I am very glad to see that Indian botanists are becoming aware of Impatiens edgeworthii as a problem. Last year in Central Germany about 1 million of this species did grow in Central Germany, most of them in the Leinawald (Leina forest) near Altenburg. >From the beginning I was aware the descriptions of this species in the Flora of Pakistan and elsewhere did not agree with what we are seeing in Germany.
