New taxa of Impatiens (Balsaminaceae) from Madagascar. I

In a first paper as precursor to a revision of Balsaminaceae in Madagascar and the Comoro Islands, fourteen species of Impatiens (Balsaminaceae) are described as new (I. gautieri, I. bemarahensis, I. emiliae, I. begonioides, I. silviana, I. andohahelae, I. malcomberi, I. ranomafanae, I. translucida, I. albopurpurea, I. navicula, I. mandrakae, I. mananteninae, and I. pilosissima). Two nomina nova (I. mandrarensis for I. acaulis, and I. bathiei for I. manongarivensis var. miniata) are proposed. A short history of the exploration of Impatiens in Madagascar is provided.
