Abstract

Cuatrecasanthus is native to Ecuador and Peru and although several unusual characters define the genus, such as single flowered heads and corolla throat (limb) divided to the base with lobes that are thickened at the margins, the members of the genus were not recognized as especially closely related until relatively recently. All six species are described, including two new to science (Cuatrecasanthus kingii H. Rob. & V.A. Funk, sp. nov. and Cuatrecasanthus lanceolatus H. Rob. & V.A. Funk, sp. nov.), and one new combination is recognized (Cuatrecasanthus giannasii (Stutts) H. Rob. & V.A. Funk, comb. nov.). A key is provided along with images of the types, SEM photographs of the leaf surfaces, a distribution map, and illustrations of the two new species. All species are given a preliminary conservation status of Data Deficient in regard to the IUCN Red List of Threatened Species.
