42d Botanical Notices from Spain. 



the rocks of this range grew luxuriantly Sarcocapnos enneaphyllos, 

 DC, Teucrium pyrenaicum, L., var. granatense, Boiss., T. Polium, L., 

 T. capitatum, L., Silene velutina, Pourr., Chrysocome verticalis, Lag., 

 Inula montana, L., Galium verticillatum, Danth., Scabiosa tomentosa, 

 Cav., Bupleurumgihr altar icum, L., Biscutella saxatilis, Boiss., and on 

 the acclivities Plumbago europcea, L., Ballota hirsuta, DC, and Thymus 

 tenuiflorus, Boiss. The Sierra de Arenas is intersected by the Rio 

 de Campillos, which further on joins the river of Jaen. The left 

 rocky wall of this river consists of debris of laminar gypsum, and is 

 therefore covered with a salt vegetation, among which especially oc- 

 curs Ononis crassifolia, Duf., in abundance. Further down Balsa- 

 mita multifida, Clem., is very plentiful. 



From Jaen, where I stayed three days, I ascended the Cerro Ja- 

 balc6n, one of the highest summits of the Sierra, and convinced my- 

 self in this excursion of the great sterility of this mountain- chain. 

 The lower portion of it is covered with Lavandula Spica, Phlomis 

 purpurea. Ph. Lychnitis, Thymus tenuiflorus, Th. Mastichina, Teucrium 

 Polium, T. capitatum, Quercus cocci/era, Cistinece, &c., among which 

 occur Leuzea conifera, ChamcEpeuce hispanica, DC, Chrysocome verti- 

 calis, Ruta montana. Inula montana, Crambe filiformis, Scabiosa tomen- 

 tosa, Santolina rosmarinifolia. Mill., and Helichryson serotinum, Boiss. 

 On the rocks of the mountain-region grew luxuriantly Linaria 07'i- 

 ganifolia, DC, Silene velutina, Digitalis obscura, L., Teucrium pyre- 

 naicum, Helianthemum marifolium and Cerastium repens, L., which is 

 common on the northern acclivity of the Cerro Jabalcon up to the 

 summit. In the upper part of the mountain- chain a narrow-leaved 

 Iris was still flowering on grassy slopes, and I also found here off 

 flower, Serratulaflavescens, Poir., ArenariaArmeriastrum, Boiss., Cen- 

 taurea granatensis, Boiss., Pceonia lobata, Desf., Scorzonera hispanica, 

 L., Cirsium echinatum ; and on the upper face of the range Xeran- 

 themum erectum, Presl, Muscari comosum and racemosum, Silene 

 conica, L., Pistori?iia hispanica, DC, and various grasses. On rocks 

 of the summit were seen Saxifraga spathulata, and on the northern 

 acclivity Anthyllis erinacea, Ptilotrichum spinosum, Salvia officinalis, 

 and Odontites longiflor a, Wehh. On my way back I found by a spring 

 Lysimachia Ephemerum, L., and Hypericum Caprifolium, Boiss., and 

 finally on perpendicular and inaccessible walls of rocks in the neigh- 

 bourhood of Jaen some shrubs of Rhus Coriaria, L., in fruit. 



On the 25th of August I quitted Jaen, and went seven leagues 

 eastward to the town of Ubeda, which lies on the other side of the 

 Guadalquivir below the mouth of the Guadiana Menor. The way 

 thither leads over a hilly gypsum formation, completely destitute of 

 trees and water, which fills up the space between the river of Jaen, 

 the Guadalquivir, and the Sierra de Huelraa, and whose vegetation, 

 now almost wholly dried up, is similar to that of the gypsum basin 

 of Baza. Among other plants, Lygeum Spartum, Helianthemum squa- 

 matum, Stellera Passerina, Ammi Visnaga, Centaurea granatensis, C. 

 Calcitrapa, Catananche lutea, Cleonia lusitanica, Momordica Elaterium, 

 Crozophora tinctoria, Capparis spinosa, Atractylis cancellata, and a 

 number of thistles, for instance Scolymus hispanicus, Sc. maculatus,
