The Cactaceae are represented in Peru by 43 genera and nearly 250 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mostly erect-columnar or sprawling cactus. Here we recognize 1999 endemic taxa in 32 genera. Six genera-Calymnanthium, Lasiocereus, Matucana, Mila, Oroya and Pygmaeocereus- are endemic to Peru. This family requires methodic efforts to increase the number of vouchers in national herbaria, as well as evaluations of the populations, habitats, taxonomy and systematics of these taxa. Most endemic taxa are found in the Desert Shrubland and Mesoandean regions, from sea level to 4000 m elevation. We applied IUCN categories and criteria to 58 taxa. Fifteen endemic taxa have been recorded in the Peruvian parks system.

A study of the vascular flora composition in the river Ilo-Moquegua basin and Lomas of Ilo is presented herein, at elevations that vary between sea level and 4600 meters, based on intensive collections, examination of herbarium specimens and bibliographic research. According to the present study, the vascular flora in the river Ilo-Moquegua basin and Lomas of Ilo was found to consist of 63 families, 233 genera and 394 species. Eighty three percent of the species are Magnoliopsida and 15% belong to the Liliopsida. Families with the largest number of genera and species are Asteraceae (41 genera and 60 species), Poaceae (28 and 44), Solanaceae (11 and 32), Fabaceae (17 and 26), Malvaceae (11 and 21), Brassicaceae (10 and 15), Boraginaceae (9 and 15) and Cactaceae (10 and 14). The dominant biological forms are herbs (69%), followed by shrubs (28%), climbing plants (4%), trees (2%) and parasi...

250 especies (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004), mayormente cactus arbustivo-columnares. En este trabajo reconocemos 199 endemismos en 32 géneros. Seis géneros, Calymnanthium, Lasiocereus, Matucana, Mila, Oroya y Pygmaeocereus son endémicos al Perú. Esta familia requiere de esfuerzos metódicos para incrementar su representación en los herbarios nacionales, asociados con una evaluación de las poblaciones y de sus hábitats, así como una evaluación de la taxonomía y sistemática de estos taxones. La mayoría de los taxones endémicos ocupan las regiones Matorral Desértico y Mesoandina, desde el nivel del mar hasta los 4000 m de altitud. Se aplicaron las categorías y criterios de la UICN a 58 taxones. Quince taxones endémicos están representados dentro del Sistema Nacional de Áreas Naturales Protegidas por el Estado.

We analyze Aurora Cáceres´ (1872-1958) personal scrapbook from a perspective grounded on the tenets of digital humanities and information science. By converting it into datasets, we aim to make machine readable such a complex and heterogeneous object, and also, comprehensively approachable, without ignoring the semantic complexity of the objects´ diverse materialities. We aim to overcome the traditional consideration of such complex devices as sources for extracting isolated information or limited to intimate and apolitical spheres. With her personal scrapbook, Cáceres, like other women intellectuals from her time, showcases her political agency, as well as the strategies deployed in order to build a history and memoir in which she has got a leading role. Moreover, having been released as open, the datasets can be profited from by other researchers worldwide. Therefore, this work aim...

Fátima Cáceres de Baldarrago was a Peruvian botanist recognized for her knowledge of the Cactaceae family and the flora of southern Peru. She had an active interest in the different aspects of "Scientia amabilis". Thus, her concern to learn from scientific collections, and the management and review of various taxa led her to do internships at the Instituto Nacional de Innovación Agraria, La Joya, Arequipa, and at the Herbarium Truxillense of the Universidad Nacional de Trujillo, La Libertad, as well as in the Museo de Historia Natural de la Universidad Nacional Mayor de San Marcos, which she created a permanent collaborative connection.

In its most recent concept, the genus Cheilanthes encompasses three clades distributed across South America, Africa, and Australasia. Previous studies in Peru recorded 23 species; however, advancements in molecular systematic have led to the segregation of eight of them into at least three genera. In this study, 15 species are recognized in the Peruvian flora based on the examination of 459 herbarium and field specimens, and the evaluation of morphological characters using 131 specimens. The affinities among the lineages proposed in this study are consistent with recent phylogenetic hypotheses, wherein Cheilanthes species in Peru are members of two clades, the South American and the Australasian-South American, with taxonomically important characters being the shape of rhizomatous scales and types of frond indumentum (scales, microscales, scuamules, and hairs). We found that the genus Ch...

El propósito del evento fue exponer, discutir y analizar temas como la definición de tipos de materiales que deben ser dispuestos en acceso abierto; la gestión de los datos crudos de investigación; la divulgación de datos públicos; la disposición, preservación y difusión de las obras en repositorios digitales de acceso abierto; los derechos de autor y la reproducibilidad de la Investigación.

This work focuses about the recent decisions made by the Ministry of Agriculture of Peru on the collection, propagation, and sowing of Cinchona species are reasons to point out the deficiencies of these decisions in light of advances in the knowledge of Cinchona taxonomy and systematics. We emphasize the role of the science analysing and informing about decisions in the sustainable use of natural resources.

This paper presents for the first time an overview of the state of current Peruvian journals. After retrieving and filtering records from LATINDEX, 138 journals were identified and characterized by the following variables: geographical origin, publisher, frequency, format (print, electronic, or both), and subject. The results show that Peruvian journals are mostly published in Lima (66.7%) by a university (73.9%), come out every six months (56.5%) both in print and electronically (67.4%), and publish articles mainly about natural sciences (35.5%). The article points out some problematic issues as well as certain measures for improving the Peruvian journal publishing market.

A total of 146 species of vascular plants, grouped in 124 genera and 52 families were recorded, among August 1997 and December 1998. The Magnolliopsidae (Dicotyledoneae) was the, dominant group with 115 species, 26 genera, and 8 families. There are not records for Gymnosperm. Three species represented the Pteridophyta. The more representative families were, the Asteraceae with 19 species, Poaceae with 16 species and Solanaceae with 13 species.

Puya raimondii is an endemic species from the high Andes of Peru and Bolivia. In Peru it is distributed from 8.068501°S, 16.170280°W to 16.180580°S, 70.658873°W, between 3600 and 4800 m, living in extreme climatic conditions typical of the Puna, where it plays an important ecological role. Despite the wide distribution of P. raimondii populations in Peru, they appear to be fairly uniform morphologically. The following questions arise: Will the current molecular tools be able to show differences between the numerous populations? Are the conservation areas established for P. raimondii sufficient since they harbor the existing variability? To answer these questions, this work aimed to evaluate the genetic diversity and genetic structure in a northern population, Pachapaqui (Ancash department), a central population, Yanacancha (Junin), and a southern population, Lampa - Choconchaca secto...
