Description
Gentiana pedicellata is a small annual gentian widely distributed across the Himalaya and into south-western China and Sri Lanka, with records also from Myanmar, Laos and Bangladesh and a documented base of some 466 occurrences (European and East Asian points largely cultivated or curated). It occupies open grassy slopes, terraced fields, forest clearings and moist disturbed ground over a broad altitudinal span. The images here span eastern Nepal's Jaljale Himal at 2900 m in April, Nundhaki at 1600 m in March, and Gumghadi in west Nepal at 2400 m in June, reflecting a flowering season tied to spring and early summer at middle elevations.
The plant is a slender, diminutive annual a few centimetres to about 15 cm tall, often branched from the base. The leaves are small, opposite, ovate to elliptic, sessile or shortly petiolate and somewhat fleshy, the lower forming a loose basal rosette. The flowers are solitary and terminal on conspicuously elongate, thread-like pedicels (the source of the epithet), the calyx tubular with five lobes, and the corolla narrowly funnel-shaped, pale blue to bluish-white with intervening plicate folds between the five spreading lobes. The fruit is a stalked, two-valved capsule exserted from the persistent calyx, releasing numerous minute seeds.
Gentiana pedicellata belongs to the Gentianaceae and to the annual gentians (section Chondrophyllae), a group well represented in the temperate Himalaya by many small, ephemeral species. Its long pedicels readily distinguish it from related dwarf annuals. The flowers are insect-pollinated, opening in bright conditions, and the light seeds are dispersed passively. Common, weedy and adaptable across a wide range, the species is of least conservation concern.
