A FLORA OP GIBRALTAR AND THE NEIGHBOURHOOD XI 



taken up by later writers on the botany of Spain, while many of 

 those of Salzmann, Broussonet, and later collectors have been 

 adopted. The justification for this is not apparent, unless it be 

 that modern writers liave included species from collectors which 

 they have seen. I hesitate on my own responsibility to accept 

 them all, especially as many of them are highly improbable, tlius 

 their whole lists are open to suspicion ; but I liave included the 

 more probable ones in the list of species to be searched for which 

 is given at the end of this preface. 



Clusius worked a great deal in Spain, but his localities are not 

 precisely defined, so there are no additional records to those on 

 the Rock. Tournefort also published no list for the surrounding 

 country. Schousboe (1798-9) first found Linaria Munbyana, 

 Salvia bullata, and Narcissus viridiflorus, while Gaudichaud, who 

 gives such an interesting list of Rock plants, did not visit the 

 country round. 



Lists of plants collected by the following exist : — 



A. MS. list of Masson's plants in the National Herbarium 

 names seventeen species for San Roque, of which Satureia Juliana 

 is unconfirmed by later authors. 



Von Martius's list contains 192 species, at least twenty-five of 

 which are improbable or wanting in confirmation. This large 

 number may be due to incorrect diagnoses, or to the somewhat 

 loose application of the older names, the synonymy of which is 

 often doubtful. Others which are confirmatory of records I had 

 excluded, as well as some of the more likely ones, are taken up in 

 the Appendix to this work. 



Schott's list, which he heads "plants collected," contains 

 names of species only known for the Rock, as well as some 

 only known for the neighbourhood, so there is some doubt as to 

 whicii they should be referred to. It contains 150 species, with 

 about the same number of doubtful records as that of Von 

 Martins, to which the same remarks apply. 



Salzmann only names five species, of which only Ononis 

 hispida, for which he may have mistaken 0. Cossoniana, is 

 unrecorded elsewhere. 



Willkomm and Boissier published lists of some of the plants 

 they saw in their travels in the works already referred to. These 

 are all taken up in the present Flora. 



Kelaart's list in Flora Calpensis contains, as already explained, 

 species which occur beyond our limits ; those which are uncon- 

 firmed for our region are shown in the Appendix to this work. 



Dasoi, who collected in 1887, submitted his plants to Gandoger 

 for determination. The result is the inclusion of many im- 

 probable names. Moreover, there is no knowledge of the extent 

 of country explored by him, so that his list has no value. It was 

 published in Bull. Soc. Bot. Fr. xxxiv. pp. 223 and 309, and some 

 account of it will be found at the end of Debeaux's Flora. 



A much more trustworthy list of Reverchon's finds, mostly 

 about Algeciras in 1887, is published by Rouy in the same 

 volume (p. 434). Fritze, Winkler, Nilsson and Hackel also found
