I was at Singapore Botanic Gardens today 27 Nov 2010 with L, and witnessed this – Amorphophallus Titanum. Dr L told us about it this morning at breakfast.
The fragrance of the inflorescence smells of rotting meat. Sounds like the raffleasia? Well there's no smell yet. Apparently, the plant has both male and female flowers. The female flowers first and dies, then the male flower opens. This is nature's way of preventing self-pollination. Brilliant! I hope to capture it when it fully opens. Look at how tall it is, 3 person's height!
