<I>Borreria krapocarmeniana</I>, a New Cryptic Species Recovered Through Taxonomic Analyses of <I>Borreria scabiosoides</I> and <I>Borreria linoides</I> (Spermacoceae, Rubiaceae)

Abstract The new species Borreria krapocarmeniana (Rubiaceae) is described and illustrated. The taxonomic identity of Borreria linoides and Borreria scabiosoides are discussed. Borreria organensis and Borreria rubricaulis are proposed as new synonyms of B. scabiosoides. Seed micromorphology and pollen grains of the three species are analyzed and a map with the distribution of these species is presented. Additionally, a table featuring diagnostic characters to distinguish between species is provided.
