Rafflesia lagascae
Definition
Rafflesia lagascae, locally called malabô, is a species of flowering plant in the parasitic genus Rafflesia, found only in the rainforests of Luzon in the Philippines. It grows wholly within its host vine of the genus Tetrastigma and has no stem, leaves, or roots, becoming visible only when its buds and flowers protrude through the host’s stem or roots.

Also Known As
Malabô (local name); Rafflesia panchoana is widely treated as a synonym of this species.
Examples and Analogies
Rafflesia species like this one carry the nickname “corpse flower” because their blooms imitate carrion, attracting the blowflies that pollinate them — a flower that behaves, ecologically, like a dead animal.
Usage Scenarios
R. lagascae appears in Luzon biodiversity inventories, university research on host–parasite specificity in Rafflesia, and community-based ecotourism during bloom seasons in Luzon forests.
Strategies
Because it depends entirely on its host vine, conservation targets the vine and the forest together: protecting watersheds, preventing vine cutting, and cataloguing persistent blooming populations rather than transplanting flowers, which cannot survive away from the host.
Security and Safety Measures
Guidelines at blooming sites include no touching of buds, no removal of plant material, controlled group sizes, and coordination with local environment offices, since over-visitation has killed buds at other Philippine Rafflesia sites.
Historical Context
The specific epithet commemorates the Spanish botanist Mariano Lagasca y Segura. The species belongs to the wave of Philippine Rafflesia documented from Luzon over the past two centuries, with R. panchoana (described in 2007) later subsumed under it by most authors.
Challenges and Controversies
Lumpers and splitters continue to debate whether populations called R. panchoana deserve species rank. As with all Luzon Rafflesia, habitat loss through logging and land conversion is the overriding threat.
