Sorry for posting this in a couple of places
"The related Nigella sativa (and not N. damascena) is the source of the spice variously known as Nigella, Kalonji or Black Cumin."
Very confusing to say the least. Kalonji and black cumin are 2 different things.
Kalonji - black onion seed (in india)
Black cumin - kala jira (in india)
I Don't know which one is the right black seed.
In wikipedia, they show black onion seeds and the picture confirms the same. Black cumin seeds are thin and long.
Can you clear the confusion please ?
