Taxonomy and Typification of Indian Endemic Impatiens goughii (Balsaminaceae)

Morphological variation in Impatiens goughii (Balsaminaceae) from different areas of the southern Western Ghats, India, is studied and discussed, including an amended morphological circumscription of the taxon. An epitype and a lectotype are designated for I. goughii, and I. danii, I. omissa, I. parvifolia and I. raktakesara are synonymized with it. Additionally, lectotypes are designated for I. anamallayensis and I. microtheca.
