Information about Rafflesia (Rafflesia kerrii)
in Khao Sok National Park

​

Scientific Name: Rafflesia kerrii

Local Name: Dok Bua Phut (Giant Rafflesia)
Family: Rafflesiaceae

​

Name Origin:

The Rafflesia kerrii was named in honor of Sir Hugh Kerr, a British botanist who discovered this species in Thailand. The genus name "Rafflesia" comes from Sir Stamford Raffles, the founder of Singapore, who was one of the first to discover this flower in Sumatra in 1818.

​

Botanical Characteristics:

Rafflesia kerrii is a flowering plant that lacks the usual structures like leaves, stems, or roots. Instead, it consists of a large flower that is red or orange in color, with white mottled patterns on the petal edges. The flower has a diameter of about 50-90 centimeters and can weigh up to 10 kilograms. Rafflesia kerrii is a parasitic plant that relies on nutrients from the vines of the Tetrastigma plant by forming a network of haustoria (parasitic roots) that penetrate the host plant's vascular system.

​

Pollination:

Rafflesia kerrii uses a scent similar to rotting flesh to attract flies, which act as pollinators. These flies enter the central part of the flower in search of food, and as they move around inside the flower, they collect pollen from the male flower and transfer it to the female flower. This pollination process is complex and has a low success rate due to the requirement for both male and female flowers to bloom simultaneously.

​

Blooming Season:

Rafflesia kerrii typically blooms during the winter season, from November to February, when the weather is cool and humid, ideal for the growth of this flower. However, the flower blooms for only a few days before it starts to wither. Finding a fully bloomed Rafflesia is challenging and requires a bit of luck.

​

Conservation and Biological Importance:

Rafflesia kerrii is a plant of high biological significance due to its rarity and risk of extinction. Its dependence on a single host plant species and specific environmental conditions makes its propagation and conservation difficult. Additionally, habitat destruction from deforestation and unsustainable tourism are major factors contributing to the decline in Rafflesia populations.

​

Habitat in Khao Sok National Park:

Khao Sok National Park is one of the few places in Thailand where Rafflesia kerrii can be found due to its suitable environment, including high humidity, appropriate temperature, and the abundance of Tetrastigma vines. Rafflesia can usually be found along trekking routes that are at a higher elevation and away from the main tourist areas. Planning and careful travel are necessary to view Rafflesia in bloom.

​

Local Beliefs and Legends:

Locally, there is a belief that Rafflesia is a sacred flower inhabited by spirits. Some villagers believe that damaging or disturbing the flower will bring bad luck. This belief helps in the conservation and respect for the natural habitat of this rare flower.
