There are still open fields and some woodland behind many of the strip malls and gas stations lining Highway 27 through Cold Spring, Kentucky. Since I was running errands in the area, I took 20 minutes to see what interesting fall flowers and pollinators might be making their homes nearby.
This was a rare sighting -- a clearwing moth at rest. I saw what looked like a bumble bee buzzing along the edge of the field, and when it lit on some goldenrod foliage, I took a closer look. Not a bee, but a clever mimic. It rested there for a little while and then flew on.
I see these moths pretty commonly at this time of year, but I've never seen one land on something before.

1000’s of plants at this truly bizarre site. The Silphium seems to be all that is left of what must have been a large prairie, which was gouged and bisected by Rt. 19 in the last ~25 years. There are scattered native species accompanying it, but aside from the junipers, the most abundant here is non-native and invasive species. Although the parts of Bracken County that are not wetland and river-adjacent are under-botanized, it is a bit mind boggling that this population (and the natural community that went with it) went unnoticed by collectors in the past.

? Seems too hairy on the calyx mouth and flower for this species, but not sure

Notocactus laetivirens [synonym under Parodia = Parodia muricata]
Notocactus laetivirens is most unusual, in that along its roots it distantly forms underground nodules that eventually emerge as new individuals. No doubt this is a marvelous way of surviving damage to the mother plant, whether that damage be by adverse weather or physical mishap such as trampling.
This individual was grown from seed sourced from Mesa Garden (some years ago).

Magnificent specimen! I wonder how old it is? Given Transylvania University's history with C. S. Rafinesque, I'm curious if it may be descended from some of his first collections of the species in 1822.

It struck me as smaller, and strictly adnate as compared with Porella platyphylla.
On a north-facing vertical bedrock exposure above a woodland stream.
The leaves are half the size (0.5 mm) of Porella platyphylla (1.0 mm).

2005, Northern Kentucky University's Costa Rican Natural History course. We spent an hour or two at Volcan Poas, hiking up the main trail to see the crater lake. There were many melastomes along the way.

This individual was found in mucky organic soil at the edge of a small, spring-fed rivulet, which was running along the outer edge of a graminoid-dominated bog. The last photo is the best habitat shot I have, unfortunately. The small rivulet runs along the base of/somewhat undercuts the bluff, and thus is not super visible in the photo. The plant was collected near where the grassy edge of the bog and the edge of the rivulet meet, more or less directly in front of where the person in the photo is standing.
Ruler units are 0.5 mm.

Here is an additional observation of the same individual, with more close-up photos of the plant taken in the field.

Compared with pressed N. trifoliolatus and alba specimens. Pappus color seems to lean toward trifoliolatus, but could be convinced.
Found near top of Shellhouse Mtn, a dry chestnut oak woodland.

Very weird morphology…found on this individual and several others nearby.
