Wisteria sinensis (Leguminosae) adventitious in Argentina: First record and expansion mechanisms

Wisteria sinensis (Leguminosae) adventitious in Argentina. First record and expansion mechanisms. This paper includes the first record of Wisteria sinensis (Leguminosae) adventitious in Argentina, observations on its mechanisms of expansion and its status in the context of the naturalization process.

Bignoniaceae adventicias en la Argentina: primera cita de Podranea ricasoliana y nuevos registros de Campsis radicans

Bignoniaceae adventitious in Argentina. First reference to Podranea ricasoliana, and new records of Campsis radicans. This paper includes the first reference to Podranea ricasoliana and new records of Campsis radicans (Bignoniaceae) for the adventitious Argentinean Flora. Also includes observations on the expansion mechanisms and the status into the naturalization process for P. ricasoliana, besides a key to differentiate the adventitious Bignoniaceae in Argentina.

Primera cita de Parthenocissus tricuspidata y nuevo registro de P. quinquefolia (Vitaceae) adventicias en la Argentina

First reference of Parthenocissus tricuspidata and new record of P. quinquefolia (Vitaceae) adventitious in Argentina. This paper includes two adventitious species of the genus Parthenocissus Planch. in Argentina: P. tricuspidata (Siebold & Zucc.) Planch. and P. quinquefolia (L.) Planch., both introduced as ornamentals. Descriptions, synonymy, iconography, distribution, common names, uses, keys and reference material are given. Also contains observations about its climb strategies, its expansion mechanisms, and its actual status in the context of naturalization process.

Listado comentado de las plantas vasculavasculares trepadoras y epifitas de la costa rioplatense del Partido de Quilmes (Buenos Aires, Argentina).

Commented list of the climbing and epiphytic vascular plants of the coast of the Rio de la Plata at Quilmes and Avellaneda district (Buenos Aires, Argentina). The present study includes the taxonomic richness by biological type of climbing and epiphytic plants of the coastof Quilmes district, with emphasis on the Municipal Reserve “Selva Marginal Quilmena”. A predominance of native species over exotic ones was found: 6 to 0 of epiphytes and 44 to 12 of climbers. The finding of Sicyos polyacanthus that maintains in the zone its southernmost population is highlighted. It is also relevant the presence of Pleopeltis minima, Araujia angustifolia and Philodendron undulatum that extended their distributions towards the south in recent times. These records, as well as those of several species of difficult discovery in the Rio de la Plata coast, accentuate the value of the area for biodiversity conservation. The varied taxonomic composition of the area could be explained in terms of the complex history of expansion/retraction pulses of altered areas and of spontaneous vegetation, with respect to the others, and the location of the studied area within the dispersal route of the Rio de la Plata fluvial system.
