The lauraceae collected in brazil by ludwig riedel - I

The species of Lauraceae collected by Ludwig Riedel, excluding Ocotea, are commented and contex-tualized according to the different itineraries he travelled in Brazil, from 1821 to 1836, indicating the localities and dates of collections, whenever possible. To complete this work, two diaries of Riedel have been consulted and the information from them cross-checked with the annotations found on specimen labels. An annotated list of 48 entries provides information on the status of species names and their types, currently accepted names, and collections found in different herbaria. Lectotypes for five names, Aydendron verrucosum var. attenuata, Aydendron parviflorum, Mespilodaphne parviflora, Nectandra spicata, and Oreodaphne fasciculata, are designated. The species of Ocotea collected by Riedel will be treated in part II of this series. © President and Fellows of Harvard College, 2012.

The collections of Lauraceae in the Herbarium of Henri Van Heurck (AWH)

Background and aims - The collections of Lauraceae in the Van Heurck Herbarium (AWH), which is currently on permanent loan to BR, have remained unknown by most of the specialists and by the general public up until the present. The taxonomic status of its one hundred and forty nine specimens of Lauraceae is here presented.Methods - Standard herbarium taxonomy practices were used in conjunction with the literature available. Specimens from fifty eight different herbaria were studied personally, or by checking their holdings available in the internet, or from digital images received from the curators.Key results - The specimens of Lauraceae from AWH are distributed in twenty four genera and seventy eight species with taxonomic status resolved, excepting for three specimens pertaining to species name of status uncertain (one), or to unresolved determination (two). From them, fifty three specimens are nomenclatural types of any sort, which corroborate the relevance of exsiccates acquired by Van Heurck, even for this relatively small set of specimens for the family. Fifteen lectotypifications and one neotypification of species names are proposed here.

Plantas medicinais: indicação popular de uso no tratamento de hipertensão arterial sistêmica (HAS)

The aim of this study is to investigate the spontaneous use of medicinal plants by volunteer patients in the treatment of hypertension and to determine the most used plants in this situation. Data were collected through a questionnaire and a semi-structured guided interview applied to patients from a health center in the Midwest region of the state of Sao Paulo, Brazil. Quantitative analysis identified a high number of hypertensive patients spontaneously using herbal treatment. The referred plants were identified by the Herbarium Botu and researched in the literature as to their therapeutic actions. The biggest mistake was observed in the misuse of the Bilberry for the treatment of hypertension, which reveals that health professionals and the community in general should be more careful. As a result we have published an informative booklet, with emphasis on hypertension concepts and on the use of medicinal plants as an alternative therapy method for this disease in order to provide scientific knowledge and scientific research evidence to this practice.

Establishment of Regional Herbarium Leads to More Than 200 New Flora Atlas Records for New York State

Loss of small herbaria is an unfortunate global trend, and initiation of new collections at small academic institutions is an increasingly rare occurrence. In 2006, a new herbarium was established at the State University of New York College at Plattsburgh. The PLAT herbarium has since grown to more than 7,000 specimens, many of them representative of the flora of northeastern New York (especially Clinton County). Previous to 2006, this region was without a recognized herbarium, the nearest in-state collections being more than 150 miles away. Although botanists have previously worked in the region, relatively few plant species were recorded for Clinton County by the New York Flora Atlas – a resource providing species distribution records based on specimens accessioned in herbarium collections. Given the dearth of available distribution data for Clinton County (including the eastern Adirondack Mountains and the western Lake Champlain valley), this project sought to provide records of previously unreported species by comparing NY Flora Atlas maps with current holdings. 203 species will now be added to the NY Flora Atlas for Clinton County, roughly half of those considered exotic. This exercise has amplified the importance of supporting and maintaining small regional herbaria as repositories of valuable biodiversity information. Likewise, this project also highlights the enduring value of training in floristics and taxonomy.

Estudios corológicos de plantas vasculares en la cuenca media del Tajo

Se ha realizado un estudio de la distribución de plantas vasculares en un territorio situado entre las provincias de Cuenca, Guadalajara, Madrid y Toledo (España). El territorio estudiado está en la Submeseta Sur de la península ibérica, al sur del Sistema Central, norte de los Montes de Toledo y oeste del Sistema Ibérico, en zonas sedimentarias con poco relieve y clima mediterráneo, con grandes contrastes de temperatura y precipitaciones muy irregulares. Coincide con las regiones naturales llamadas: “Alcarrias”, “Campiñas de Madrid y Guadalajara” y “Vegas de los ríos de la Cuenca del Tajo”. Es lo que he llamado Cuenca Media del Tajo. En una primera fase se ha estudiado la flora regional para adquirir conocimientos previos mediante las consultas bibliográficas y de herbarios, se ha contado con bases de datos disponibles para MA, MACB, MAF, JACA, AH, ABH, VAL, SALA y EMMA. Se han revisado las aportaciones propias que en los últimos años he realizado en el territorio en relación a los temas tratados en la tesis. El trabajo de campo ha consistido en la realización de inventarios de presencia de flora. Ha sido muy importante la tarea herborizadora para llegar a la correcta identificación de las especies colectadas en los inventarios. De esta forma el autor ha confeccionado un herbario propio JML que en el territorio muestreado ha reunido cerca de 15000 números en las cuatro provincias estudiadas. Se ha hecho un muestreo sistemático del territorio con unos 6000 listados de plantas. Se ha tomado como unidad de muestreo la cuadrícula de UTM de 1 km de lado incluida como una centésima parte de la cuadrícula de UTM de 10 km. Se han seguido criterios para uniformizar el muestreo. Se ha apuntado el tiempo empleado y la superficie muestreada estimada en cada toma de datos. El criterio mínimo que tienen que cumplir todas las cuadrículas en el área estudiada ha sido que para cada cuadrícula de UTM de 5 km se han realizado al menos 5 inventarios en 5 cuadrículas diferentes de UTM de 1 km y al menos en una hora de tiempo. La unidad de comparación ha sido la cuadrícula UTM de 5 km. Se han informatizado los inventarios de campo, para ello se ha creado la base de datos TESIS en Microsoft office –Access-. Las principales tablas son LOCALIDAD, en la que se anotan las características del lugar muestreado y ESPECIES, que lista las especies de flora consideradas en las cuatro provincias del estudio. Por medio de formularios se han rellenado las tablas; destaca la tabla ESPECIE INVENTARIO que relaciona las tablas ESPECIES y LOCALIDAD; esta tabla cuenta en este momento con unos 165.000 registros. En la tabla ESPECIES_FPVI se visualizan las especies recopiladas. Se ha creado un indicador llamado FPVI “Flora permanentemente visible identificable” que consiste en atribuir a cada especie unos índices que nos permiten saber si una determinada planta se puede detectar en cualquier época del año. Los resultados presentados son: Creación de la base de datos TESIS. El Catálogo Florístico de la Cuenca Media del Tajo, que es el catálogo de la flora de las cuatro provincias desde el principio de la sistemática hasta las Saxifragáceas. En total se han recopilado 1028 taxones distribuidos en 77 familias. Se ha calculado el índice FPVI, para las especies del catálogo. La finalidad para la que se ha diseñado este índice es para poder comparar territorios. Para el desarrollo de ambos resultados ha sido fundamental el desarrollo de la tabla ESPECIES_PVI de la base de datos TESIS. En la tabla ESPECIES_PVI se han apuntado las características ecológicas y se revisa la información bibliográfica disponible para cada especie; las principales fuentes de información consultadas han sido Flora iberica, el proyecto “Anthos” y las bases de datos de los herbarios. Se ha apuntado sí se ha visto, sí está protegida o sí en un endemismo. Otros resultados son: la localización de las cuadrículas de UTM de 10 km, con mayor número de endemismos o especies singulares, con mayor valor botánico. Se ha realizado un par de ejemplos de estudios de autoecología de especie, en concreto Teucrium pumilum y Clematis recta. Se han confeccionando salidas cartográficas de distribución de especies. Se ha elaborado el herbario JML. Se ha presentado una sencilla herramienta para incluir inventarios florísticos, citas corológicas, consultas de autoecología o etiquetado de pliegos de herbario. Como colofón, se ha colaborado para desarrollar una aplicación informática de visualización, análisis y estudio de la distribución de taxones vegetales, que ha utilizado como datos de partida un porcentaje importante de los obtenidos para esta tesis. ABSTRACT I have made a study of the distribution of vascular plants in a territory located between the provinces of Cuenca, Guadalajara, Madrid and Toledo (Spain). The studied area is in the “Submeseta” South of the Iberian Peninsula, south of the Central System, north of the Montes de Toledo and west of the Iberian System, in sedimentary areas with little relief and Mediterranean climate, with big temperature contrasts and irregular rainfall. Coincides with the natural regions called "Alcarrias", "countryside of Madrid and Guadalajara" and “Vegas River Tagus Basin”. This is what I have called Middle Tagus Basin. In a first step we have studied the regional flora to acquire prior knowledge through the literature and herbaria consultations, it has had available databases for MA, MACB, MAF, JACA, AH, ABH, VAL, SALA and EMMA herbaria. The contributions I have made in the last years in the territory in relation to the topics discussed in the thesis have been revised. The field work consisted of conducting inventories presence of flora. Botanize was a very important task to get to the correct identification of the species collected in inventories. In this way the author has made his own herbarium JML in the sampled area has met at least 15000 samples in the four studied provinces. There has been a systematic sampling of the territory with nearly 6,000 listings of plants. Was taken as the sampling unit grid UTM 1 km side included as a hundredth of the UTM grid of 10 km from side. Criteria have been taken to standardize the sampling. Data were taken of the time spent and the estimated sampled surface. The minimum criteria they have to meet all the grids in the study area has been that for each UTM grid of 5 km have been made at least 5 stocks in 5 different grids UTM 1 km and at least one hour of time. The unit of comparison was the UTM grid of 5 km. I have computerized inventories of field, for it was created a database in Access- Microsoft office -TESIS. The main tables are LOCALIDAD, with caracteristics of the sampled location and ESPECIES, which lists the plant species considered in the four provinces of the study, is. Through forms I filled in the tables; highlights ESPECIE INVENTARIO table that relates the tables ESPECIES and LOCALIDAD, this table is counted at the moment with about 165,000 records. The table ESPECIES FPVI visualizes all recollected species. We have created an indicator called FPVI "Flora permanently visible identifiable" that attributes to each species indices that allow us to know whether a given plant can be detected in any season. The results presented are: Creating data base TESIS. The Floristic Books Middle Tagus Basin, which is a catalog of the flora of the four provinces since the beginning of the systematic until Saxifragaceae. In total 1028 collected taxa in 77 families. We calculated FPVI index for species catalog. The purpose for which this index designed is, to compare territories. For the development of both results, it was essential to develop the table ESPECIES_PVI TESIS data base. Table ESPECIES_PVI has signed the ecological characteristics and bibliographic information available for each species is revised; the main sources of information has been Flora iberica, the Anthos project databases of herbaria. Targeted species has been recorded, when seen, protected or endemism. Have also been located UTM grids of 10 km, with the largest number of endemic or unique species and more botanical value. There have been a couple of species autecology studies, namely Teucrium pumilum and Clematis recta, as an example of this type of study. They have been putting together maps of species distribution. We made herbarium JML. I have presented a simple tool to include floristic inventories, chorological appointments, consultations or to tag autoecology herbarium specimens. To cap it has worked to develop a computer application for visualization, analysis and study of the distribution of plant taxa, which has used as input data a significant percentage of those obtained for this thesis.

Biosystematics of the Genus Andryala L. (Asteraceae)

Andryala (Asteraceae: Cichorieae) is a little-known Mediterranean-Macaronesian genus whose taxonomy is much in need of revision. The aim of the present biosystematic study was to elucidate species relationships within this genus based on morphological and molecular data. In this study several taxa are recognised: 17 species, 14 subspecies, and 3 hybrids. Among these, 5 species are Macaronesian endemics (A. glandulosa, A. sparsiflora, A. crithmifolia Aiton, A. pinnatifida, and A. perezii), 4 species are Northwest African endemics (A. mogadorensis, A. maroccana, A. chevallieri, and A. nigricans) and one species is endemic to Romania (A. laevitomentosa). Historical background regarding taxonomic delimitation in the genus is addressed from Linnaean to present day concepts, as well as the origin of the name Andryala. The origin of Asteraceae and the systematic position of Andryala is shortly summarised. The morphological study was based on a bibliographic review and the revision of 1066 specimens of 13 herbaria as well as additional material collected during fieldwork. The variability of the morphological characters of the genus, including both vegetative taxonomic characters (root, stem, leaf and indumentum characters) and reproductive ones (inflorescence, floret, fruit and pappus characters), is assessed. Numerical analysis of the morphological data was performed using different similarity or dissimilarity measures and coefficients, as well as ordination and clustering methods. Results support the segregation of the recognised taxa and the congruence of the several analyses in the separation of the recognised taxa (using quantitative, binary or multi-state characters). The proposed taxonomy for Andryala includes a new infra-generic classification, new taxa and new combinations and ranks, typifications and diagnostic keys (one for the species and several for subspecies). For each taxon a list of synonyms, typification comments and a detailed description are provided, just as comments on taxonomy and nomenclature, and a brief discussion on karyology. Additionally, information on ecology and conservation status as well as on distribution and a list of studied material are also presented. Phylogenetic analyses based on different nuclear and chloroplast DNA markers, using Bayesian and maximum parsimony methods of inference, were performed. Results support three main lineages: separate ones for the relict species A. agardhii and A. laevitomentosa and a third including the majority of the Andryala species that underwent a relatively rapid and recent speciation. They also suggest a single colonization event of Madeira and the Canary Islands from the Mediterranean region, followed by insular speciation. Biogeography and speciation within the genus are briefly discussed, including a proposal for the centre of origin of the genus and possible dispersal routes.
