GBIF Taxonomic Backbone & Wikipedia Registry Profile

Description. Herb biennial, dwarf, densely covered with short glandular hairs. Leaves 9 - 25 in an open rosette; petiole 1.0 - 2.0 cm long; leaf blade pinnatisect, 4.0 - 8.0 cm long, 1.0 - 2.0 cm wide; pinnae 5 - 9 pairs, elliptic, margin usually pinnatifid, segments 3 - 5, apex mucronulate. Scapes 1 - 8 in each plant, 0.8 - 2.0 (- 2.5) cm tall, carrying one umbel, usually 3 flowers per umbel; bracts linear lanceolate, 2 - 3 mm long. Pedicel slender, 0.3 - 0.8 cm. Flowers long homostylous. Calyx narrowly campanulate, 1.0 - 3.0 mm long, split to the middle; lobes lanceolate, apex acuminate, not outward curvature. Corolla pale red, flowers' limb 8.0 - 12.0 mm across, lobes obovate, ca. 2.5 mm wide, apex conspicuously emarginate, corolla tube 5.8 - 7.0 mm, both stamens and stigma at the mouth of the corolla tube, pollen sac black. Capsule subglobose, 1.0 - 3.0 mm in diam., dehiscing by valves.
Biology & Conservation

Ecologically, the conservation status of Primula xinningensis 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 cave, 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 Primula xinningensis.
