[MAIPC] mystery invasive in central NJ

[Stephen Hiltner]

Many on these listserves can be grateful that you haven't encountered
Photinia villosa. I believe it is an escape from a nursery in Princeton,
NJ, and is now spreading across the state. A few years back, I discovered
another invasive small tree that may be in the same genus, which was
changed from Photinia to Pourthiaea. Here are a couple photos of the
foliage, comparing the two: https://photos.app.goo.gl/gptnqGTfHnVXZuNz9 The
Photinia villosa is much coarser.

I posted more photos
<https://www.princetonnaturenotes.org/2022/01/a-mystery-tree-in-princeton.html>
on my nature blog, and the species, whatever it is, is now being discussed
on iNaturalist: https://www.inaturalist.org/observations/117251042

I've been encountering more and more in Princeton preserves. Most are small
and don't bloom, but I have one in my yard that gets some sun and just
finished blooming.
