region extends, is almost entirely covered with thorny shrubs, of the 

 Berberis vulgaris, L., var. australis, Cratcegus granatensis, Boiss., 

 Prunus Ramburei, Boiss., Rhamnus infectorius, L., and Cerasus pro- 

 strata, DeC, which forms small and very entangled and stiiF shrubs, 

 from half a foot to three foot high, and is found as far as the highest 

 summit of the Dornajo, where, creeping up the loose rocks, it covers 

 them like a kind of moss. In very isolated spots, under the thorny 

 shrub, grows the beautiful Lonicera splendida, Boiss., which is di- 

 stinguished from L. Capri/olium, L., and L. implexa, Ait. (to which it 

 is nearest allied), partly by the many-flowered racemes, and partly by 

 the white dust on the under side of the evergreen leaves and of the 

 young branches. The berries are oval, large and orange-coloured. 

 L. etrusca, Santi, is found in the neighbourhood of brooks, in shady 

 bushes, generally in company with the Clematis Flammula, L. On 

 the banks of the Monachi] I found frequent the Rumex pulcher, L., 

 Delphinium pentagynum, Desf., Thalictrum glaucum, Desf., Nepeta 

 granatensis, 13oiss., Junci, Euphorbi(£, and two Reseda) in the upper 

 part of the valley, Heracleum granatense, Boiss., with Cochlearia 

 glastifolia, L., and Aspidium nevadense, Boiss. The shady clefts of 

 the rocks are decorated with patches of the delicate and fragile 

 Linaria villosa, DeC, and L. verticillata, Boiss., along with Hiera- 

 cium amplexicaule, L. ; whilst on the sunny limestone and marble 

 rocks of the southern declivity are found the pretty Campanula Lceff- 

 lingii, Brot., in company with Putoria calabrica, T., several Teucria 

 and others. 



Among those portions of the limestone alps which are the most 

 celebrated as producing the rarest plants, the Dornajo and Cerro 

 Trevenque occupy undoubtedly the first place. The latter, above 

 7000 feet high, presents a huge j^yramid of rock, and is seldom as- 

 cended by the inhabitants of the mountain on account of its extra- 

 ordinary steepness. I ascended it on the 7th of August, accompa- 

 nied by my servant. We first followed the steep bed of a rivulet 

 filled with blocks of marble, which contributes the waters of its little 

 stream to the Monachil, and soon saw ourselves surrounded with 

 some isolated pines, which announced the Cartejuela. In this copse- 

 wood, which is scarcely to be called thick, as well as in the ascent, 

 I found frequent the tender Reutera gracilis, Boiss., of the habitus 

 of an Asperula, as well as the Pceonia coriacea, Boiss., which is not 

 rare on the Dehesa, S. Geronimo, and even around the Cortijo. 

 When we had reached the plateau, about 6000 feet, I first ascended 

 the Cerro Tesoro, lying on the right, and of a not much greater ele- 

 vation, whose entire northern declivity is covered with Anthyllis 

 erinacea (common throughout the whole limestone alps) and a thorny 

 Astragalus. Besides the Passerina Tartouraira, L., which is here 

 very small-leaved, Anthyllis tejedensis, Boiss., and Ononis cephalotus, 

 Boiss., the vegetation consists of the same plants as I had already 

 found on the Dornajo. The Odontites longiflora, Webb, is found, as 

 well as on the Dornajo, from the base to the summit ; in the clefts of 

 the rocks grow on both mountains Potentilla caulescens, L., forming 

 hard thick beds, in company with Arenaria Armeriastrum, Boiss.,
