The source of morphine is the opium poppy, known by its botanical name as papaver somniferum. what does this mean in english?

Papaver means that it is a member of the Poppy genus when translated to English, while somniferum means "sleep-inducing". When translated from Latin to English, it basically means "the poppy that brings you sleep" or the "sleep inducing poppy", which is not that wrong considering that it is used to make opium.
