Someone is looking for sub-species designations? I still say that's a
squishy term. With a species as widely distributed as greensides you would
expect distinct population differentiation with characteristics like
coloration that have relatively simple genetics. But I'm still curious to
hear what this project comes up with, I'd even donate local greensides to
it.
