Contribución al conocimiento de la brioflora del extremo suroeste de la Comunidad de Madrid

We present a list of 91 bryophytes (74 mosses, 16 liverworts and 1 hornwort) from the area of Cadalso de los Vidrios in the south-western tip of Madrid province. Eleven bryophytes are new records for the province, the occurrence of the liverwort Exormotheca welwitschii, for which some chorological comments are included, is especially outstanding.
