THE PLAN OF THE FLORA. 



THE names and order of the species mentioned in the 

 Flora are those of the London Catalogue, ninth 

 edition, Part I. For any given plant the first entry 

 is that of the species number in the London Catalogue, the 

 insertion of which will obviate the necessity of giving other 

 references for synonymy, &c. Then follow the generic 

 and specific names, together with the acknowledged 

 abbreviation of the authority for the specific name. When 

 the authority abbreviation is enclosed in brackets it signifies 

 that such plant is recognised as a species by that authority. 

 Alien plant names are always in italics. The number which 

 follows immediately indicates the number of vice-counties 

 (H. C. Watson's, 112 for Great Britain) in which the species 

 named has been found to occur. 



Next come the common name when such exists, and 

 in certain cases, local dialect names also are added. 



The word "native," "denizen," " colonist," or " alien," 

 succeeds and marks the rank of citizenship which the species 

 is supposed to hold (see supra on distribution). The type 

 (British, English, &c.) is then given. 



The numerals following the last allude to the districts 

 into which we have divided the East Riding, i.e. Watson's 

 vice-county, 61, S.E. Vorks. (1. North Holderness ; 2. South 

 Holderness ; 3. North Wolds ; 4. South Wolds ; 5. Derwent 

 Carrs ; 6. East Derwentland ; 7. West Derwentland ; see 

 maps). 1-7 signifies general distribution. The entry of the 

 other numerals is only for such districts as we have records 

 rom. 



The name of the month indicates the time of flowering,
