San Fernando, Bukidnon, Philippines — Deep in the rainforests of Mindanao—where Philippine Eagles soar above ancient forests—scientists and Indigenous forest stewards have documented a remarkable botanical treasure: a new sub-population of Rafflesia schadenbergiana, the largest species of Rafflesia in the Philippines and among the largest flowers on Earth.
The discovery was made in the Mt. Sinayawan Range, within the ancestral domain of the Manobo Tigwahanon community of Barangay Kibongcog. The finding expands the known range of this critically endangered plant and highlights the global conservation importance of Indigenous-protected forests in Bukidnon.
Among the Tigwahanon, the extraordinary flower is called “Kuron to Busaw”—the Flower of the Mischievous Spirits. The name reflects local beliefs about mysterious forces that dwell in the forest, fitting for a plant that seems to appear suddenly from the forest floor.
For most of its life, Rafflesia remains hidden inside the tissues of a host vine called Tetrastigma. It has no leaves, stems, or roots. Instead, it lives entirely as a parasite within the vine until its enormous bud bursts open into a massive bloom that lasts only a few days.
When it flowers, Rafflesia schadenbergiana can reach nearly one meter in diameter—about the size of a small coffee table or a car tire. Its thick, reddish petals, speckled with pale spots, spread across the forest floor like a giant starfish before slowly collapsing after several days.
The newly documented site represents a distinct sub-population within the Mt. Sinayawan Range, separate from previously recorded occurrences. A broader distribution record of Rafflesia schadenbergiana in Bukidnon was documented in a 2024 publication in Sylvatrop, The Technical Journal of Philippine Ecosystems and Natural Resources, which highlighted the ecological importance of the region’s mountain forests as refuges for rare and endemic species.
The same Tigwahanon ancestral domain in Kibongkog is also rich in wildlife. Scientists have recorded at least 65 species of forest animals in the area, and 44 of these are found only in the Philippines. This makes the forest not only culturally important, but also globally significant for biodiversity.
University of Canterbury Professor and Botanist Dr Pieter Pelser, an expert on Philippine Rafflesia, emphasized the urgency of protecting the species:
“Rafflesia schadenbergiana is one of the Philippines’ rarest plants and is now critically endangered as tropical rainforests rapidly disappear. Its survival depends on protecting the last forest strongholds, and we honor the Indigenous communities who serve as guardians of the few remaining populations.”
Filipina botanist and taxonomist, Research Associate of University of Canterbury, and Rafflesia authority Julie Barcelona also welcomed the discovery and highlighted its scientific significance.
“Each new population of Rafflesia schadenbergiana reminds us how much biodiversity remains hidden in the Philippines’ forests. These remarkable plants survive only where ecosystems remain intact, making forest protection and Indigenous stewardship essential for their future.”
According to Andrei Von Tirona, senior author of the 2024 scientific paper documenting the Bukidnon record, the discovery highlights the importance of partnerships between scientists and Indigenous communities.
“The discovery of another sub-population of Rafflesia schadenbergiana in the Mt. Sinayawan Range shows that these forests still hold remarkable biological secrets. It also highlights how partnerships between scientists and Indigenous communities are essential for finding and protecting some of the rarest species on Earth.”
The discovery was made possible through collaboration with the Manobo Tigwahanon ancestral domain owners of Kibongkog, who serve as both Indigenous researchers and forest guardians.
Community leader and local co-researcher Lovermin Villasis explained the deep cultural meaning of the flower:
“For Tigwahanons, the forest is life. The elders taught us that when we care for the land, the land reveals its gifts. The Kuron to Busaw is one of those gifts—rare and sacred—reminding us that protecting our ancestral domain protects the living world within it.”
Recognizing the ecological importance of the site, the Barangay Local Government Unit of Kibongkog has declared the area a local conservation area. The Tigwahanon community is also working to manage their ancestral domain as an Indigenous and Community Conserved Area (ICCA), strengthening Indigenous leadership in biodiversity conservation.
The forests of the Mt. Sinayawan Range are proving to be an extraordinary refuge for wildlife. The same landscape has recently been documented as home to two newly discovered pairs of the critically endangered Philippine Eagle, further underscoring the global ecological significance of the area.
San Fernando Mayor Rogelio Yeke welcomed the discovery and praised the leadership of the Tigwahanon community:
“This discovery highlights the extraordinary natural heritage of San Fernando. We commend the Tigwahanon community of Barangay Kibongkog for protecting their forests, and the municipal government will continue supporting efforts to conserve these ecosystems for future generations.”
For scientists and Indigenous partners alike, the emergence of Kuron to Busaw carries a powerful message: some of the world’s rarest species still survive where Indigenous communities continue to defend their ancestral lands.
Mr. Dennis Salvador, Executive Director of the Philippine Eagle Foundation, reflected on the deeper meaning of the discovery:
“It is a profound honor for the Philippine Eagle Foundation to help bring this remarkable flower to science alongside our Tigwahanon Indigenous partners. To the Tigwahanon of San Fernando, the Kuron to Busaw grows in forests that are sacred and alive with spirits. To science, the same forests are places where evolution continues to shape rare and extraordinary life."
This discovery reminds us that the forest can be understood in many ways—and when Indigenous wisdom and scientific exploration walk together, we begin to see its deeper truths.”

This discovery is fascinating! ragdoll playground I recently hiked in a similar rainforest, and the biodiversity was mind-blowing. Can't wait to see how this impacts conservation efforts for the Philippine Eagle!
Wow, this discovery of the giant Rafflesia in the Philippine Eagle forests is absolutely fascinating! It’s amazing how nature keeps surprising us with these hidden wonders, especially inside places that are already protecting such majestic creatures. Reading about the “flower of the mischievous spirits” makes me want to visit the Bukidnon forests and see one in person someday. Honestly, when I find myself lost in random nature blogs like this during a dull lecture, I remember it’s one of my favorite things to do when bored in class—scrolling through stories that connect science, mystery, and conservation. It’s inspiring to see how the Philippine Eagle Foundation not only preserves wildlife but also uncovers new life forms that remind us of how…
I never really thought about how a single flower could carry so many layers of meaning—cultural, ecological, and even spiritual. Discovering a new sub‑population of Rafflesia schadenbergiana in the Tigwahanon forests feels like stumbling on a hidden story that’s been quietly unfolding for centuries. I recently found https://7bitcasino.com/ while reading about how different worlds think of “rare treasures,” and it reminded me that what feels magical in nature can also spark curiosity in completely different spaces. For me, it’s fascinating to see how Indigenous knowledge and scientific research come together around something as extraordinary as the Kuron to Busaw.
Wow, what an incredible discovery! The "Flower of the Mischievous Spirits" sounds like a mythical treasure straight out of Philippine folklore, blooming in the Philippine Eagle forests. Kudos to the team for spotlighting this giant Rafflesia—hoping it inspires more conservation efforts! ~ Names Review
This discovery is absolutely fascinating! The Rafflesia has always been such a mysterious and rare flower, and it’s amazing to see it thriving in the same forests that protect the majestic Philippine eagle. It really shows how interconnected nature is—preserving one species can also safeguard countless others. Reading this makes me think about how delicate balance and protection are, whether it’s in environmental conservation or in academic work where every detail matters. I recently stumbled upon similar dedication while searching for Help with Law Assignment UK services, and it reminded me that true growth—whether in learning or in nature—comes from patience and respect for the process. Huge credit to the Philippine Eagle Foundation team for their inspiring work!
