the rocks of this range grew luxuriantly Sarcocapnos enneaphylios, 
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., Bupleurum gibraltaricum, L., Biscutella saxatilis, Boiss., and on 
the acclivities Plumbago europea, 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- 
balcén, 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 coccifera, Cistinee, &c., among which 
occur Leuzea conifera, Chamepeuce 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 ori- 
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 Jabalcén 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, Serratula flavescens, Poir., Arenaria Armeriastrum, Boiss., Cen- 
taurea granatensis, Boiss., Peonia 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., Pistorinia hispanica, DC., and various grasses. On rocks 
of the summit were seen Savifraga spathulata, and on the northern 
acclivity Anthyllis erinacea, Ptilotrichum spinosum, Salvia officinalis, 
and Odontites longiflora, Webb. 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 Huelma, 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,
