Abstract
Impatiens longcanggouensis Q. Luo (Balsaminaceae), a new species from Yingjing County, Sichuan Province, China, is described and illustrated. Its morphology, including pollen and seed characters observed via scanning electron microscopy (SEM), is documented in detail. The new species is morphologically similar to I. recurvicornis, but is readily distinguished by the following combination of characters: leaf margin shallowly arcuate-serrate (vs. serrulate); abaxial leaf surface usually purplish-red (vs. pale green); inflorescence commonly two-flowered (vs. one-flowered); bracts lanceolate, 2–2.5 mm long (vs. ovate, 3–4 mm long); flowers 1.2–1.8 cm long (vs. 3–4 cm long); dorsal petal 6–8 mm in diameter, with two erect, stout rostella along the abaxial mid-vein (vs. dorsal petal ca. 13 mm in diameter with a beaked apex); lower sepal narrowly funnel-form with a spreading mouth (vs. navicular with an oblique mouth); and capsule clavate (vs. linear).
