Scientific Summary

GBIF Taxonomic Backbone & Wikipedia Registry Profile

Tree to 12 m tall; young twigs glabrous. Leaves: petiole 2.5 - 20 (- 30) mm long, glabrous; blade narrowly elliptical to elliptical (oblanceolate to oblong-oblanceolate, obovate), (5.5 -) 7 - 15 (- 17) × (1.5 -) 2.1 - 6 (- 6.9) cm; base cuneate to attenuate or convex, usually attenuate at extreme base; margins crenate-serrulate (subentire, crenate-serrate or crenulate), often slightly revolute; apex rounded to acute or cuspidate (shallowly emarginate, short-acuminate). Inflorescences spicate with a thick rachis, 1.4 - 7 cm long, canescent; flowers in elongated manyflowered clusters, sessile; bracts transversely (to very broadly) oblong, deltoid or ovate, often irregular; bracteoles reduced to minute teeth, caducous. Flowers (6 -) 7 (- 8) - merous, white or greenish; sepals ovate to oblong or broadly ovate-deltoid, 0.2 - 0.3 (- 0.4) mm long; petals broadly (transversely) oblongelliptical to oblong-ovate, (0.4 -) 0.5 - 0.8 mm long, glabrous (pubescent abaxially but not ciliate), apex rounded; filaments 0.1 - 0.4 (- 0.5) mm long; upper surface of ovary densely shorttomentose; styles (2 -) 3, 0.1 - 0.4 mm long.
Biology & Conservation

Ecologically, the conservation status of Homalium densispicatum is officially designated as Not Evaluated. Current field registries estimate a global population composed of an unquantified number of individuals, making habitat preservation critical to maintaining their wild populations.

It is typically endemic to forest, mountain, showing great physiological synergy with its surroundings. In terms of dietary preferences, it relies primarily on a diet of c3 autotrophic photosynthesis, deep root mineral absorption, and carbon sequestration. It exhibits specialized adaptations centered around a deciduous summer foliage, vernal flowering, and seasonal seed dispersal activity pattern, optimizing its energy conservation and interactions within its native ecosystem. The species has a typical natural lifespan of approximately 150 years, allowing it to adapt and mature through structured generational cycles.

Ongoing biological monitoring and ecological advocacy emphasize the importance of protecting this species. The stability of its food chain and the prevention of fragmentation in its primary range are vital for the continued survival of Homalium densispicatum.
