That's true. Now it is treated as a synonym of
Impatiens bicornuta. The time this was put on the site, the main reference we looked at was the attached paper by Grey-Wilson on Impatiens bicornuta, where he differentiates it from Impatiens pradhanii. Also, the yellow flowers of I. pradhanii look so different, mainly in color, from the pink I. bicornuta. That is the reason for having a separate page for the two. Maybe I will keep the separate pages for the yellow and pink form, while retaining the accepted name Impatiens bicornuta.
