The Southern Element in the British Flora. 513 



The species of class \ are so few and for my purpose relatively so 

 unimportant, that I have not set them out in tabular form as I have done 

 with the rest. The tables for the species composing the classes 2 and 3 

 require some explanation. They consist of 10 columns apart from the 

 lists of names. Column 1 gives the northern limit which the species reach 

 in continental Western Europe. As far as France is concerned, I have 

 generally quoted departments. Where Calvados is mentioned it may as a 

 rule be assumed that the plant also occurs in the Department Manche 

 which extends a little farther north than Calvados. Columns 2 — 4 indicate 

 the distribution in Great Britain. The names are usually the names pf the 

 counties. They had to be abbreviated in some cases, but these abbrevia- 

 tions will easily be understood. 



In column 2 the distribution is from Cornwall north through western 

 England and Scotland, in column 3 from Cornwall east to Kent, in column 4 

 from Kent north through eastern England and Scotland. Where the species 

 IS only known from one county, the name of the county is given between 

 inverted comas. In some cases a species is known from only two or three 

 counties coming under one of the three columns, in which case the counties 

 are indicated. 



Columns 5 and 6 refer to the distribution in western and eastern 

 Ireland, the mode of marking the extension being the same as in 

 columns 2—4. 



Column 7 is an attempt to characterise very approximately the ecolo- 

 gical character of the conditions under which the plants are found, not 

 so much within the British Isles, as in the more southern portions of 

 their areas. 



Column 8 contains the number of » vice-counties « given in the last 

 edition (1908) of the London Catalogue of British Plants; Column 9 those 

 of the divisions of Praeger's :^ Irish Topographical Botany* (1901). In Co- 

 lumn 10 I have added the type of » distribution* as stated in Watson's 

 Compendium of the Cybele Britannica« (1870). Throughout the lists and 

 in the following text the names of the species referred by me to the 

 Atlantic element are printed in »spaced out* type.

 Some of the Fumarias and probably Linaria supina are possibly 

 t^ue natives in at least a part of the British Isles and might, with equal 

 ^^ght, be transferred to class 3, where they would add to the Atlantic 

 element. Apart from them the whole of the species of this class extends 

 far into the Mediterranean 



region.
