“…In America the genus occurs from Bermuda and the southeastern United States (Boufford 1982) to southern Chile, central and littoral Argentina and southern Uruguay (IBODA 2015). Several morphological synapomorphies support this genus, such as a single carpel, unitegmic ovule, 16-nucleate embryo sac, two monothecal bisporangiated stamens, and small non-aperturate pollen (Tucker et al 1993, Jaramillo et al 2004, Wanke et al 2006.…”

The genus Peperomia is represented by eight species in Uruguay: P. catharinae, P. comarapana, P. hispidula, P. increscens, P. pereskiifolia, P. psilostachya, P. tetraphylla and P. trineuroides. Peperomia psilostachya is reported for the first time for the flora of Uruguay, from material collected in moist hillside and riverside forests from the northeast and east of the country. Three new synonyms are proposed: P. arechavaletae var. arechavaletae as synonym of P. trineuroides, P. arechavaletae var. minor of P. tetraphylla and P. trapezoidalis of P. psilostachya. Lectotypes for P. arechavaletae, P. arechavaletae var. minor and P. tacuariana, and a neotype for P. herteri are designated. The taxonomic treatment includes synonymies used in Uruguay, morphological descriptions, distribution and habitat data, phenology, conservation assesment, observations, and material examined for each species treated. A species identification key, plant illustrations and distribution maps in Uruguay are provided. ResumenEl género Peperomia está representado en Uruguay por ocho especies: P. catharinae, P. comarapana, P. hispidula, P. increscens, P. pereskiifolia, P. psilostachya, P. tetraphylla y P. trineuroides. Peperomia psilostachya es registrada por primera vez para la flora de Uruguay a partir de material colectado en bosques de quebrada y ribereños del noreste y este del país. Se proponen tres nuevas sinonimias: P. arechavaletae var. arechavaletae como sinónimo de P. trineuroides, P. arechavaletae var. minor de P. tetraphylla, y P. trapezoidalis de P. psilostachya. Se designan lectotipos para P. arechavaletae, P. arechavaletae var. minor y P. tacuariana, y un neotipo para P. herteri. El tratamiento taxonómico incluye para cada especie sinonimias usadas en Uruguay, descripciones morfológicas, datos de distribución y hábitat, fenología, evaluación del estatus de conservación, observaciones y material examinado. Asimismo, se presenta una clave para la identificación de las especies, ilustraciones y mapas de distribución en Uruguay.

“…Stamens in Piperaceae are stereotypically initiated with a pair in the lateral plane, followed by a primordium in the anterior position, and another single stamen in the posterior position (Tucker 1982). In looser inflorescences, such as in P. amalago, another pair of primordia is originated in the lateral plane of the flower (Tucker 1982); in tighter inflorescences like in P. umbellatum, only the first pair of stamens originates (Tucker et al 1993). However, this explanation does not seem to be universal.…”

“…Phylogenetic Justification. A morphological parsimony analysis using 24 morphological characters modified from matrices of Tucker et al (1993), Tucker and Douglas (1996), and Meng et al (2003) placed Saururus tuckerae in a single most parsimonious position within the family Saururaceae, as the sister group of a clade formed by the two extant species of Saururus (Smith and Stockey, 2007). The relationship of the fossil with extant Saururus, one of four genera in Saururaceae, was supported by the following synapomorphies: basally connate carpels, 1-2 ovules per carpel, and marginal placentation (Smith and Stockey, 2007).…”
