I collected seeds of a local pine tree, and the seeds were different from typical pine seeds I've seen before. It has a little needle sticking from the end of it. The tail is stiffer and doesn't break as easily. The seed as a whole is about 2 inches.
This tree was growing in San Diego.
Here's a picture of it's leaves.
The tree was a mature tree. Not tall and conical, but rather had medium height (20-30 feet) and a dome shaped canopy.
Update: As @blacksmith37 noted in the accepted answer below, this wasn't actually a pine. It was some sort of mesquite tree. These seeds did travel quite a bit.
