Kew Bulletin Aims and scope Submit manuscript


A new species of Impatiens, I. kunyitensis from Kerinci Seblat National Park,West Sumatra, Indonesia is described and illustrated. It has a unique combination of characters, including red and green stems and white flowers in which the lower sepal is bucciniform and abruptly constricted into a curved, short, violet spur. This combination of characters makes determining the relationships of I. kunyitensis difficult.
