Plant & Global: Rafflesia Flower (Endangered)

Background Information:

  • -Native of rainforests of Sumatra & Borneo in the Indonesian Archipelago
  • -Largest flower in the world
  • - Parasitic plant without any leaves, stems, and roots. It attaches itself to a host plant.
  • -Nutrient-absorbing threads to absorb nutrients from the host on which it lies on.
  • -DO NOT have chlorophyll and CANNOT undergo photosynthesis
  • -Forest mammals & tree shrews feed on the Rafflesia fruit - hard coated seeds (15 cm diameter)
  • -"Stinking Corpse Lily" - rotten smell is from reddish tentacle-like threads branched inside the petals
  • -Sensitive & only bloom for less than a week.

Threats/Causes of Endangerment:

  • - Illegal collectors- people steal to us as remedy, in Southeast Asia, for internal injuries & infertility. Sell at high prices
  • -High Mortality Level- Small percentage of flowers will bloom per year & only last a few days
  • -Habitat Specialization: Rafflesia can only parasite some particular species, which makes it harder for them to survive
  • -Sex Ration Disproportion- male plants are more widespread then females & can diminish their chance for the partners to bloom and be close enough at the same time for pollination
  • -Habitat destruction

Possible Course of Action for Protection:

  • -Preserve the Rafflesia Habitat
  • -National Parks have asked indigenous people to monitor the buds & prevent people from stealing them
  • -Conservation Programs
  • -Reduce Habitat Destruction (reduce rainforest clearing)
