214 APPENDIX. 



Statice emarginata, just beginning to flower, but unfor- 

 tunately growing beyond my reach ; I could, however, 

 gather a few specimens, by climbing twenty feet, to the 

 great alarm of a sentry, who ran, supposing I was going to 

 take the fortress by storm, and was only satisfied as to my 

 intentions by seeing my pass. Further on I only found a 

 narrow path at the foot of the sandy bank, against which 

 the sea was dashing much more furiously than on the side 

 next the gulf. This part of Gibraltar being completely 

 isolated from the other by natural escarpments, is not 

 included in the line of fortifications ; and it would be 

 sufficient to roll stones from the top of the mountain to 

 drive away any assailants. There is here a very small 

 hamlet, inhabited by fishermen; and a sentry is placed 

 to prevent any one from disembarking. This side is cer- 

 tainly the most interesting on a botanical account, and I 

 regretted being able to make only one excursion, which 

 the difficulties of the ground rendered very insufficient. 

 On the sandy declivities I found particularly the Ononis 

 Gibraltarica, a new species, which was very abundant 

 there, the yellow flowers of which perfumed the air, the 

 Brassica papularia, Linaria longipedunculata and multi- 

 punctata, Caucalis maritima, and several kinds of Daucus. 

 Vegetation on the whole rock is very interesting ; but the 

 greatest number of plants grow at so great a height, on 

 .narrow niches, that it is dangerous to attempt getting them. 

 Amongst others I could only procure a single specimen of 

 the Silene Gibraltarica, large tufts of which I saw above 

 my head; I found again Calendula marginata, Stachys 

 circinata, Helichrysum rupestre, with the Ephedra altis- 

 sima, Achyranthes argentea, Succowa balearica, and the 

 elegant Iberis Gibraltarica, whose flowers were already 

 over. By the richness of the harvest, which I collected 

 in a few minutes, I could judge of the interest which 

 exploring Gibraltar could afford, and particularly on this
