When I was a young, often at our dinner table was a vegetable we called Turnip. They were large, orange-yellow fleshed vegetable when cooked....with a distinctive taste

Now, when I shop at a supermarket, a turnip is a much smaller, lighter coloured vegetable with a milder (more watery, and bland) flavour with a yellow-whitish colour when cooked.
I have been told these are rutabbaga, or sweeds, not what I once knew as a turnip.

I suspect folks are getting terms, or different varieties (modern marketing hybrids) of the same vegetable mixed up. Anyone know?
Is the turnip I once knew been shelved for a new version, has it morphed, or, is my recollection faulty?
