428 Botanical Notices from Spain. 
L., was now in flower in great plenty, wholly covering large tracts 
of land, and in the oak-woods grew luxuriantly Cynara horrida, and 
C. humilis, DC., very frequent. The last occur quite as numerous 
in the plains of the Guadalquivir, of which I will now say a few 
words. The banks of the Guadalquivir, from Andujar to Seville and 
further down, are for the most part lined with Tamarix gallica, L., 
Ricinus communis, L., Xanthium spinosum, L., X. Strumarium, L., 
and various Chenopodiacee. At Montoro and Cordoba, Salsola 
rosacea occurs plentifully; and at Montoro and Seville, here and 
there, Vitex Agnus-castus,L. The following plants are common in 
this flat land: Ammi Visnaga, L., Scolymus maculatus, Sc. hispanicus, 
Notobasis syriaca, Silybum Marianum, Centaurea Calcitrapa, Datura 
Stramonium, Atractylis gummifera, L., and rare Verbena supina and 
Heliotropium supinum. In the environs of Cordoba, at the foot of 
the Sierra Morena, grow luxuriantly and in tolerable abundance 
Paliurus australis, L., Asparagus horridus, L., and, on the contrary, 
rare, Anagallis verticillata, All. 
The graywacke formation of the Sierra Morena approaches within 
four miles of the coast in the south-western part of the province of 
Huelva, where a very intersected low hilly land, consisting of lime- 
stone debris, breccia and gravel overlies it, covering the coast from 
the mouth of the Guadiana as far as the mouth of the Rio Piédra 
at the little town of Cartaya, and is tolerably thickly wooded with 
pines (Pinus Pinea). In its underwood occurs Cistus ladaniferus, 
still very frequent, and also great quantities of Ulex genistoides, Brot., 
Calluna vulgaris, and a leafless prickly Genista. Pine-forests border 
this hilly land, which include the sandy coast of Cartaya up to the 
mouth of the Guadalquivir, and, as I before observed, descend far 
toward the coast of the province of Cadiz eastwards. The banks of 
the Guadiana, both Spanish and Portuguese, and the coast of the 
mouth of this noble stream as far as Huelva, are bordered with im- 
mense marismas or morasses, which have the same vegetation as the 
before-described morasses of the Isla de Leon and of Chiclana, and 
whose plants were now partly in flower. The chief portion of this 
saline marshy vegetation consists of a number of Salsolacee, as Salsola 
Kali, L., S. sativa, L., Salicornia fruticosa, L., and others; more- 
over, Obione portulacoides, Moq., Frankenia thymifolia, and espe- 
cially a large shrubby Statice with fleshy lanceolate leaves and red 
flowers, and a Senecio with fleshy cylindrical leaves. Everywhere on 
the hedges and walls around Agamonte and Huelva blossomed Aéri+ 
plex Halimus, L., with other Chenopodiacee. WHuelva, the chief 
- town of the province, lies on a tongue of land between two arms of 
the sea, stretching inland for several miles, at the foot of a height 
consisting of mere loam and sand, on which Salsola microphylla, Cav., 
occurs very plentifully. The banks of these two arms of the sea are 
also occupied by immense morasses, which present the same vege- 
gation as the before-described marismas. 
On the 10th of October I left Huelva and the next day reached 
Seville, whither the road leads through an uninterrupted lowland, 
which in part is extremely well cultivated, especially from Palma,
