| Summary: | <i>Impatiens reidii</i> Hook.f., a presumed extinct and Kumaon endemic species only known from its type collection in 1886, is rediscovered from near type locality after a gap of 138 years. The identity of the historically ambiguous name <i>Impatiens tingens</i> Edgew. is reinvestigated based on studies of literature, type specimens, and recollection of live material from the type locality that confirmed the name <i>I. tingens</i> is conspecific with <i>I. scullyi</i> Hook.f. and thus latter name is synonymised. <i>Impatiens inayatii</i> Hook.f., another little-known species described by Hooker as endemic to Kali valley, Kumaon currently treated as a synonym of <i>Impatiens bicornuta</i> Wall., is recollected from near the type locality after 124 years. Our recollection confirms its identity as a totally distinct species from section <i>Urticifoliae</i> S.Akiyama and H.Ohba, thus reinstating name <i>I. inayatii</i>. Augmented description for all three species is provided with information on their botanical history, species etymology, key identification characteristics, distribution, phenology, ecology, and first photographic documentation of <i>I. reidii</i> and <i>I. inayatii</i>. Also, lectotypes are designated for the names <i>I. reidii</i>, <i>I. tingens</i>, <i>I. laxiflora</i> var. <i>stracheyi</i> Hook.f. and <i>I. micranthemum</i> Edgew. |
