How to tell oak from walnut flooring

Question

How do I identify what kind of hardwood flooring this is by the grain?

that is not walnut and almost surely oak. Walnut grains are way way more subtle and wavy. — DMoore, Commented Nov 8, 2021 at 17:00
99% certain that's oak. Are you doing a patch job or a repair? If so then you'll need to figure out whether it's red or white oak. — MonkeyZeus, Commented Nov 8, 2021 at 18:08
Something to think about: Identifying wood from a picture is difficult enough that it's considered off-topic at Woodworking. — FreeMan, Commented Nov 8, 2021 at 18:18
For what it’s worth, the diagonal ray fleck is classic quartersawn oak. (Ray fleck occurs in other species, though usually to a lesser degree.) — Aloysius Defenestrate, Commented Nov 9, 2021 at 23:29

For solid hardwood, oak is by far the most common in the US. Engineered hardwood has more variety since only a sliver of wood is needed - many more varieties become affordable.
