Abstrakt: Impatiens nimspurjae (Impatiens, Balsaminaceae), a new species from Nepal is described based on molecular data and morphological characters. Notes on the diagnostic characters used to distinguish it from allied taxa are provided. I. nimspurjae is closely related with taxon belonging to sect. Racemosae (I. harae, I. radiata, I. wallichii, I. urticifolia) in having many-flowered racemose inflorescences, lateral sepals 2 (very rarely 4 with inner 2 reduced), capsule linear, seed ovoid, but differs by its sessile leaves, upper lobe of lower united petal not truncated, spur flattened at base.
