World’s largest rare flower sighted in Sierra Madre

A GOVERNMENT staff reported sighting a Rafflesia manillana, the world’s largest flower, in the forests of a northern Philippine mountain range.

I was speechless when I saw its beauty, said Forester Max Millan Jr., a field personnel of the Department of Environment and Natural Resources (DENR) Region 3 (Central Luzon) office.

Millan was with a team of biologists from the National Museum of the Philippines in the Sierra Madre mountain range, Aurora province, when he spotted the rafflesia.

Led by mycologist Edwin Tadiosa, the national museum team was conducting a routine biological survey, according to Millan.

The team was surveying reptiles and amphibians inside the 5,000-hectare Aurora Memorial National Park.

“The flower is in full bloom, with a diameter of 17 centimeters,” Millan said.

Found only in the Philippines, the parasitic plant Rafflesia manillana is already in the DENR’s list of threatened species, according to Millan’s boss Maximo Dichoso.

“The presence of this flower only proves the rich biodiversity in Aurora’s forests,” Dichoso, executive director of the DENR Region 3 office, said.

Protected Areas and Wildlife Bureau Director Theresa Mundita Lim added that the discovery affirms the recognition given to the Philippines as a “mega-diverse country” not just for animals but for plant species, as well.

“We are now the country with most number of rafflesia species more than other Asian countries,” she said.

this is a flower?  (though i won't question biologists, taxonomists, and foresters.)


Rafflesia (Rafflesia manillana)

Description

The dramatic Rafflesia flowers are the largest single flowers in the world; the leathery petals can reach over 90 centimetres across. Rafflesia is a parasite that depends completely upon its host; the majority of the plant’s tissues exist as thread-like strands entirely within the host’s cells. These host plants are vines of Tetrastigma spp., and the Rafflesia plant is itself not visible until the reproduction stage when flowers first bud through the woody vine and then open into the magnificent spectacle that is world-renowned today. The flowers can take up to ten months to develop from the first visible bud to the open bloom, which may last no more than a few days.

Currently 17 species of Rafflesia are recognised and these mainly differ in the morphology of their flowers. In general however, the flowers consist of five leathery petals that are orange in colour and mottled with cream-coloured warts. There is a deep well in the centre of the flower containing a central raised disc that supports many vertical spines. The sexual organs are located beneath the rim of the disk, and male and female flowers are separate.

another claimant:

Rafflesia arnoldii found in indonesia





The flower with the world's largest bloom is the Rafflesia arnoldii. This rare flower is found in the rainforests of Indonesia. It can grow to be 3 feet across and weigh up to 15 pounds! It is a parasitic plant, with no visible leaves, roots, or stem. It attaches itself to a host plant to obtain water and nutrients. When in bloom, the Rafflesia emits a repulsive odor, similar to that of rotting meat. This odor attracts insects that pollinate the plant.

tale of the, uh, tape and weighing scale:

Rafflesia arnoldii - 100 centimeters (39 inches) in diameter, and weigh up to 10 kilograms (22 pounds)

Rafflesia manillana - petals can reach 90 centimeters (35.43 inches) across, (no weight given)

one website claims that this is the smallest of all the Rafflesia flowers, which may be an erroneous claim because the smallest is Rafflesia baletei, which is 12 centimeters (4.72 inches) in diameter

Another enormous flower found in Indonesia is the Amorphophallus titanum, or Titan arum.

 

Technically, the Titan arum is not a single flower. It is a cluster of many tiny flowers, called an inflorescence. The Titan arum has the largest unbranched inflorescence of all flowering plants. The plant can reach heights of 7 to 12 feet and weigh as much as 170 pounds.

thus:

Rafflesia is the largest individual flower. Titan arum bears the largest inflorescence.
