Abstract

FREIRE, Susana E. et al. Epidermal characteristics of toxic plants for cattle from the Salado River basin (Buenos Aires, Argentina). Bol. Soc. Argent. Bot. [online]. 2005, vol.40, n.3-4, pp.241-281. ISSN 1851-2372.

One hundred and eighty species belonging to 41 families inhabiting the Salado River Basin of the province of Buenos Aires (Argentina) were previously reported to be toxic for cattle. The purpose of this study was to provide a tool to distinguish the taxa when the plant material is desintegrated. In this way, an approach to the identification of these taxa through leaf epidermal features (anticlinal epidermal cell wall patterns, cuticular ornamentation, stomata, and hair types) is performed. A key to the 180 species as well as illustrations of diagnostic characters are given.

Keywords : Buenos Aires; Salado River Basin; Toxic plants; Anatomy; Epidermal characters; Stomata; Hairs; Dicotyledons; Monocotyledons.
