CARRASCO, M. A. & MARTÍN-BLANCO, C. J. 2002. Update of the MACB type collection, II. Bot. Complutensis, 26: 59-62. In this paper the Type collection of the MACB Herbarium is update. We indicate the category of seven names (Holotypus, Isotypus Isolectotypus or Sintypus), as well as the herbariums with other type specimens of the same taxa. The new Typus are: 2 Holotypus, 4 Isotypus, 1 Isolectotypus and 2 Sintypus.

MEDINA, L., GARCÍA RÍO, R. & DRAPER, D. 2002. Notes on Ciudad Real aquatic flora. Bot. Complutensis 26: 53-58. Four aquatic plants, all of them rare or threathened species in Castilla-La Mancha, have been collected in Ciudad Real province. Marsilea batardae is recorded for the second time for the province and the distribution area of Butomus umbellatus, Hydrocotyle vulgaris and Marsilea strigosa is extended.

RODRÍGUEZ RAJO, F.J., SEIJO COELLO, M.C. & JATO RODRÍGUEZ, M.V. 2002. Study of the main phytopatogenic level’s in order to optimize the harvest of Vitis vinifera in Valdeorras, Ourense (1998). Bot. Complutensis 26: 121-135. Estudio de los niveles de los principales fitopatógenos para la optimización de cosechas de Vitis vinifera en Valdeorras (1998). The peculiar climatological characteristics of Galicia favours the appearance in the vineyards of the diseases produced by fungus as grey mould, powdery mildew or downy mildew that endangers the grape production provoking millionaire losses. With the aim to know the level of fungal spores, it was placed an Hirst type volumetric sampler in a vineyard of Ourense. Of the tree pathogenic fungus studied, it was found important quantities of Botritys fungal spores, that amount a total of 12303 spores. The moment of the day with highest concentrations are the 19-20 hours. The total values registered by Uncinula and Plasmopara were minor (1456 y 242 spores respectively). Dew temperature for Botrytis cinerea, maximum temperature for Uncinula necator and external humidity for Plasmopara viticola, were the meteorological variables that exert the highest positive influence in the spore concentrations of the vineyard. Finally the models attempted for the prediction of the infections that takes into account the meteorological variables in addition with the quantity of pathogenic spores existing, have the best prediction capacity.

Although the biogeographic schemes proposed for Mexico are based on different criteria (geographic, paleontological, faunistic or floristic), their authors implicitly acknowledge that the units recognized actually represent historical entities. The development of panbiogeography and cladistic biogeography has challenged traditional classifications, by showing that some of these biogeographic units did not represent natural units. Furthermore, there have been attempts to construct ecogeographic systems, based on the assumption that biotic and abiotic factors constraint species distributions within definite areas. By synthesizing both biogeographic and ecological systems, we propose a new scheme for Mexico, where we recognize the following 14 provinces: California (northern portion of the Baja California peninsula, from Sierras of San Pedro Mártir and Juárez, extending northward along the Sierra Nevada into southwestern USA), Baja California (Baja California peninsula), Sonora (coastal areas in northwestern Mexico, from the northeastern portion of the Baja California peninsula to the Piaxtla river basin in southern Sinaloa), Mexican Plateau (central Mexico, in the states of Zacatecas, San Luis Potosí, Guanajuato, Chihuahua, Coahuila, Durango, and Nuevo Mexico, as well as small parts of Nuevo León, and Sonora, below 4,000 m altitude), Tamaulipas (coastal areas in the northern part of the Mexican Gulf, north of the Pánuco river basin), Sierra Madre Occidental (western Mexico, in the states of Chihuahua, Durango, Zacatecas, Sonora, Sinaloa, Nayarit, and Jalisco, above 1,000 m altitude), Sierra Madre Oriental (eastern Mexico, in the states of San Luis Potosí, Tamaulipas, Coahuila, Hidalgo, Nuevo León, Veracruz, Puebla, and Querétaro, above 1,500 m altitude), Transmexican Volcanic Belt (central Mexico, in the states of Guanajuato, Mexico, Distrito Federal, Jalisco, Michoacán, Puebla, Oaxaca, Tlaxcala, and Veracruz), Balsas Basin (central Mexico, in the states of Guerrero, Mexico, Jalisco, Michoacán, Morelos, Oaxaca, and Puebla, below 2,000 m altitude), Sierra Madre del Sur (south central Mexico, from southern Michoacán to Guerrero and Oaxaca, and part of Puebla, above 1,000 m altitude), Mexican Gulf (coast of the Mexican Gulf, in eastern Mexico, Belize, and northern Guatemala), Mexican Pacific Coast (western Mexico, in the Pacific coast of the states of Sinaloa, Nayarit, Colima, Jalisco, Michoacán, Guerrero, Oaxaca, and Chiapas), Yucatán Peninsula (Yucatán peninsula, in the states of Campeche, Yucatán, and Quintana Roo, below 200 m altitude), and Chiapas (southern Mexico, Guatemala, and Nicaragua, basically corresponding to the Sierra Madre de Chiapas, from 500 to 2,000 m altitude).
