberry. Then it hit me that there was an herbaceous, non-native mulberry that I had never seen. I looked up Fatoua villosa, Mulberry Weed, and sure enough, it was a perfect fit. Interestingly, this species was once known as Urtica villosa.
This is Fatoua villosa, Mulberry Weed, or Hairy Crabweed (Moraceae). It was introduced in the United States from east Asia as recently as the 1960s. First found in Louisiana, it has rapidly spread throughout the southeastern United States, pushing north into Indiana and Ohio; it has also been recorded in California and Washington. Much of its spread has been attributed to the horticultural trade, where it persists as a weed in greenhouses.
In many of the northern locations for this plant, it has been found more commonly inside greenhouses. Only very recently (1991 in Ohio) has this species been observed outside of greenhouses in the northern extent of its range.
Mulberry weed is an annual that continuously produces an abundance of seeds from the time it is a very small plant until it reaches a maximum height of up to 80 cm. When mature, the seeds are "explosively expelled," according to Flora of North America.
Watch for this weed around greenhouses, in waste areas, and in disturbed sites as it continues its northward expansion.
Congratulations, Justin and Susan, for correctly identifying the plant in this plant quiz.

The land of flowers 2
In the dry prairie at Myakka River State Park.
In the dry prairie with blueberries at Myakka River State Park.
This flower was growing profusely throughout cattle pastures and along roadsides.
I did not see many individuals of this flower blooming yet.
This 'weed' was growing very commonly in sandy margins of ag fields in Manatee County.
Growing very weedy in a disturbed site in Hillsborough County. I thought it was a Corydalis at first.

Northern Indiana Update
Some flowers of Acer saccharinum are perfect, but others are fully pistillate (like those above) or fully staminate (like some of those shown below).

The land of flowers
It is very cool to find out that there are other pawpaws out there in the world.
This native is so prolific that it seems like an invasive. The flowers are gorgeous.

Numerous Plant Quizzes - Annotated Photo

I've labeled the plants that I was able to ID from the photo and my memory of the site. You'll probably need to click on the photo to expand it to see the answers and the plants they are denoting. The key to the answers is below...
A – Solidago graminifolia v. nuttallii (Euthamia graminifolia)
B – Scirpus pungens (Schoenoplectus pungens)
C – Pycnanthemum virginianum
D – Eupatorium maculatum (Eupatoriadelphus maculatus)
E – Potentilla fruticosa (Dasiphora fruticosa)
F – Lysimachia quadriflora
G – Dryopteris thelypteris v. pubescens (Thelypteris palustris v. pubescens)
H – Rosa palustris?
I – Juncus dudleyi
J – Calamagrostis canadensis?
K – Eupatorium perfoliatum
L – Aster novae-angliae
M – Solidago riddellii (Oligoneuron riddellii)
N – Carex sterilis
O – Typha sp.
I don't see Onoclea sensibilis, Carex brunnescens (maybe this was guessed for Carex sterilis?), or Rudbeckia hirta (maybe this was guessed for the yellow composite in the background, which I think may be a Helianthus?), which were all suggested.
Pretty sharp group we have here! There were very few plants that I was able to identify from the photo and my memory of the site that were not identified by the group. Thanks for all of your comments.

Name That Plant - An Answer
Here is the uncropped image of this plant...
This is Solidago uliginosa (Bog Goldenrod), growing amongst Equisetum arvense, Aster umbellatus, Calamagrostis canadensis, Rubus pubescens, Polygonum sagittatum, and others. Justin suggested the possibility of Solidago speciosa, which as he noted grows in drier conditions. Solidago uliginosa has thicker textured leaves that have a longer length to width ratio than those of S. speciosa. The lower leaves of S. uliginosa are somewhat clasping the stem, but this character isn't obvious in the quiz photo.
Solidago uliginosa is a polymorphic species of eastern North America, where it grows in bogs, marshes, and wet woods (Semple & Cook 2006). These photographs were taken on August 18, 2009 in Superior, Wisconsin. Plants of this species that we saw in Wisconsin look somewhat different from those that I typically see in Indiana. In fact, the first time I saw it, I had to ask our local expert which Solidago it was. Individuals of this species that I see in northern Indiana have fewer stem leaves and inflorescences that are less dense.
Solidago is from the Latin solido, meaning “to make whole or heal,” a reference to the medicinal qualities of the genus; the specific epithet uliginosa means “of marshes (Wisplants 2010).
