Welcome Laurin. Phil's right, many brassicas look the same. I have a certain Chinese green (not sure what it's called) that has leaves like that, the leaves of radish and daikon tend to be a bit more "indented" than that. It looks like you've got multiple plants-- you might consider pulling the one that is putting up flowers, unless you want the seeds, to see what it's got underneath.
I'm also southern hemisphere and all of these plants are bolting early for me this year (normally we'd be quite cold but so far this year it's been very hot, only now are we getting some cold at night. i planted peas and they just laughed at me, didn't even come up. maybe next month.....)
As Phil says, if they're very peppery you might want to cook them or use them in a quick pickle. I often just chop up greens like this, sprinkle some salt, let them sit and then squeeze them out, serve with a bit of sesame oil alongside a meal.
