A FLORA OF GIISRALTAR AND THE NEIGHBOURHOOD xiii 



pi'ovince of Ciidiz — in Anales Soc. Hist. Nat. Espan. His work 

 runs interruptedly through vols. xv. — xxvii. (1898), and was com- 

 pleted in 1903 by an appendix published in the Mem. Soc. Esp. 

 Hist. Nat., vol. ii. Ho does not include many of the previous 

 records, but the later ones of Eeverchon, Winkler, Dautez, and 

 other collectors, are all noted. The Florida contains useful notes 

 on some of the species, though their utility would have been 

 enhanced had more attention been given to the difi'erentiation of 

 allied species and varieties than to a mere statement of their range 

 of variation, which is confusing rather than elucidatory. 



Gibraltar being geographicallly considered as part of Spain, 

 no special effort has been made to segregate its records, conse- 

 quently several for the neighbouring country have been credited 

 to the Eock itself, and sometimes the reverse mistake has been 

 made. This is doubtless due to the comprehensive use of the 

 name "Gibraltar" by most collectors, and the ambiguity of the 

 name " Neutral Ground," though not actually used by Perez 

 Lara, also has led to confusion. 



Perez Lara's work was a great advance on Kelaart's, and 

 surpasses in utility and number of local records that of Debeaux, 

 though the latter was specially devoted to the flora of Gibraltar 

 and its neighbourhood. The total records for the whole province 

 are 1905 species, and after making due allowance for excluded 

 species, doubtful records, naturalized aliens, and those reduced to 

 varieties, there are the following records for our region : — 



For the whole region . . 951 

 For Gibraltar only . . 462 



These totals are doubtless larger than they should be, because 

 I have included all species known for our region which Perez 

 Lara specifies as common in the whole province, without giving 

 any detailed stations. Some of these are certainly rare with us, 

 a few are not recorded, and quite a number are not known for the 

 Eock ; these last I have, of course, not included in the totals. It 

 is highly probable that no station within our limits was known to 

 Perez Lara for many of the others, but I have been unable to 

 discriminate, so had no alternative but to include all that I knew 

 to exist with us. 



A Synopsis de la Flore de Gibraltar was published by 

 0. Debeaux in 1888 in Actes Soc. Lin. Bordeaux, vol. xlvii. The 

 author was but slightly acquainted with the region, and appears 

 to have done little or no collecting there himself, relying mainly on 

 notes and specimens submitted to him by Dautez : consequently 

 he gives quite a false impression of the relative frequency of the 

 species, as well as sometimes wrongly assuming a variety only to 

 exist, whereas the type is far the commoner. His prefatory 

 remarks also lose much of their value from the obscurity of his 

 topography ; tluis, he confuses St. George's Hall, on tlie northern 

 precipice, with St. George's Tower, near the southern end, better 

 known as O'Hara's Tower but now demolished. I have not, 

 therefore, availed myself of the special localities given in that
