Scientific Summary

GBIF Taxonomic Backbone & Wikipedia Registry Profile

Description Epiphytic shrub, glabrous. Stem terete, slightly canaliculate when dry. Internodes broadening slightly at base and apex, (0.5 –) 2 – 4 (– 6) cm × 2 – 3 mm. Leaf-blades obovate to elliptic, 9 – 17 × 2 – 4.5 cm, apex acute to acuminate, acumen 5 mm long if acuminate, base truncate, midrib raised adaxially and abaxially, secondary nerves 8 – 11 on each side of the midrib, petioles 0.5 – 3 cm long. Stipule broadly triangular, 4 – 5 × 5 mm, sometimes bilobed when broken, margin with terminal colleters, inside with standard colleters 0.5 – 1 mm long. Inflorescence a compound cyme, 4.5 – 7 cm long, peduncle 0.8 – 4 cm long, internodes of rachis 0.5 – 1.5 cm long, each node of inflorescence including capitulum with 4 bracts, triangular, margin with teeth, 2 broader bracts 0.5 – 1.5 × 0.5 – 1 mm, 2 narrower bracts 1.5 × 0.5 mm. Open flowers not seen. Fruits narrowly ellipsoid, 5 – 6 × 4 mm, with pedicels 5 – 6 mm long. Pyrene dorsal surface rough, with a central longitudinal groove 1.5 – 2 mm wide, pyrene ventral surface with a central groove 1.5 – 2 mm wide and a ridge at centre of the groove 0.5 mm wide and as high as the plane of the endocarpal outgrowth, the 2 grooves between endocarpal outgrowth and pyrene margin 0.1 mm wide or absent. Seed not seen.
Biology & Conservation

Ecologically, the conservation status of Chassalia javanica 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 Chassalia javanica.
