Abstract

LOPEZ-TIRADO, Javier. Updating the distribution of the genus Isoetes (Isoetaceae) in southern Spain (Córdoba, Andalusia). Caldasia [online]. 2022, vol.44, n.1, pp.1-7.  Epub Apr 27, 2022. ISSN 0366-5232.  https://doi.org/10.15446/caldasia.v44n1.91416.

Isoetes belong to the Class Lycopodiopsida (lycophytes). The genus is generally underrepresented in collections due to a lack of diagnostic characteristics and inconspicuous appearance. The current distribution of Isoetes within Córdoba province is provided in a 1 km2 grid from several sources: (i) herbaria sheets from COA, COFC, MGC, SEV, GDA, and GDAC, (ii) 107 new observations since 2012, and (iii) records from literature and databases. Nine herbaria sheets were correctly determined. The most frequent species was I. histrix, well represented in the northern half of the province. Isoetes durieui, I. longíssima, and I. delilei were much less common. The present work aims to update the current distribution of this genus in Córdoba province (Spain), in which several species are classified as threatened.

Keywords : Andalusia; Córdoba; Lycopodiopsida; Spain.
