I digged some in the subject and I think that all these whitish or rosa Impatiens with rounded posterior part of lower sepal, abruptly narrowing into spur and rusty markings on lateral petals are I. devendrae. However I found old drawing (Tab. 6550 in http://www.botanicus.org/item/31753002721816) depicting I. amphorata. As you can see this plant is almost identical with I. devendrae by Pusalkar and I. amphorata in Mr. Impatiens gallery http://www.mrimpatiens.com/scripts/gallery.php?gallery=species&specimenfile=Impatiens%20amphorata.jpg In accompanying text from 1881 Hooker wrote that this form (I. amphorata depicted in Tab. 6550) is different from typical form of I. bicolor. Unfortunately, later he changed his opinion and lumped I. amphorata, I. pallens and I. umbrosa under I. bicolor (picture of this species from Mr. Impatiens gallery http://www.mrimpatiens.com/scripts/gallery.php?gallery=species&specimenfile=Impatiens%20bicolor.JPG) another picture of I. bicolor from old literature http://www.botanicus.org/item/31753002075122, see volume 2, Tab. 28, left plant Please notice differences in proportion of upper and lateral petals between I. amphorata from Tab. 6550 and proper I. bicolor. For me these two are without any doubts separate species. In conclusion, looks like Hooker's opinion from 1905, later repeated by local and general Indian floras gave way for description of "new" species I. devendrae. Please remember however that all what I see are pictures and descriptions which sometimes could be misleading - in accompanying text to Tab. 6550 Hooker describes colour of flowers as pale purple (!)
