Current Perspectives on the Classification and Phylogenetics of the Genus Piper L.

A Late Cretaceous Piper (Piperaceae) from Colombia and diversification patterns for the genus

“…31 Ma: Naumann et al, 2013). An Early Cretaceous age, like the one obtained here, is, however, poorly supported by the fossil record, considering that the earliest evidence for an angiosperm dates back to only 136 Ma (Friis et al, 2006) and that Piper is relatively derived among Piperales (Jaramillo and Callejas, 2004). It is likely that the Early Cretaceous age estimated for the divergence of Piper is an overestimation and an inherent artifact in most calibration analyses dealing with early‐diverging lineages, since these are particularly prone to significant changes in extinction/diversification rates (Bromham and Penny, 2003; Friis et al, 2011), life history traits, and other factors that can affect substitution rates and push back the age of a lineage (Kay et al, 2006).…”

“…1). Additionally, the profound distinction in floral biology between paleotropical and neotropical species, which are dioecious and monoecious respectively, supports a deep divergence between these groups (Jaramillo and Manos, 2001; Jaramillo and Callejas, 2004).…”

Survey of medical ethnobotanicals for dental and oral medicine conditions and pathologies

“…We will conduct further medical anthropological, taxonomic, and ethnopharmacological studies to elucidate other plant families used for anesthesia, ant-inflammatory and anti-anxiety purposes. We anticipate phylogenetic PCR analysis, possibly following the Piper taxonomical work established by Callejas (1986) and the phylogenetic model of Jaramillo and Manos (2001) and Jaramillo and Callejas (2004), to clearly elucidate the genetic relationships between the various species of plants which are used by the indigenous and the rural public as public access, plant-based drugs for oral pain relief.…”

Taxonomic notes on the New Zealand flora: new names in Piper (Piperaceae)

“…and speciesrich Piper has been explored using cladistic and molecular methods (see Jaramillo & Manos 2001;Jaramillo & Callejas 2004;Wanke et al 2007). As a result Macropiper has been merged within Piper (Jaramillo et al 2008).…”
