    Note
    Impatiens tribuana is closely related to I. laumonieri T. Shimizu but can be distinguished by the dorsal petal which is reflexed/folded in the upper half, the yellow lower sepal with a red spot inside and the presence of two lateral sepals only; I. laumonieri has an orbicular dorsal petal, and four lateral sepals. The species epithet tribuana refers to the three elements: land, sea and air in which a special forces soldier must operate, in honour of TNI-KOPASSUS.
