I am a parasitic plant with no chlorophyll. I am known for my large, fleshy flower, which emits a foul odor to attract pollinators. I do not have any leaves, stems, or roots. What am I?

1. I am found in Southeast Asia.
2. My flower can be up to 3 feet in diameter.
3. I am sometimes called a 'corpse flower'.
4. I obtain all my nutrients from a host vine.
