Botany picture #70: Thlaspi arvense
Thlaspi arvense (Brassicaceae), Germany, 2012. This I found one of the easiest Brassicaceae that I had to learn in the first year botany course in university. The fruits are very characteristic, and it is a fairly common weed of building sites and agricultural fields.
