Abstract

The new species Impatiens serusiauxii is described from Marojejy National Park in NE Madagascar. Impatiens serusiauxii differs from the morphologically similar I. manaharensis in the distinctly coriaceous linear-lanceolate leaves, the larger white flowers with dark red and yellow spots, the shape of the dorsal petal and the lateral united petals, and the shape of the lateral sepals and the lower sepal with spur oriented upwards. Impatiens serusiauxii is restricted to sclerophyllous montane cloud forest above 1100 m.
