Abstract

Impatiens lutzii, a new species of Impatiens subg. Trimorphopetalum, is described from Montagne d’Ambre, Madagascar. It is morphologically similar to Impatiens luisae-echterae, I. callmanderi and I. silviana from Masoala, and to I. decaryana from central Madagascar, but differs from these species in the shape and ornamentation of the lower sepal, as well as the shape of the dorsal petal and the lateral united petals. A comparative table to distinguish I. lutzii from similar species of Impatiens is provided.
