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 Cynarahorrida, 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 ChenopodiacecE. 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. hispanicuSy 

 Notobasis syriaca, Silyhum Marianum, Centaurea Calcitrapa, Datura 

 Stramonium, Atractylis gummifera, L., and rare Verbena suplna 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 gray wacke 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 Piddra 

 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 oi Salsolacea, as Salsola 

 KaU,Ij., S. sativa, L., Salicornia fruticosa, h., 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 Atri- 

 plex Halimus, L., with other ChenopodiacecE. Huelva, 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.
