INTEODUCTION. 



It is probably owing to its actual, but modified, insularity that 

 the following eminently mainland species, natives of Hants, are 

 wanting to the Isle of Wight, although abounding in localities 

 apparently well suited to their production : — 



1. Couvallaria majalis 



2. muUiflora 



3. Polygonatum 



4. Fritilkria Meleagris 



5. Paris quadiifolia 



6. Acorus Calamus 



7. Actinocarpus Damasonium 



8. Campanula patula 



9. Kapunculus 



10. Phyteuma orbiculare 



11. Melampyvum ciistatum 



12. Daphne Mezereum 



13. Viscum album 



14. Hordeum sylvaticum 



15. Tillaea muscosa 



16. Sagittaria sagittifulia 



17. Hydrocharis Moisus-ranae 



18. Cephalanthera ensifulia 



19. Dipsacus pilosus 



It is not so easy to assign a cause for the apparently total 

 absence from the Vectic Flora of the subjoined plants, all of 

 which are natives of the county, where, as in other parts of the 

 kingdom, they seem either to evince no particular partiality for 

 an inland over a maritime locality, or, as in the case of some of 

 those now enumerated, decidedly abound most on or towards 

 the sea-coast. These last are, for distinction, printed in Italics. 



Drosera longifolia 



anglica 



Matricaria Chamomilla 

 Teesdalia nudicaulis 

 Diplotaxis tenuifolia 

 Isnardia palustris 

 Crambe marilima 

 Petasiles vulgaris 

 Centaurea Calcitrapa 



Cicendia filiformis 

 Sartsia viscosa 

 Euphorhia paralia 

 Lycopodium inundatum 

 Spiranthes jestivalis 

 Hypericum dubium 

 Polypogon monspeliensis 

 Litorella lacustris 

 Cardamine amara 



To these should perhaps be added Helleborus viridis, Taxus 

 baccata and Lysimachia Nummularia, all of which are confined 

 in this island, to single and very suspicious stations ; those for 

 the first and third have indeed been since destroyed. 



It may be here observed, that the limitation of any plant to 

 a single locality, and its restriction in that locality to even a 

 single specimen, is, per se, no sufficient reason for its rejection
