INTRODUCTION. xiii 



synonyms to every plant, but only to a few, where 

 I thought it would be expected by the local botanist, 

 who cannot have reference to new and expensive 

 works ; and who will, I trust, also find his inquiries 

 facilitated by the observations, which were chiefly 

 addressed to those friends who honoured me with 

 their presence when my humble attempts were made 

 to diffuse a botanical taste, in my discourses at the 

 residence of the Archdeacon of Gibraltar, the Rev. 

 Dr. Burrow, on those occasions when that zealous 

 cultivator of natural science entertained the ladies 

 and gentlemen of the rock with literary and scientific 

 subjects. 



In Part IV. I have endeavoured to give a short 

 account of the topography and vegetation of the 

 neighbourhood of Gibraltar, which may also be use- 

 ful to the botanist who may extend his inquiries 

 further into Spain. 



The Appendix contains a translation of Boissier's 

 description of the vegetation of Gibraltar, which can- 

 not be too widely circulated ; and I doubt not that it 

 will be read with great interest, as also his description 

 of new plants.
