    Note
    The specific epithet refers to the collecting locality, Mt Kunyit, where this species was first recognised. Impatiens kunyitensis is easily distinguished from all other Sumatran Impatiens species. 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 it difficult to determine the relationships of I. kunyitensis to other taxa. At first glance it even looks like a species of Paphiopedilum Pfitzer. Grey-Wilson (1989) noted that, within Malesia, Sumatra seems to correspond to a centre of species diversity and its evolutionary complexity is unparalleled amongst the islands of South East Asia. Therefore, it is not surprising that many new taxa of Impatiens have been, and are likely to be, found on Sumatra. The specimen collected from the field did not have good flowers. Therefore flowers were taken from cultivated material in Cibodas Botanical Garden, Java, to supplement the type.
