available, and I have got a small list of my own from district 

 X, with these exceptions nearly everything is yet to be done. 



I will myself willingly undertake the general editing and 

 responsibility, the examination of metropolitan and other 

 herbaria, the determination of all critical forms and the 

 physiological notes. I have procured, for the use of any friends 

 who will assist me, interleaved copies of the 7th edition of the 

 London Catalogue of British Plants — one for each district, 

 though more can easily be obtained if taken up — and the 

 species here named, can nearly all be determined from Dr. 

 Hooker's Student's Flora. I should wish each list confined to 

 one district ; several localities to be given for uncommon species, 

 in each district; a note as to the frequency, i.e. number of 

 localities, and abuaadance, i.e. number of plants of each species ; 

 of the nature of its habitat, whether (to use Mr Watson's 

 terms) it is 'pratal,' i.e. growing in rich, damp grass-lands or 

 meadows, or 'pascual,' in pastures and on grassy commons, less 

 luxuriant than the preceding, or ' ericetal,' on moors and heaths, 

 or, ^uliginal,' in swamps or boggy ground, such as that in 

 which Drosera grows, or 'lacustral,' plants either continually 

 immersed in, or floating on, water, as Lemna and Nymphsea, or 

 'paludal,' i.e. in marshy ground with their roots in water all 

 the year round, or nearly so, as Alisma Plantago, or ' inundatal,' 

 i.e. in ground often dry in summer but submerged in the rainy 

 season, as is the case with Ranunculus hirsutus, or 'viatical,' 

 by roadsides or on rubbish, as Lamium purpureum and Urtica, 

 or ' agrestal,' on cultivated ground, as Papaver or Scandix, 

 or ' glareal,' in dry, exposed situations chiefly on gravel or sand, 

 or 'rupestral,' on walls and rocks, as Saxifraga tridactylites, 

 or 'septal,' on hedge-banks or in hedge-rows, as Stellaria 

 holostea, or ' sylvestral,' in woods and shady places, as Paris 

 quadrifolia and Convallaria majalis, or ' littoral,' on the 

 sea-shore, as Convolvulus Soldanella, Armeria, or Eryngium 

 maritimum. 



One word will also sufiice to indicate the surface soil. Notes 

 of visiting insects or physiology should be made in a separate 

 note-book.
