Impatiens angustiflora Hook.f. (Balsaminaceae) re-collected from the type locality, Khasi Hills, Meghalaya, India after almost 67 years. The actual distributional range of the species has been discussed on actual data as there were erroneous reports of its occurrence. To facilitate its proper identity and easy identification, detailed description from live materials with coloured illustrations, comparison of characters with closely allied species are presented. The present status of the species in wild and measures of conservation are provided. A lectotype is designated here as no holotype was indicated in the protologue.

Abstract


Impatiens angustiflora Hook.f. (Balsaminaceae) re-collected from the type locality, Khasi Hills, Meghalaya, India after almost 67 years. The actual distributional range of the species has been discussed on actual data as there were erroneous reports of its occurrence. To facilitate its proper identity and easy identification, detailed description from live materials with coloured illustrations, comparison of characters with closely allied species are presented. The present status of the species in wild and measures of conservation are provided. A lectotype is designated here as no holotype was indicated in the protologue.
