Introduction:
The corpse flower, scientifically known as Amorphophallus titanum, has captivated audiences worldwide with its unique characteristics. Native to Sumatra, this flower attracts attention not only for its size but also for its pungent odour reminiscent of decaying flesh. The recent bloom of a specimen named Putricia at the Royal Botanic Gardens in Sydney has drawn over 20,000 visitors. This flower last bloomed in 2010, making its current display a rare event.
Description and Naming
- The corpse flower gets its name from the Indonesian phrase Bunga bangkai, meaning “corpse flower.”
- Its species name translates to “titanic misshaped penis” in Ancient Greek, denoting its unusual shape.
- The plant can grow up to 3 meters tall and features a spadix that emits foul odours to attract carrion insects for pollination.
Blooming Cycle
- Corpse flowers have an erratic blooming cycle, often flowering only once every decade.
- The blooming process is dependent on the energy stored in the corm, a bulb-like structure underground.
- The plant goes through several leaf stages to photosynthesise and build energy reserves before it can bloom.
- The bloom itself lasts for just one day, with the spathe unfurling over several hours.
Pollination Mechanism
Pollination is a delicate process for corpse flowers. They possess both male and female flowers, with females opening first to prevent self-pollination. Successful reproduction requires the simultaneous blooming of nearby flowers. This rarity in blooming poses a challenge for the survival of the species in the wild.
Chemical Composition of the Odour
Research has identified several chemicals responsible for the corpse flower’s distinctive smell. These include:
- Dimethyl disulfide (garlic-like scent)
- Dimethyl trisulfide (reminiscent of rotting meat)
- 3-Methylbutanal (smells like soft cheese)
- Dimethyl sulfide and Methanethiol (similar to boiled cabbage)
- Methyl thioacetate (sulfurous odour)
- Isovaleric acid (similar to smelly feet)
Conservation Status
The population of corpse flowers in the wild has declined due to habitat loss and poaching. Estimates suggest only about 300 remain in their natural habitat, while around 1,000 exist in cultivated settings. Conservation efforts are crucial to ensure their survival.
Viewing Opportunities
Many botanical gardens globally cultivate these plants. Greenhouses are ideal for these tropical species, providing the humid conditions they require. Gardens in the US, Canada, Brazil, Europe, China, and Africa have hosted successful viewing events.
