Scientific Summary

GBIF Taxonomic Backbone & Wikipedia Registry Profile

Description FRUIT. Elliptical with acute apex, laterally compressed, brown when mature. Epicarp puberulent with two types of hairs, simple hairs with granular ornamentation and small papillae-like hair expansions that line the fruit; faintly rugose when dry, revealing the underlying endocarp ridges. Mesocarp 200 – 400 µm thick when dry. Length 25 – 35 mm, width 16.5 – 26.0 mm, thickness 10 – 17 mm. ENDOCARP. Elliptical in lateral view, lenticular in transverse section, length ca 25.6 mm, width ca 16.3 mm, thickness ca 12 mm. Keel running along the dorsal length of the endocarp, flanked by two channels, with the vascular bundle embedded within keel / endocarp wall; a single channel runs along the ventral length of the endocarp. Apex acute, asymmetrical, forming a rectangular protuberance; base rounded-acute and slightly asymmetrical. Outer surface of the endocarp rugged with ca 90 mounds, more or less square-polygonal, with freely ending channels inside, more or less branched. Mounds organized in 9 – 12 longitudinal lines separated by 5 – 6 main longitudinal channels. The main channel on each face reaching the pore positioned subapically on the apical protuberance. Vasculature of the endocarp resting in the channels between mounds and along the channel branches inside the mounds. Endocarp wall 289 – 372 µm thick excluding mounds (460 – 544 µm including mounds). Endocarp wall with two cell layers: outermost layer with 8 – 9 rows of anticlinally oriented to isodiametric cells, cells 22 – 31 µm in length; innermost layer with 5 – 6 rows of periclinally oriented cells, cells 14 – 21 µm in width. Locule surface smooth, lacunate.
Biology & Conservation

Ecologically, the conservation status of elima bidji 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 deciduous woodlands, tropical rainforest canopies, and fertile alluvial valleys, 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 elima bidji.
