266 Botanical Notices from Spain. 
Barkhausia albida, Xeranthemum erectum, Presl; and on loose strong 
soil on the steep acclivity, over which the road from Canillas to this 
rock ascends, Cistus monspeliensis, L., C. crispus, L., Helianthemum ori- 
ganifolium, P., H. glaucum, P. var. suffruticosum, Boiss., H. hirtum,P., 
Passerina Tartonraira, Thymus longiflorus, Th. Mastichina, L., An- 
thyllis tejedensis, Chasmone argentea, Biscutella sacatilis, Boiss., and 
others. In the drift-sands of the lower alpine region, above the 
Cerro la Matanza, occurred rarely the Centaurea 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 grasses 
of the genera Festuca and Bromus, an erect form of Linaria origani- 
folia, DC., Galium verticillatum, Danth., Filago arvensis, L. B. 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 blossom Alyssum alpestre,L., A.calycinum, 
L., A. montanum, L., a. atlanticum, Desf. and B. vulgare, Iberis nana, 
All., Draba hispanica, Boiss., Onosma echioides, L., Bunium Macuca, 
Boiss., Genista aspalathoides, DC., (3. confertior, Boiss., Erodium tri- 
chomanefolium, L’ Hérit., Senecio minutus, DC., the rare Vella spinosa, 
Boiss., Hrysimum canescens, Rth., and Ranunculus graminifolius (. 
luzulefolius, Boiss., in great plenty, more rarely Callipeltis Cucullaria, 
DC., and Valerianella hamata, DC. On rocks on the summit I found 
Valeriana tuberosa, Saxifraga 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., 
Sisymbrium laxiflorum, Boiss., Fritillaria messanensis, Raf., Cerasus 
prostrata, DC., in flower, Centaurea montana, L., Paonia coriacea, 
Boiss., with buds, and the remarkable white-blossomed Geum hete- 
rocarpum, Boiss. On sandy places flowered Androsace maxima, L., 
Veronica precox, All., Myosotis stricta, Lk., Lithospermum incrassa- 
tum, Guss., Arabis auriculata, Lam., and other alpine plants, and in
