The giant Rafflesiatuan-mudae - a fleshy red flower with white blister-like spots on its enormouspetals - came in at a whopping 111cm in diameter.
That's bigger thanthe previous record of 107cm on a bloom also found in the jungles of WestSumatra several years ago.
This is the largest Rafflesiatuan-mudae that has ever been documented, said Ade Putra at the AgamConservation Agency in Sumatra.
The flower's bloomwill only last about one week before it will wither and rot, he added.
It was namedRafflesia after British colonialist Sir Stamford Raffles who spotted one inIndonesia in the early 19th Century.
The species grows inseveral Southeast Asian countries, including the Philippines where a100cm specimen was recorded.
The parasitic bloom,sometimes referred to as corpse flower, mimics the stench of rotting meat toattract insects.
Sharing that noxioussmell is Indonesia's Amorphophallus titanum, a phallus-shaped flower that canreach heights of up to 3m./.
