Abstract
Bariego Hernández, P.; Delgado Sánchez, L. & Santos Vicente, M. 2004. Contribution to the knowledge of the Duero basin (Spain) pteridophytic flora. Bot. Complut. 28: 57-59. New references are given for seven pteridophytes in Zamora and Valladolid province. In all cases are rare taxa in the Spanish Duero basin area. Ophioglossum vulgatum L. and Thelypteris palustris Schott are referenced here for the first time in Valladolid province. Four of them, Lycopodiella inundata (L.) J. Holub, Marsilea strigosa Willd., Pilularia globulifera L. and Pilularia minuta Durieu, have been cataloged as `threatened' in the Spanish Red List and other legal regulations about threatened Spanish vascular flora.Downloads
