Nuevas aportaciones a la flora de Leon.

New contributions to the flora of Leon

INTRODUCTION

This paper contains the first reports of nine taxa for the province of Leon, and the extension of the geographic distribution of these species in the region. New records of range extensions are recorded for some plant taxa.

The voucher specimens collected by us and reported here include the collection location--with its municipality in parentheses--, UTM coordinates, elevation, habitat, collection date, number assigned in the University of Leon Herbarium collection (LEB) and the collectors name. For the voucher specimens not collected by us, we include the information provided on their label.

Taxa names follow Flora Iberica (CASTROVIEJO & al, 1986-2013) and Flora Europaea (TUTIN & al., 1968-1980, 1993), except in some cases where we have followed the criteria of taxonomic specialists: Phelipanche (CARLON & al., 2005), Tolpis (TALAVERA, 1980) and Klasea (CANTO, 1984, 2012, 2013). Other reference works for the area are: DEL EGIDO & PUENTE (2011), DEL EGIDO & al. (2007, 2012b).

RESULTS AND DICUSSION

Aira cupaniana Guss.

Leon: Between Puente de Domingo Florez and Vega de Yeres (Puente de Domingo Florez), 29TPG7998, 430 m, grasslands, SE, 14.04.2003, L. Gonzalez de Paz, LEB 99389. Balouta River valley in Salas de la Ribera (Puente de Domingo Florez), 29TPH8001, 470 m, grasslands, NW, 29.04.2004, L. Gonzalez de Paz, LEB 99388. Between La Bana and Silvan (Encinedo), 29TPG9285, 1500 m, grasslands, S-SW, 12.06.2004, L. Gonzalez de Paz, LEB 97780.

Although this species has been reported for the nearby province of Orense (LAINZ, 1974: 23; GIMENEZ DE AZCARATE & al., 1990: 11; GIMENEZ DE AZCARATE & AMIGO, 1996: 21), we have not found bibliographic references of it or herbarium vouchers collected in our province. Herein, we report the first voucher specimen data confirming its occurrence in Leon.

Brachypodium retusum P.Beauv.

(= Brachypodium ramosum Roem. & Schult.)

Leon: Near the peak Cruz de la Pena (Benuza), 29TPH9003, 1342 m, base-rich grasslands, SE, 11.07.2007, L. Gonzalez de Paz, LEB 99261.

It has been reported from Los Barrios de Luna (LLAMAS & ACEDO, 1997: 141) and Corsalines valley (LENCE PAZ, 2001: 86), a third additional record for Leon is provided increasing the range of this species to the southwest of Leon.

Carex depauperata Curtis ex With.

Leon: Between Benuza and Yebra (Benuza), 29TPG896981, 700 m, oak forest, NE, 17.05.2005, L. Gonzalez de Paz, LEB 96895. Santa Elena chapel pathways (Benuza), 29TPG9392, 982 m, oak forest, NW, 11.06.2006, L. Gonzalez de Paz, LEB 96894.

Reports of Carex depauperata in Leon are documented in VICIOSO (1959: 154) but without a precise locality. MOLINA & al. (2006: 31) provided records from El Bierzo (Molinaseca, Toreno and Bouzas).

Carex furva Webb

Leon: Cadabal River glacial cirque (Encinedo), 29TPG8777, 2022 m, chionophilous matgrass communities, bogs and alpine grasslands, 14.08.2006, L. Gonzalez de Paz, LEB 96628.

LUCENO (1986: 437) provides the only known report from Leon, collected in Pena Trevinca. Our citation adds a second record.

We have found citations from the Luna River valley (ROMERO RODRIGUEZ, 1983: 139), Vegabano (CARBO & al., 1987: 73) and La Pola de Gordon (PEREZ MORALES, 1988: 203). We provide additional localities for this sedge.

Carex sylvatica Huds. subsp. sylvatica

Leon: Cabrera River in Llamas de Cabrera (Benuza), 29TPG9497, 560 m, hazel forest, NW, 11.08.2009, L. Gonzalez de Paz, LEB 103041.

Although this species is widely distributed in the north of Leon, it has not been previously reported in the southwest. This record extends the range of this taxon in southwestern territories of Leon.

Centaurium maritimum (L.) Fritsch

Leon: Limestones in Ferradillo (Benuza), 29TPH9003, 1389 m, base-rich grasslands, S, 11.07.2007, L. Gonzalez de Paz, LEB 94753.

PEREZ CARRO & al. (1985: 139) recorded it from Villadangos del Paramo and AEDO & al. (2001: 26) from Cabanas Raras. This is the third record for Leon. It has been also cited in Orense (LAINZ, 1971: 18; MORLA, 1982: 394) and Zamora (GARCIA RIO & NAVARRO ANDRES, 1994: 56).

Cheilanthes acrostica (Balb.) Tod.

Leon: Penarrubia, Portela del Cuerno (Carucedo), 29TPH8003, 860 m, limestone fisures, S, 15.04.2003, L. Gonzalez de Paz, LEB 95362.

Rubiana, dolomite fisures, S, 11.06.1983, F.J. Perez Carro & M.P. Fernandez Areces, LEB 23279. Rubiana, dolomite fisures, S, 11.06.1983, F.J. Perez Carro & M.P. Fernandez, Areces, LEB 29231.

This taxon has only been cited from Leon by Lange (1860: 22 sub Cheilanthes odora Sw.) although Aedo & al. (2001: 9) thought it should be Cheilantes tinaei, because is abundant in the area. We include under this species some specimes determined as Cheilanthes pteridioides (Reichard) C.Chr. after revising LEB. Cheilanthes acrostica has not without glandular hairs under the pinnae and the pseudoindusium is frimbriate.

This Mexican and Central American native has not been previously reported in Leon, being our record the first for the province. Different works on allochthonous Iberian or Castilla y Leon flora do not include Leon within the range of this taxon (SANZ ELORZA & al., 2004: 150-151; ACEDO & Llamas, 2006; SANZ ELORZA & al, 2008: 126) but it has been cited for Salamanca, Zamora and Valladolid (SANZ ELORZA & GONZALEZ BERNARDO, 2007: 108).
