liable to some suspicion of having been originally introduced, as 

 Helleborus foetidus ; or a Colonist, a weed of cultivated land, or about 

 houses, and seldom found except in places where the ground has been 

 adapted for its production by the operation of man, as Papaver Rhoeas : 

 Alien, now^ more or less established, but either presumed or certainly 

 known to have been originally introduced from other countries, as 

 Mimulus ; or a Casxial, which may be defined as a plant, either of 

 exotic origin or indigenous to some part of Britain, but which is not 

 at present permanently localized in Berkshire situations, as Erysimum 

 repandum and TJdasplperfoliatum. Secondh'^, the habitat of the plant : I use 

 the term Pratal for plants of meadow or rich and damp grass lands, 

 as Geranium pratense ; Pascual for plants of pasture and grassy commons 

 where the herbage is less luxuriant than in the meadow lands, as 

 Prunella and Trifolimn repens ; Ericetal for plants of heaths, as Calluna and 

 Scir2nis caespitosus ; Uliginal for plants of swamps or boggy ground, as 

 Brosera ; Lacustral for plants usually immersed in water or tioating on 

 its surface, as Potamogeton ; Paludal for plants of marshy ground, the 

 roots of which are in water or wet ground most part of the year, or 

 constantly, as Typha and Parnassia ; Inundatal for plants on places 

 liable to be inundated in wet weather, but often dry in summer, as 

 Pulicaria vulgaris ; Viatical for plants of roadsides, rubbish-heaps, and 

 frequented places, as Urtica dioica ; Agrestal for plants of cultivated 

 ground, as Veronica agrestis ; Glareal for plants of dry exposed ground, 

 chiefly on gravel, chalk, or sand, as Ornithopus and Sedum acre ; Eupestral 

 for plants of walls and rocks, as Cotyledon ; Septal for plants of liedge- 

 banks and hedgerows, as Stellaria holostea ; Sylvestral for plants of woods 

 and shaded places, as Paris. It will be obvious that some of our plants 

 may be put in two or more of these divisions. To the habitat is attached 

 more full description of its places of growth, and a statement as to its 

 frequency or rarity in the county. Thirdly, the time of flowering 

 and the duration, annual or otherwise. 



A paragraph is then devoted to giving the earliest record for the 

 plant in Berkshire with which the aiithor is acquainted, with the 

 date, the name of the recorder or finder of the plant in the county, 

 the name by which it was called, and the locality in which it grew. 

 This record may be a printed (ftiese have the preference) or a Ma-itten 

 one, published or unpublished ; it may be a dried specimen or a MS. 

 note ^. Although extreme pains have been taken to ensure that the 

 record quoted is the earliest, it is possible that subsequent research 

 may in a few instances discover some that are earlier. The compila- 



"^ The unpublished ones are always printed in italics ; when the record is 

 published the name of the work is in italics ; when the finder of a plant 

 publishes the record in a journal or when some one else publishes his record, 

 the name of the finder is given in Roman letters.
