Edit. Universidad Complutense 1993 252 N. Ma/cos Samaniego & P. Navarro García INTRODUCTION The present study is the resul! of several herborizations made in the Toledo Mountains (Toledo). Of every taxon we indicate the number of the herbarium, of the Department of Biolo- gía Vegetal 1, Facultad de Biología, Madrid (MACH) and the UTM coordinates, on squares of ten km per side. Alliaria petiolata (MB.) Cavara & Grande. Tot.eoo: San Pablo de los Montes, 30SUi8577. 24-IV-1991, 980 m, P. Nava//o & N. Mar- ‘-os, MACH 41922. In spite of being a frequent species in the province, at present we have only the next refe- rences: VELASCO-NEGUERUELA (1978: 224) names it for the Toledo mountains, and Castillo (1991: 57). Sax¡fraga dichotoma Sternb. subsp. albarracinensis (Pau) DA. Webb. ToLEDO: San Pablo de los Montes, 305Ui8476, 24-IV-91, 1020 m, P. Nava//o & N. Mar- <os. MACH 41923. Ii is comparatively abundant in the perennial pastures of the rnountain areas. There are few testimonies in Toledo province. This is probably due to its confusion with the typical subspe- cíes. At the MAF herbarium there are two reeords for the locations of Nambroca and Almona- cid (110610 and 11(1611). Potentilla erecta (L.) Ráuschel. ToLEDo: Los Navalucillos, 305UJ5880, 850 m, 8-VIII-1987, N. Ma,cos & J. Matute, MACH 41924. SANCHEZ MATA, CAvIlAN & ECHEVARRíA (1990: 46) point out the searce of this taxon in the Luso-Extremadurense province. and establishing upon the base of their herborizations and on the relerences of other botanists, they mention its presence in Ciudad Real, Cáceres and iaén provinees. The speeimens herborized in the quagmire of the Chorro strcam attest tlie brief description for Toledo provinee, of VELASCO-NEGUERUELA, MARCOS SAMANIEGO & CEREZO (1989: 49). Rosa arvensis Hudson. ToLvoo: San Pablo de los Montes, 305UJ8476, 1080 m, 24-VI-1991. P. Navarro & N. Ma,cos, MACH 41257. It is a creeping and decumbent shrub that appears dispersed in the north and centre of the Iberian Peninsula. According to the bibliography and herbariums consulted, the location appor- ted repíesenis an important chorologie innovation for the CS peninsular. At the MAF herba- ríum wiIh number 87408. there is an exemplar herborized by Rivas Goday, Rivas-Martínez & Ladero at Montemayor del Río (Salamanca) and it is classified as Roscz ar’-e/’sis Hudson var. arIensls. GUILLÉN & RICO (1986: 161)) consider itas an innovation forthe western Central System at Montemayor del Río distuict (Salamanca). This is Ihe nearest location to ours. Vicioso (1964: 27) distinguishes among others the var. a/me/Isis in both Castiles. It corres- ponds to the taxon we have herborized at San Pablo de los Montes. Vieja hirsuta (L.) S.F. Cray. Tot.Eoo: San Pablo de los Montes, 305UJ8476, 1080 m, 24-VI-1991. E. Navarro & N. Ma,cos, MACH 41367. Cñorologíc Ccmnníhurions tú rIce Tc,ledo Mountaíns flora 253 It appears in Ihe bushes of the supramediterranean Quercus pyrenaiea forest [So/hotormi- nalis.Quercetum py/e/maic.-ae, (Rivas Goday, 1954) Rivas-Martínez 1987]. Though we do not know any referenee for tbis taxon in the Toledo province; there is a record at the MAF herba- rium from San Román de los Montes (112940). Pinguicula lusitanica L. TOLEDO: Los Navalucillos, 30SUi5880, 850 m, 2-VII-1990. C Mateas & N. Marcos, MACI3 41365. It is very abundaní in the hygrophyllous heaths (Ge,iisto anglicae-Eric.etum tetralicis Rivas Martínez 1979). which gíow op al the Chorro stream. It is a novelíy to Ihe Toledo flora. Festuca dtírando¡ Clauson subsp. livida (Hack.) Rivas Ponce & Cebolla. ToLEOO: San Pablo de los Montes, 30SUi8476, 4080 m, 24-Vl-1991, P Navarro & N. Marcos, MACH 41366. According tú the intraspecific discernments of Cebolla & Rivas Ponce (1990: 19) for Fes- tuca dura/,doi, Ihe exemplar herborized at San Pablo de los Montes corresponds lo the subsp. Inicia var. livida. We do no! know any previous reference for the south-centre of Ihe Iberian Peninsula, though Muñoz & al. (1991: 36) mention Ihe presence of Festuca durandoi in Villuercas-Ibor, withotít an specific taxonomic category. Tbe mentioned point must be added to CEBollA & RIVAS PONCE (1991: 256) map.
