### Step 1: Analyze the first option - Papaver somniferum and Morphine
- **Explanation**: Morphine is a natural opiate derived from opium, which is obtained from the dried latex of the unripened capsules of the poppy plant, scientifically known as Papaver somniferum.
- **Conclusion**: This pair is correctly matched.

### Step 2: Analyze the second option - Cannabis sativa and Marijuana
- **Explanation**: Marijuana is derived from the dried flowering tops of the Cannabis sativa plant.
- **Conclusion**: This pair is also correctly matched.

### Step 3: Analyze the third option - Erythroxylum coca and Cocaine
- **Explanation**: Cocaine is a natural stimulant that is obtained from the leaves of the Erythroxylum coca plant.
- **Conclusion**: This pair is correctly matched as well.

### Step 4: Analyze the fourth option - Atropa belladonna and Hashish
