Magkono
Definition
Magkono (Xanthostemon verdugonianus), also called Philippine ironwood, is a small to medium tree endemic to parts of the southern and central Philippines, including Dinagat and adjacent Surigao areas, famed for producing one of the hardest and densest woods in the world. Its extremely slow growth and limited distribution make natural stands precious, and its dark, fine-grained timber sinks in water when seasoned.

Also Known As
Philippine ironwood; Xanthostemon verdugonianus; mangkono; magkono tree.
Examples and Analogies
Working magkono is like working stone that happens to grow: ordinary nails bend against it, and blades dull rapidly. Its density makes a piece of seasoned wood behave like a metal bar, sinking in water rather than floating like typical lumber.
Usage Scenarios
Historically used for tool handles, posts, anchors, and bearings in harsh service, it now features in specialty crafts, scientific collections, and species-conservation discussions. Ecotourism materials from Dinagat and Surigao present it as a botanical emblem.
Strategies
Because harvesting cannot be sustained from wild stands, strategies center on ex situ propagation, protection of known populations, and research into its growth requirements. Woodworkers reserve legal stock for small high-value items.
Security and Safety Measures
As a threatened endemic it falls under wildlife-protection rules, and mineral-rich Dinagat’s mining tenements make habitat oversight critical. Preserving standing trees safeguards the thin soils of ultramafic areas where few other species thrive.
Historical Context
Described by nineteenth-century botanists from Philippine material, magkono entered the literature as a botanical curiosity of hardness. Twentieth-century logging and, later, mining on Dinagat concentrated attention on its restricted habitat, making it a flagship for the conservation of Philippine ultramafic flora.
Challenges and Controversies
Mining concessions overlapping its habitat pit livelihoods against conservation, and its slow growth frustrates both plantation attempts and quick restoration promises. Verifying legally sourced wood is difficult, complicating craft trade.
