Among the examples of the type may be instanced the following : 

 namely, Frankenia lajvis, Anemone Pulsatilla, Reseda lutea, Silene noc- 

 tiflora, Silene conica, Bupleurum tenuissimum, Pimpinella magna, Pu- 

 licaria vulgaris, Lactuca Scariola, Atriplex pedunculata, Aceras an- 

 thropophora, Ophrys aranifera, and Spartina stricta. 



"6. The Atlantic Type. — Contrary to the peculiarity of distribu- 

 tion which constitutes the Germanic type, there is in that of other 

 species a marked tendency towards the western and south-western 

 coasts or countries. Some few species are absolutely restricted to the 

 single province of the Peninsula. Others occur also in one or more 

 of the adjacent provinces. And others, again, run far up the western 

 coasts in a northerly direction, often plentifully there, and yet occur 

 very rarely, or not at all, towards the eastern coasts of the island. 

 These species, although thus dissimilar in respect of their area and 

 census, correspond in the one circumstance of having some decided 

 tendency to the western or Atlantic side of the island, in contradis- 

 tinction to the eastern or Germanic side. Although there may exist 

 other reasons for specially denominating some of these the ' Atlantic 

 species,' the name of the type will be here understood as having re- 

 ference only to their distribution within Britain itself, and by itself 

 About the same number of species are likely to be referred to this 

 type, as to the Germanic ; its arithmetical value being somewhere be- 

 tween a fifteenth and a twentieth part of the Flora of Britain. As 

 examples, we have Siuapis monensis, Matthiola sinuata, Raphanus 

 maritimus, Sedum anglicum. Cotyledon Umbilicus, Bartsia viscosa, 

 Pinguicula lusitanica. Euphorbia Peplis, Euphorbia Portlandica, 

 Scirpus Savii, — which occur in several counties ; also Sibthorpia eu- 

 ropaea, Erica vagans. Erica ciliaris, Physospermum cornubiense, Po- 

 lycarpon tetraphyllum, Adiantum Capillus- Veneris, Cynodon Dacty- 

 lon, and others which occur in very few or only single counties. On 

 pages 9 and 12, Cynodon Dactylon is inadvertently said to be found 

 only in Cornwall ; that name having been overlooked in Dr. Salter's 

 list of plants near Poole, in Dorset : a consequence of its alphabeti- 

 cal series of names, which renders comparisons with scientifically ar- 

 ranged lists so exceedingly troublesome. 



" 7. A Local or doubtful Type. — Interspersed about the island, there 

 are some species whose distribution is restricted to single or few 

 counties. Such species can seldom show that decided tendency to 

 the east or the w^est, to the south or the north, to the mountains or 

 otherwise, which would fully warrant their assignment to any one of 

 the six preceding types of distribution. In those instances where the
