A Systematic Revision of the Genus Manekia (Piperaceae).

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 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 allowed for recognition of three distinct taxa: Manekia incurva, Manekia obtusa, and Manekia urbanii. Significant discriminating characteristics included petiole vagination, number of main veins, leaf apex shape, leaf base shape, gland presence and bract ciliation.
