New Piper species from the eastern slopes of the Andes in northern South America

Abstract

We describe four new species of Piper from the Amazonian slopes of the northern Andes. Piper hoyoscardozii is distinguished from similar climbing species, P. dryadum and P. flagellicuspe, by its longer peduncles. The Amazonian species Piper indiwasii is distinguished from P. scutilimbum from Panama and northern Colombia by the narrowly spatulate leaf base extension. Piper nokaidoyitau is characterised by the presence of larger leaves and longer spikes than similar species, P. anonifolium and P. hostmannianum. Finally, P. velae is characterised by cordulate leaf bases in all nodes, petioles 0.8–1.5 cm long and pubescent fruits, which easily distinguish it from the related species, P. holdridgeanum.

A new species of Piper (Piperaceae) with peltate leaves from Serranía de las Quinchas, Colombia

“…To the trained specialist, new Piper species are a common finding in the tropical forests, or even in the undetermined piles in the most important herbaria around the world. Additionally, molecular phylogenetics have confirmed the clade (subgeneric) affiliation of new species ( Bornstein et al 2014 ; Tepe et al 2014 ; Trujillo et al 2022 ). During our exploration to Serranía de las Quinchas we have identified a few undescribed species, one of the stands-out because it has peltate leaves, a characteristic rarely observed in the genus.…”

“…Molecular phylogenetics demonstrated that Trianaeopiper is not monophyletic, revealing that the diagnostic character axillary inflorescence – which are shortened sympodial branches, is convergent ( Jaramillo and Callejas-Posada 2004 ). Similarly, molecular phylogenetics have further supported that Piper species with peltate leaves are part of at least four Neotropical Piper clades ( Trujillo et al 2022 ). Piper classification, evolution and ecological studies have been greatly enriched with molecular phylogenetics.…”

“…Molecular phylogenetic studies have been instrumental in reviving the infrageneric classification of the genus, but also identifying convergence in morphological traits ( Jaramillo and Callejas-Posada 2004 ; Trujillo et al 2022 ). Molecular phylogenetics ( Jaramillo and Manos 2001 ; Jaramillo et al 2008 ) have validated the monophyly of groupings proposed in the mid-1800s ( Kunth 1839 ; Miquel 1843 ).…”

Deciphering anti-infectious compounds from Peruvian medicinal Cordoncillos extract library through multiplexed assays and chemical profiling

“…Among these, Piper is the most diverse and representative genus, encompassing ca. 2600 species ( Trujillo et al, 2022 ). Besides pungent compounds, many Piper species produce essential oils and are hence highly aromatic, explaining their use for cooking and medicinal purposes ( Ruiz-Vásquez et al, 2022 ).…”
