Crónicas, reliquias, piedras legendarias y coronaciones en la Edad Media

La «Piedra del Destino», como muchas reliquias y antigüedades de la Edad Media, tuvo una larga historia, escrita por cronistas e historiadores. Una historia muy semejante a otras translationes de reliquias. La historia de la «Piedra del Destino» contiene ricos aspectos jurídicos, políticos y sacrales. Para comprenderlos es necesario analizar las crónicas, entendidas como textos históricos, que dan sentido a los rituales jurídicos y políticos de la Edad Media.

Canna tandilensis Ciciar. (Cannaceae-Zingiberales), a new species from Argentina.

Canna tandilensis is proposed as a species new to science. Plants grow wild terrestrial, in rocky places exposed to solar radiation forming dense colonies whose individuals of small to medium length, produce reduced inflorescences with large and few yellow to bright orange flowers and narrow and reflexed staminodes. The specific epithet refers to the city of Tandil at the south of Buenos Aires Province where the holotype comes from. It is related to other species having reduced inflorescences, narrow leaves and staminodes, and nectar guides in androecium pieces such as C. lineata. A detailed description of the new species is given, along with a study of the morphological vegetative and floral characters. These characters were compared with those from two other species C. glauca and C. lineata. According to these new evidences two groups of similar species of the genus are suggested. The number of species surveyed until now in Argentina rises to sixteen.

Ecología y fitosociologia del ecótono de dos jarales de Cistion laurilfolii de la Sierra de Guadarranma (España)

Se describe la subasociación Rosmarino-Cistetum ladaniferi cistetosum cyprii. que representa el ecótono entre Rosmarino-Cistetum ladaniferi y Santolino-Cistetum laurifolii. La ecología del nuevo sintaxon se ha estudiado seleccionando dos grupos de parcelas que comprenden representantes de las tres unidades fítosociológicas, y sobre las que se han efectuado medidas de temperatura y humedad edáficas bajo la cubierta vegetal a lo largo del año, así como de distintos aspectos microclimáticos a lo largo de un día tipo. El carácter de transición de la nueva subasociación ha quedado puesto de manifiesto tanto para el factor térmico como hídrico.

The duty of loyalty in the cooperative law. A comparative study

Among the duties of the government bodies’ members of the different entities, which are connected to the good government, the duty of loyalty must be underlined. This duty, derived from the good-faith duty, obliges to act in the interest of the entity in case of conflict of interest, and to subordinate one’s own interests, except when there is an authorisation. Loyalty duty is applicable both to managers, who must manage the entity’s interest, and to partners, according to the common purpose derived from the company contract. This duty, at the same time, includes some particular rules, referred to transparency, remuneration, prohibition of competition, self-contracting... This essay compares the regulation of the duty of loyalty and its realizations in the different Cooperative Laws in Spain, both referring to the managers and to the partners, comparing this, at the same time, with the regulation of these aspects in companies’ general legislation, an in the Spanish Corporate Enterprises Act in particular, in order to obtain a general view of the issue, a necessary basis to go more deeply into it, and suggesting some preliminary conclusions or assessments.
