18G2.] BOTANY OF SPAIN. 39 



never saw even an approach elsewhere. The species must be 

 numerous, but I regret my inability to record them. The fatigue 

 of the journey, the multitude of other plants to determine and 

 put into paper, and the difficulty of dealing with this genus with- 

 out the fruit and without proper books, deterred me from the 

 attempt. Rosa tonieniosa, or some species near to it, appeared 

 to be one, and another resembled, in the appearance of its stem, 

 R. spinosissima, but with much larger flowers; in fact, as I have 

 already mentioned, the size of the Roses was quite as remark- 

 able as their profuse abundance. 



Saxifraga Aizoon, now in full floMer, one of the common 

 mountain species of the Alps and Pyrenees, dotted the rocks of 

 the valley with its white rosettes of spatulate coriaceous leaves, 

 Sedums were numerous : among others, S. acre, Telephium, and 

 (though not in flower) altissimum, like a large white-flowered S. 

 reflexum. Another plant of the same Order, Umbilicus pendu- 

 linus, as common on moist rocks and walls in the south of Eu- 

 rope as in our western counties, was also present. Bryonia dioica 

 was visible, and Paronychia serpyllifolia, a mountain species, takes 

 the place of P. argentea. Of Umbellifers, besides those already 

 mentioned, I saw Heracleum Sphondylium (unless it was the very 

 similar H. pyrenaicum) , Buplcurum rotundifolium, and, I believe, 

 Orlaya platycarpa. The Cornel-tree {Cornus samjuinea) was as 

 common here as elsewhere. Of the Order Caprifoliacece, there 

 were the common Elders {Sambucus nigra and Ebulus), and two 

 Honeysuckles, Lonicera implexa of the plains, and Xylostewn of 

 the mountains. There were the blue Asperula arvefisis and several 

 Galia ; two Valerianecs, V. officinalis and Centranthus angustifo- 

 lius ; Dipsacus sylvestris, and a Knautia, apparently a variety of 

 K. arvefisis. 



Compositce were of course less numerous than in the plains or 

 at a later period of the year. There were, however, several. 

 Achillea odorata, a plant of southern Europe, like a dwarf A. 

 Millefolium, with a sweet smell of camomile, was one. With this 

 was a Santolina, probably S. Chamcecyparissias, an Artemisia, 

 probably campeshis, and the universal Leucanthemum vulgare. Of 

 Thistles on this occasion I have no note. The Centauries were 

 C. Cyanus, C. Scabiosa, and another species, not uncommon on 

 the less elevated mountains of the South, C.pectinata, deriving its 

 name from the comb-like structure of its involucral appendages.
