clxXXviii FLORA OF BERKSHIRE 



edition of the same work. When Linnaeus gives a reference in his 

 Genera Plantariim to a previous writer or a synonym, I have usually 

 quoted it. The references to the Institutes of Tournefort are to the 

 plates, not to the pages. 



Beneath the name of the Ge)ius comes the Specific name printed in 

 Clarendon type, followed by the name of its author and the place, and 

 usually the date, of publication. The original spelling is retained as 

 far as possible ; in a few cases this has caused an apparent want of 

 uniformity, e.g. in the genus Potamogeton, which Linnaeus treated as 

 neuter, and therefore wrote P. pusillum, &c., while more correctly 

 subsequent authors have considered it to be masculine, and we there- 

 fore find P. acutifoUus, Link, &c. In the genera Capnoides, Helleboroicles, 

 and Juncoides too, there is a diversity of practice. Kuntze and others 

 have written Juncoides sijlvaticum and Helleboroides hyemale, while we liave 

 Capnoides lutea of Gaertner. 



The names of species that are evidently not native to the county 

 are printed in small roman capitals. 



Then follows the Popular name in italics ; mere translations of the 

 scientific name are purposely avoided. 



Below these are placed various synomjms, printed in italics. Such 

 are given when the name in Syme's English Botany, Babington's Manual 

 of British Botany, Hooker's Studenfs Flora, or The Index Kewensis differs 

 from the one I have adopted, in order to make the work more useful 

 to those readers whose botanical library is limited. A few pre- 

 Linnean names are cited for the purpose of showing the genesis of the 

 name employed here. 



Eeferences are given to the second edition of Topiographical Botany, to 

 the third edition of English Botany, with the page and plate, to Nyman's 

 Conspectus of European Plants, and to the author's Flora of Oxfordshire ; the 

 plates of Baxter's Phaenogamous Botany are also cited whenever they were 

 probably drawn fi'om local plants. 



The plants enumerated have not been described in detail since the 

 many descriptive British Floras render this unnecessary, but should 

 the plant exhibit any local variation, attention will be directed to it. 

 The plates in Syme's British Botany, which may be found on the 

 reference shelves of the Bodleian Library, are quoted throughout, and 

 the author takes the present opportunity to point out the very excellent 

 descriptions given in the text of that work, which were drawn up by 

 Dr. Bosvvell Syme. (The so-called popular portion written by Mrs. 

 Lankester is not included in this commendation.) 



The next paragraph contains, first, the grade of citizenship of the 

 plant in Berkshire, that is whether it is a Native, apparently an 

 aboriginal British species, as, for example, BelHs; or Denizen, at present 

 maintaining its habitats, as if a native, without the aid of man, yet
