I can certainly relate to this. I started scripting for very obtuse reasons, and quickly started seeing things everywhere which I could apply a little code to and improve my life.
You can have fun with 'em since they're public domain (:
Note 1: The metadata, such as title, author, etc. seem to be missing. If anyone knows of a collection with all that included, let me know (it's not in the EXIF either, I spot-checked).
EDIT: aha! Here is metadata, which you can correlate to the image files: https://github.com/Wumms/pomological
Note 2: I saw this in the MARC catalog record:
Use of the images in the U.S. Department of Agriculture Pomological
Watercolor Collection is not restricted, but a statement of attribution is
required. Please use the following attribution statement: "U.S. Department
of Agriculture Pomological Watercolor Collection. Rare and Special
Collections, National Agricultural Library, Beltsville, MD 20705"
This actually inspired me to go out and start (slowly) cataloging mostly historic 100+ yr old landscapes that were locked behind mostly non-US pay-to-access (cough British museums cough), and write a flurry of emails to institutions encouraging uploading high res versions. I'm contemplating a project to put historic paintings "on the map", depicting their geographically represented locations (when applicable), giving a window into the past. Maybe I should circle back on this effort to get more paintings released...
Ambiguity like this is way too common...
For another data point, this catalog.data.gov site[1] lists the license as "us-pd" (ie public domain in the USA). But then yeah, like you said the attribution demand is invalid.

Awesome work either way!

At this point, I've made my choice. I'm not going to look up the word. (I've lived more than 50 years, it's not likely to add much value for me now.) I'm not going to read the article. (It could only disappoint...)
I think less of parkerhiggins.net for tricking me with this article title. I think less of fanf2 for submitting this tricky article title. I resent even the time I've spent writing this. Bleah!
