Impatiens x pacifica (Balsaminaceae), a new hybrid Jewelweed from the Pacific Northwest coast of North America

Impatiens x pacifica Zika (Balsaminaceae), a natural spontaneous hybrid, is described from western North America, in coastal Oregon and Washington. A key is provided, and the hybrid is compared with its parents, the common introduction Impatiens capensis Meerburgh and the uncommon native L ecalcarata Blankinship. Hybrid flowers are intermediate in markings and morphology between those of the parents. Impatiens x pacifica differs from L ecalcarata in its spotted corolla and from L capensis in its spurless flowers.
