with Frankenia corymbosa, Desf. In other respects the vegetation 
had nothing peculiar. 
From Motril I ascended on the 15th of June the Sierra de Lujar, 
lying some miles to the eastward, a dolomite range of mountains 
more than 6500 feet high according to the measurement of Clemente, 
which runs parallel with the Sierra Nevada, from which it is sepa- 
rated by the deep valley of the Riode Orgiva. This range is joined 
on the east by the considerably lower and vine-clad Sierra de Con- 
traviesa, which forms the southern boundary of the eastern Alpu- 
jarras, and is divided by the valley of the Rio de Adu from the Sierra 
de Gador situated in the province of Almeria. In the hilly country 
lying between Motril and the Sierra de Lujar, Thymus capitatus, Lk., 
Hoffm., occurred in flower, and around Motril it covers large tracts; I 
also gathered here in corn-fields Reseda lanceolata, Lag., and on shady 
walls near the little village of Lagua a species of Scrophularia resem- 
bling S. crithmifolia, Boiss.,but differing from that, and probably anew 
species. The vegetation of the Sierra de Lujar is on the whole very 
similar to that of the Sierra Tejeda, but less rich in species. In the 
upper portion however occurred some interesting plants, which I had 
not before gathered, as Centaurea Boissieri, DC., Serratula pinnatifida, 
DC., Helianthemum canum, Dun., H. niloticum, P., Athionema sar- — 
_atile, R. Br., Thlaspi perfoliatum, L., and Arenaria grandiflora, L. 
Here grow, as in the Sierra Tejeda, Cerastium repens, Alyssum al- 
pestre and montanum (3. vulgare, Saxifraga spathulata, Draba hispa- 
nica, Vella spinosa, Ptilotrichum spinosum, Anthyllis erinacea and 
others in great numbers. ‘This mountain-range is in part wooded 
with Quercus Ilex, and from the foot to the summit occurs Aphyllan- 
thes monspel., L., which is wanting on the Sierra Tejeda, as well as 
in some places Callipeltts Cucullaria, DC., in great abundance. 
On the 16th of June I left Motril, and had the good fortune to 
find, upon limestone rocks in the neighbourhood of the little town of 
Velez de Benandalla, the hitherto little-known Lafuentea rotundifolia, 
Lag., a remarkable Personata, with very fragile thickly interlaced 
stalks, round fleshy curved leaves and dense naked heads of small 
yellowish white flowers resembling those of a Crucianella. In Velez 
I crossed the Guadalfeo, which was extremely swollen by the snow- 
water, in order to go a roundabout way through the Sierra de las 
Almijarras to Granada. This wild romantic limestone chain, which 
is partly wooded with Pinus Pinea, P. halepensis and P. Pinaster, as 
well as by Quercus Ilex and Qu. lusitanica a. faginea, rises scarcely 
to 5000 feet, and forms a half circle open toward the east, or more 
properly takes a horse-shoe shape. The centre of this extensive chain, 
west of the village of Guajar Alto, passes imperceptibly over to the 
Sierra Tejeda, and from hence a lofty southern mountain-chain 
stretches along the coast as far as the Guadalfeo, whilst a second 
lower chain goes parallel with the former and the western part of the 
Sierra Nevada, terminating in the country of Lanjaron, and forming 
the rocky wall on the right of the Rio Grande. The two chains are 
separated by a broad valley, which is watered by a rivulet and in 
part filled with hills: in this valley lie three villages, Guajar Fondo, 
aye
