Safety Overview
1.Canarium — Overview
Canarium strictum, colloquially known as black dammar, is a magnificent evergreen tree belonging to the Burseraceae family, deeply rooted in the tropical and subtropical regions of South and Southeast Asia. Its natural range extends across India, Bangladesh, Myanmar, Thailand, and into southern China, where it thrives as a dominant species within its forest ecosystems. This commanding tree frequently reaches impressive heights of 20 to 30 meters, with some mature specimens soaring up to 50 meters, establishing a prominent presence in the canopy.
The trunk, or bole, of Canarium strictum is characteristically straight and cylindrical, often achieving diameters of up to 80 centimeters. It is encased in a distinctive greyish-brown bark that, as the tree ages, develops fissures and exfoliates, revealing lighter inner bark patches that contribute to its unique aesthetic and serve as a visual identifier.
The foliage of Canarium strictum is arranged alternately along robust branches, forming elegant pinnate leaves. Each compound leaf is composed of approximately 5 to 11 individual leaflets, typically ovate to elliptic in shape, measuring between 6 and 10 centimeters in length. The leaflets exhibit a striking contrast, presenting a glossy, dark green upper surface and a noticeably paler, often glaucous, underside.
Their margins are typically entire, and the venation is prominent, creating a subtly textured appearance. The tree's reproductive structures are small, delicate white to cream-colored flowers, each about 5-6 millimeters in diameter. These blossoms are borne in branched axillary or terminal inflorescences (panicles) and emit a subtle yet distinct, sweet fragrance.
This aroma is crucial for attracting a diverse array of insect pollinators, essential for the tree's successful reproductive cycle and genetic propagation. Ecologically, Canarium strictum demonstrates remarkable adaptability and resilience, flourishing in humid, well-drained forest environments, particularly in evergreen forests at elevations up to 1,500 meters.
