Background The Neotropics are considered one of the most biodiverse areas in the world, housing at least one third of all vascular plant species. One of the genera that has diversified in the Neotropics is Magnolia , with about 174 species of three sections ( Macrophylla , Magnolia and Talauma ) endemic to the Americas. In this work, we study the b...

Despite extensive research into the phylogenetic relationships of the genus Magnolia, Neotropical taxa have been neglected. This is partly because their numbers have recently doubled and now account for almost half of the global richness. Therefore, by sampling one-third of all Neotropical taxa their relationships were studied using morphological,...

The Saña River Valley in Northern Peru is unusual for the western slopes of the Peruvian Andes because of its nearly year-round regime of precipitation instead of marked seasonal dry winters. This results in unexpected plant diversity. We surveyed the species of Peperomia (Piperaceae), occurring in this valley from 300 to 3000 m elevation, based on...

A new genus and species of cactus from central Peru is described

Two new geophytic species of Peperomia subgenus Tildenia (Piperaceae) from Central Peru are described; (1) Peperomia pachyspadix is a new species from Huancavelica. It is phenotypically similar to P. andina from Cajamarca, but its leaves are not as thick and they lack the funnel shape and purple color of the abaxial side; it is also similar to P. w...

The Crassulaceae of the department of Huancavelica, Peru are updated. Two new species of Echeveria and one species of genus Sedum are described: Echeveria incaica from province Tayacaja near the border with Junn is morphologically similar to E. oreophila from Cajamarca; Echeveria ostolazae from the province Castrovirreyna at the southern border of...

Strophocactus krammii (Cactaceae) from the Peruvian Amazon region is described. It was first determined as Strophocactus wittii, a species form the Northern Amazon region, but thanks to the research of the German palinologist and ethnobotanist Erich Kramm from 1993 to 2019, enough data and material were collected in order to differentiate it as a n...

Sedum hutchisonii, a new species of Sedum endemic from Peru is described. First collected by Paul Hutchison in Huancabamba 56 years ago, then by Myron Kimnach in Cajamarca 18 years later, and more recently by the two authors, it has been erroneously taken for Sedum incarum, S. jujuyense, S. reniforme, S. andinum and S. grandyi. It is rare, but it h...

The small subgenus Panicularia, in Peperomia is mostly restricted to the dry seasonal valleys of Peru and Ecuador. Its representatives are very succulent during the dry period of the year, whereas in the rainy season they produce less succulent reproductive structures that die back after blooming. Four species from Peru are presented here, the latt...

The current status of genus Echeveria in Ecuador is reviewed. Although in 1994 Alina Freire-Ferro transferred all species in Ecuador to one taxon: E. quitensis, which she considered a single, variable species, we believe there are considerable differences, enough to consider some separate species and varieties. Plants found around the city of Quito...

The succulent endemic species of Crassulaceae in Argentina are reviewed and three new taxa are described. Echeveria argentinensis is a new species already collected 80 years ago in the Quebrada of Humahuaca at Jujuy between 2700 and 3600 m, determined primarily as E. peruviana. Hutchison recognized it as a new species 50 years ago and recorded this...

Three taxa of succulent Crassulaceae: Two Echeveria, and one Sedum were found in the Southern Departments of Perú. (1) Echeveria peruviana, a species described 180 years ago, was not found until recently in its type locality, a full description is provided and more localities in the departments of Tacna and Moquegua are given. (2) Echeveria vulcani...

A new subspecies of Matucana intertexta from the province of Cajabamba, in the extreme South of Cajamarca, Peru, is described. The type ofMatucana intertexta has previously been reviewed in this journal by the first author. In that paper its distribution is extended to four districts of the province of San Marcos and one of the provinces of Cajabam...

Se describe Echeveria cerrateana, una nueva especie de Ancash, Perú. El epíteto está dedicado a Emma Cerrate, la botánica peruana que la descubrió y quien hizo la mayoría de sus primeras colectas. Esta especie ha sido confundida en el pasado con E. chiclensis y E. excelsa, dos especies también con raíces tuberosas, pero en esta nueva, ellas emergen...

The Echeverias of the Chillón River Valley, one of the three rivers that run through Lima, the Capital city of Perú, are reviewed. Three new taxa are recognized and described: two new species and a new variety. (1) Echeveria deltoidea is a large species with narrowly triangular, light green to glaucous-purplish leaves, and large salmon-colored wide...

Three new species of Senecio (Compositae: Senecioneae) from Central Peru are described and illustrated. Morphological characters are used in order to distinguish them from the closest species. Senecio crassiandinus Montesinos & Pino has succulent leaves with cuticle composed of translucid white glands, bright yellow disc florets with blotches of pa...

Six taxa of Echeveria (Crassulaceae) were found around the Sacred Valley in the Department of Cusco, Perú. (1) Echeveria cuscoensis, is a new, widespread species from the upper basin of the Sacred Valley (Vilcanota River) and is described from the ruins of P'isaq due to its abundance there. It has faceted rhomboid leaves, concave or canaliculate ab...

Revisamos la especie Villadia virgata (Diels) Baehni & J. F. Macbride, descrita en Chiquián, Ancash, Perú. Fue colectada por Weberbauer en 1903, y descrita primariamente como Cotyledon virgata, para ser luego colocada en el género Villadia por Macbride. Aclaramos que las especies peruanas de Sedum tienen inflorescencias terminales ramificadas, mien...

The classification of species-rich genera is one of the most challenging tasks in systematics. In this paper we present an updated infrageneric classification of the genus Peperomia (Piperaceae), one of the most species-rich genera of plants. The classification is based on a molecular phylogeny of 190 accessions and the placement of 1340 of the 160...

The pantropical genus Peperomia consists of approximately 1,600 species with highest diversity in the Neotropics, especially in the Andes of Peru. Our continuous field work in this country shows that a considerable amount of new species still await discovery. Following our studies of the tuberous species of Peperomia subgenus Tildenia from the Ande...

Aim Peperomia subgenus Tildenia consists of c. 60 species growing in seasonal habitats of Neotropical mountain areas from Mexico to Argentina. The subgenus can be split geographically, with almost equal diversity in the Northern Hemisphere (centred in Mexico and Guatemala) and in the Southern Hemisphere (centred in Peru and Bolivia). Only a few spe...

and aims - The pantropical genus Peperomia consists of approximately 1,600 species with an extremely diverse vegetative morphology, especially in the Neotropics. One of the most startling yet overlooked growth forms is the geophytic one, as in subgenus Tildenia. This group occurs in seasonal Neotropical habitats with its highest diversity in Mexico...

The succulent medicinal Peperomias of Perú are reviewed. Peperomia congona is a valid name for this species, previously misidentified in Herbaria and texts as P. inaequalifolia. It is only found in cultivation and it is the most important medicinal Peperomia, used as digestive and anti-inflammatory. The true P. inaequalifolia R et P. has small and...

Eleven species of Crassulaceae were found in the Department of Cajamarca, northern Peru. (1) Echeveria eurychlamys was collected at its type locality for the first time since its description. (2) Geographical variants of Echeveria oreophila are described. (3) Echeveria cuencaensis, known previously only from Ecuador, is reported for the first time...

A new species and three new varieties of Peperomia from northern Perú are described. Three of them are plants collected and named by Paul Hutchison but never published. Peperomia columnaris looks like an erect-growing variety of P. nivalis, but its inflorescences and fruit structure suggest it is closer to P. ferreyrae and P. columella. Peperomia d...

En el 2003 visité el Perú y observé ahí el más común de los Agaves que se pudiesen encontrar, determinado como: Agave americana var. expansa (Jacobi) Gentry. Inmediatamente tomé nota de sus diferencias con el taxon que se dice ser, de origen mexicano (Jalisco) que habría sido introducido en época precolombina, pero al caer gravemente enfermo, las c...

Six little-known Crassulaceae from central Peru are discussed. (1) Echeveria excelsa, the largest species of this genus in Peru, is found for the first time at its type locality since Weberbauer's visit in 1906, and a new type is designated for it; (2) Sedum andinum is perhaps the smallest Sedum species in Peru; it has almost spherical leaves, and...

Echeveria andicola Pino, a new species endemic to central Peru, is described. Although fairly common in the departments of Junín, Pasco and Huánuco, the plants had formerly been identified as E. chiclensis or E. peruviana; however, careful analysis supports the recognition of these plants as an unpublished species. A comparison with other similar s...

Master Thesis reviewing the species of Peperomia of the Province Cajamarca, Cajamarca, Perú.20 taxa are described, including three new species, two new varieties and a form. Later, the new varieties described were raised to species and a new species from the book was described.

A new species and three new varieties of Peperomia are described from the province of San Marcos, Peru. Peperomia strawii Sp. nov., first found by Hutchison in 1964 in La Libertad, resembles P. trollii P. C. Hutchison & W. Rauh, but is generally smaller and has distinct inflorescences and leaf-sections. Peperomia cereoides var. reducta var. nov. di...

Described are two new species of Peperomia and a new variety of P. nivalis from the province of San Marcos, Peru. Peperomia cereoides has an appearance unique in the genus because of its minute leaves on thick stems, resembling those of a branched cereoid cactus. Peperomia liclicensis is prostrate, growing in mosses, and has cymbi- form apical leav...

Echeveria chiclensis (Ball) Berger and its forma backebergii (Poelln.) Kimn., taxa endemic to central Peru, are reviewed. The locations of all previous collections were revisited and ten new localities were found. After careful analysis of macro- and micro-morphological data, we conclude that there is evidence to support the recognition of two vari...
