The Asteraceae are the second most diverse family in the Peruvian flora, with approximately 250 genera and 1590 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004). Most Peruvian Asteraceae are herbs, shrubs and subshrubs. Here we recognize 724 endemic taxa, 695 at the species level and 29 varieties. The most species-rich genera are Senecio, Gynoxys and Verbesina. This family includes 11 genera endemic to Peru: Ascidiogyne, Aynia, Bishopanthus, Chucoa, Ellenbergia, Hughesia, Notobaccharis, Pseudonoseris, Schizotrichia, Syncretocarpus, and Uleophytum. Endemic taxa are mainly found in the Mesoandean, Pluvial Montane Forest and Very Humid Montane Forest regions, from sea level to above 4000 m. We assigned the IUCN categories and criteria to 567 taxa. Eightysix species (approximately 12% of all endemic Asteraceae) have been registered in a protected area.

For the district Laraos 155 species of asteraceae grouped into 66 genus, 12 tribes and 3 subfamilies are recorded. Senecio, Baccharis and Werneria are genus more wealth. Senecio larahuinensis and Conyza coronopifolia are new records for the flora of Peru as the first new species; further 35 species are new reports for Lima. Dichotomous keys for the identification of tribes, genus and species present.

We present 15 taxa of Malesherbia occurring in Peru, adding a new record, Malesherbia auristipulata. Updated data for departamental distribution, altitudinal range, and a species key are provided.

Senecio sagasteguii and Senecio qosqoensis (Asteraceae, Senecioneae), two new species from Cusco region, in southeastern Peru, are described and illustrated. Both new taxa are assigned to Senecio section Senecio series Chilenses subseries Caespitosi by its subshrubby habit and solitary or few discoid capitula. Some remarks on their possible morphological affinities, geographical distribution, and ecological preferences are supplied.

This paper analyses the distribution of Peruvian species of the genus Senecio, based on 4342 herbarium sheets with available localities and geographical coordinates. The Rivas-Martínez method of bioclimatic belts and the Köppen-Geiger model were used to determine how they are related to climate, and to observe their response in the face of climatic changes over 50 and 100 years. To observe the departmental distribution of the species and the relationship between departments in terms of presence-absence (UPGMA, Sørensen's coefficient) was used. A Principal Component Analysis (PCA) revealed the correlation of each species with mean altitude, mean climatic variables and mean Thermicity Index of the localities of a species, establishing 10 groups ordered by bioclimatic belts. Different distribution patterns were mapped, corresponding to bioclimatic belts and biogeographical provinces of P...

Las Asteraceae ocupan el segundo lugar entre las familias más diversas de la flora peruana. Esta familia es reconocida en el Perú por presentar alrededor de 250 géneros y 1590 especies (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mayormente hierbas, arbustos y subarbustos. En este trabajo se reconoce 724 endemismos, de los cuales 695 son especies y 29 variedades. Los géneros con mayor número de especies son Senecio, Gynoxys y Verbesina. Esta familia incluye 11 géneros endémicos del Perú: Ascidiogyne, Aynia, Bishopanthus, Chucoa, Ellenbergia, Hughesia, Notobaccharis, Pseudonoseris, Schizotrichia, Syncretocarpus y Uleophytum. Los endemismos reconocidos ocupan la mayoría de las regiones ecológicas, principalmente la Mesoandina, Bosques Pluviales Montanos y Bosques Muy Húmedos Montanos, desde el nivel del mar hasta por encima de los 4000 m de altitud. Se aplicaron las c...

El distrito de Laraos registra 155 especies de Asteráceas agrupadas en 66 géneros, 12 tribus y 3 subfamilias. Senecio, Werneria y Baccharis son los géneros con mayor riqueza. Senecio larahuinensis y Conyza coronopifolia son nuevos registros para la flora del Perú, siendo la primera como especie nueva; además 35 especies se reportan como nuevas para Lima. Se presentan claves dicotómicas para la determinación de las tribus, géneros y especies.

Se presentan 15 taxones de Malesherbia que ocurren en el Perú, incluyendo un nuevo registro, Malesherbia auristipulata. Se proporcionan datos actualizados de distribución departamental, rango altitudinal, además de una clave dicotómica para la determinación de las especies.

Senecio sagasteguii y Senecio qosqoensis (Asteraceae, Senecioneae), dos nuevas especies procedentes de la región Cusco, en el sureste del Perú, son descritas e ilustradas. Los nuevos taxones son asignados a Senecio sección Senecio serie Chilenses subserie Caespitosi en virtud de su hábito subarbustivo y sus capítulos discoides solitarios o escasos. Se incluyen algunos comentarios sobre sus posibles afinidades morfológicas, su distribución geográfica y sus preferencias ecológicas.

La orografía del Departamento de Lima se caracteriza por el acusado desnivel entre la costay las cumbres, albergando una gran riqueza florística de 1701 especies, de la que el 19,6% sonendemismos nacionales y un 3,2% endemismos departamentales; el 6,8% son especies introducidasderivadas de la acción antrópica sobre el territorio, la mayor parte de ellas procedentes de Eurasiay África. Debido a la aridez del clima, causada por sombra de lluvias que ejercen los Andes y a lasprecipitaciones debidas a la inversión térmica prolongada originada por la corriente oceánica fría deHumboldt, la mayor parte de las formas de vida son hierbas (78,2%). El paisaje de Lima se sintetizaen 5 pisos bioclimáticos (termotropical, mesotropical, supratropical, orotropical y criorotropical)entre los cuales se encuentra repartida la flora. El piso termotropical es el más diverso en especies(291), endem...

Se presenta el primer documento sobre Asteráceas cultivadas en el Perú, con 53 especies en37 géneros. 44 especies son introducidas de Asia, Mesoamérica, Europa, África y Australia,y solamente nueve son nativas de Sudamérica. Siete especies son nuevos registros para la floraperuana. Mayormente son de hábito herbáceo y categorizadas como ornamentales.

Eighth species of Asteraceae are recorded as new for the Peruvian flora.flora of Peru are reported. Elapahandra lehmannii and Mutisia magnifica were previously known from Ecuador, whereas Achyrocline latifola, Baccharis tridentata and Ericentrodea davidsmithi from Bolivia. Chaptalia piloselloides and Hieracium erianthum are widely distributed in South America and Bellis perennis is a native species of Europe.

In this paper, the inventory of vascular plants of high mountains (altitudes of 4000-4810 m) from northeast Oyon district, Lima, Peru is presented. Specimens were collected during March to May 2014 and 2015 and September to November 2015. 47 families, 112 genera and 181 species are reported, of which 94 were the first record for Lima region. For each species are given collector names, collect number and elevation. New local botanical inventories are needed for better evaluating the diversity, species distribution patterns and endemism in the high Andean vegetation.

En este trabajo se presenta el inventario de plantas vasculares de montaña alta (altitudes de 4000 a 4810 m) del noreste del distrito de Oyón, región Lima, Perú. Las colectas se realizaron durante los periodos marzo a mayo de 2014 y de 2015, y setiembre a noviembre de 2014. Se encontraron 47 familias, 112 géneros y 181 especies, de las cuales 94 no estaban registradas para la región Lima. Se presenta la lista de todas las especies encontradas con referencia a los colectores, número de colecta y altitud de colecta. Se argumenta la necesidad de multiplicar los inventarios botánicos locales que permitirían conocer mejor la diversidad de la flora, la distribución de las especies, y los endemismos en la vegetación altoandina.

Between 2000 and 2016 we carried out 15 rapid biological inventories in remote areas of the Andean foothills and Amazon basin in Peru. During these inventories, 27 botanists collected 9397 fertile vascular plant specimens. By the end of 2017, more than half of these specimens had been identified to species. Of the 2303 species identified to date, 64 species and 2 genera (Dicorynia and Monopteryx) are new records for the flora of Peru. If this rate of discovery proves typical, the number of new records for Peru in the rapid inventory material could increase, which indicates that there is still much to discover in the Peruvian flora.
