A long, dry flower bract of a Tilia americana, or perhaps a cordata.
Median of Callery Pears
Pyrus calleryanas on a median IDed by thick, scaly bark and petiolate, ovate, glossy leaves with (slightly) wavy margins.
Common Serviceberry
[Revisited] Amelanchier arborea IDed by off-green, oval leaves with tapered tips, finely serrate margins, and mildly pubescent undersides; clusters of drooping white flowers
Willow Oaks
Two Quercus phelloses IDed by noticing the two were the same species and using observations from each. The features include: two lanceolate, willow-esque leaves persisting through winter and into spring; smooth, gray bark of young willow oaks in the midst of transitioning into rough and irregular furrows; slender, hairless twig. The buds are supposed to be very small, reddish brown, and sharp pointed according to this website. These buds don’t match the small bud requirement. But given that the leaves are starting to sprout, the unusually long buds may just be the leaves distorting the normal bud shape.
Black Locust
Robinia pseudoacacia IDed by thin, dry, dark brown, multi-seed legumes (on most trees, 5-10 cm long); deeply furrowed, rough, gray bark; irregular crown shape with upward branching. There should have been small thorns on the twigs and branches but I didn’t bother to look. Inaccurate post date.
Eastern White Pine
Pinus stronus IDed by the tag on the tree. Also the five needle fascicles.
London Plane Trees
A bunch of random photos of Platanus × acerifolia taken over the winter of 2021-2022. IDed by off-white mottled bark. Very easy to identify from a distance.
Japanese Cherry
Prunus serrulata IDed as a cherry by the cherry-esque shiny bark with lenticels, and as a Japanese cherry by the pink flowers and gray bark. My best guess at the variety would be kawazu sakura, since the flowers were in full bloom early April, but Japanese cherry varieties are always a little sketchy and I’m very bad at IDing them.

A few other acer rubrums also IDed by flowers and bark. Inaccurate post date
