182 VEGETATION OF THE 



nus, and another species, with many kinds of Centau- 

 rea, Carduus, &c. 



For convenience sake we shall suppose the botanist 

 to have regained the high-road to St. Roque. On the 

 left of the Queen of Spain's Chair the small village 

 of Campo is situated, near the upper end of the race- 

 course ; the road passes through, thus making it a kind 

 of halfway -house to frequenters of St. Roque. It is 

 considered a very salubrious place, and is conse- 

 quently made the summer residence of invalids from 

 Gibraltar; and a few merchants take apartments 

 there for their families. The air about here is purer, 

 but being much exposed to all winds, which fre- 

 quently blow very boisterously across the plain, espe- 

 cially in the winter months, there is no inducement 

 for making the village their permanent residence. 

 A little way beyond the outskirts of Campo, towards 

 the bay-side, is the newly-discovered Roman ruin 

 alluded to in a former part of this book. Near this 

 locality, the Centaurea polyacantha grows in great 

 abundance ; on the right of the high-road there are 

 some extensive fields, where the beautiful Hedysarum 

 coronarium is seen in great profusion ; this plant is 

 found nearly all the way to St. Roque, forming large 

 crimson masses among the green of the barley and 

 oats, and makes excellent fodder for cattle. On the 

 road-side there is a variety of plants; the principal 

 kinds are Helminthia echioides, Passerina canescens, 

 Mentha Pulegium, var. tomentella, Salvia rotundi- 

 folia, S. boetica, Cerinthe major, Scorpiurus sub-
