Toog
Also known as: Petersianthus quadrialatus (scientific name) · Philippine rosewood (commercial usage, loose) · Komis (regional name usage)
Definition
Toog (Petersianthus quadrialatus) is a giant rainforest tree of the Philippines and one of the tallest flowering trees in the country, capable of exceeding 60 meters. Belonging to the family Lecythidaceae, it is best known from Agusan del Sur in Mindanao, where a famous century-old specimen in San Francisco was declared the Philippine Centennial Tree in 1998.

Examples and Analogies
Among Philippine trees the toog is what the giant sequoia is to North America: a skyline-dominating emergent whose exceptional height makes single trees into landmarks, tourist draws, and conservation symbols for the forests that once covered the Agusan River basin.
Usage Scenarios
Municipal tourism offices bring visitors to the Centennial Tree site in San Francisco, Agusan del Sur; foresters assess remaining mature toog stands in lowland rainforest; and wood-sector stakeholders discuss the species in the context of timber regulation and reforestation with native species.
Strategies
Conservation strategies protect known large trees as natural monuments, include toog in native-species reforestation for the Agusan floodplain, and use the Centennial Tree’s fame to anchor local environmental education.
Security and Safety Measures
Cutting naturally growing toog is restricted by forestry rules and requires permits; heritage trees like the Centennial Tree are shielded by local ordinances; and visitors to the site should follow municipal guidance to avoid damaging the root zone of a fragile giant.
Historical Context
The toog gained national fame when the specimen in San Francisco, estimated to be well over a century old and about 65 meters tall, was honored during the Philippine centennial of independence in 1998, turning a lowland Mindanao timber species into a widely cited emblem of the country’s remaining old-growth wealth.
Challenges and Controversies
Lowland rainforest conversion to agriculture has made tall toog rare outside scattered remnants; confusion with commercially marketed “Philippine rosewood” names complicates trade discussions; and debates continue over how best to protect landmark trees on private land through incentives rather than prohibition alone.
