Abstract
A systematic revision of the six nominal species of the Neotropical genus Manekia (Piperaceae) was completed after evaluation of morphological and molecular data. Phylogenetic analyses using four molecular markers (rpl32-trnLUAG spacer, psbj-petA intergenic intron regions 1 and 2, and internal transcribed spacer (ITS)) provided little resolution among species, perhaps indicating recent evolutionary divergence. Canonical discriminant analyses using morphological data recovered three separate groups, here recognized as distinct species: Manekia incurva, Manekia obtusa, and Manekia urbanii. Significant discriminating characteristics included petiole vagination, number of primary veins, leaf apex shape, leaf base shape, presence of pellucid dots, and bract ciliation.
