Two new species of Turraea L. are described from northern Madagascar, T. andriamiarisoana Callm., Phillipson & Lowry, sp. nov. and T. buerkii Callm., Phillipson & Lowry, sp. nov., both endemic to a region bounded by four relatively well-studied protected areas (Tsaratanana, Manongarivo, Marojejy and Anjanaharibe-Sud). The region harbors extensive low to high elevation humid forest that was botanically virtually unknown until recently. The new species differ from each other and from other members of the genus in Madagascar by leaf features, flower colour, length of the staminal appendices, and the shape and the pubescence of the ovary. Line drawings are provided for both of the new taxa, along with discussions of their morphological affinities and preliminary risk of extinction assessments.
