Barkhausia alhida, Xeranthemum erectum, Presl ; and on loose strong 

 soil on the steep acclivity, over v^^hich the road from Canillas to this 

 rock ascends, Cistus monspeliensis, L., C. crispus, L., Helianthemum ori^ 

 gani/olium. P., H. glaucum, P. var. suffruticosum, Boiss., H. hirtum,F.t 

 Passerina Tartonraira, Thymus longiflorus, Th. Mastichina, h., An- 

 thyllis tejedensis, Chasmone argentea, Biscutella saxatilis, Boiss., and 

 others. In the drift-sands of the lower alpine region, above the 

 Cerro la Matanza, occurred rarely the Centaur ea bombycina, Boiss., 

 peculiar to this mountain-range, a small elegant species with procum- 

 bent stalks, pinnate, white downy leaves and violet flowers, which 

 began to unfold its little heads of flowers ; also a beautiful purple 

 variety of Linaria tristis } in great abundance, and various gTasses 

 of the genera Festuca and Bromus, an erect form of Linaria origani- 

 folia, DC, Galium verticillatum, Danth., Filago arvensis, L. /3. La- 

 gopus, DC, Bunium Macuca, Boiss., and along the rock thick beds 

 of the shrubby Coronilla eriocarpa, Boiss., beginning to flower, — only 

 a few plants had already developed their peculiar white woolly pods. 

 From near the foot of the mountain-range up to the summit, the 

 pretty Armeria filicaulis, Boiss., is tolerably plentiful, which in the 

 upper alpine region forms small patches of turf with stems scarcely 

 a finger high, whilst in the lower parts it reaches a height of from 

 half a foot to a foot. 



From the Fuente la Gitana, a spring lying about 500 feet above 

 the Cerro la Matanza, the path winds zigzag upwards on the extra*" 

 ordinarily steep acclivity of the summit, covered almost wholly with 

 loose masses of rock. Here h\o&?>om.Alyssum alpestre,\j., A.calycinum, 

 h., A. montanum, L., a. atlanticum, Desf. and j3. vulgare, Iberis nana, 

 AIL, Draba hispanica, Boiss., Onosma echioides, L., Bunium Macuca,

 Boiss., Erysimum canescens, Rth., and Ranunculus graminifolius /3. 

 luzultefolius, Boiss., in great plenty, more rarely Callipeltis Cucullaria, 

 DC, and Valerianella hamata, DC On rocks on the summit I found 

 Valeriana tuberosa, Sawifraga spathulata, Desf., and Draba hispanica, 

 and moreover on the whole of the broad coomb Vella spinosa, Anthyllis 

 erinacea, Ptilotrichum spinosum and Arenaria erinacea, Boiss., the 

 last not yet in flower. The broad, gently rounded surface, of con- 

 siderable extent, forming the summit, descends toward the north 

 into a table- land filled with many hollows, in which there were still 

 large fields of snow, and which bears the name of Los Ventisqueros. 

 Here, at the edge of the melting snow, I again found Bulbocodium 

 vernum, as well as on the whole of the northern acclivity, of the sum- 

 mit the root leaves of the rare and remarkable Andryala Agardhii, 

 Boiss., and under low shrubs of Berberis vulgaris /3. australis, DC,
