Several plants are only indirectly connected with the character of 

 the soil, being parasitic on other plants. They are, notwithstanding, 

 more or less, dependent on the peculiarity of the soil, as the plants on 

 which they establish themselves are necessarily affected by it. The 

 principal flowering parasites of Suffolk are Viscum album ; and various 

 species of Cuscuta and Orobanche. 



A large portion of our County Flora is comprised in the plants of 

 the heavy and mixed soils, either as laid down in grass or cultivated. 

 On these the effect of man's hand is specially manifest ; and the species 

 occurring are in part aboriginal, and in part introduced, either inten- 

 tionally or accidentally. Some heterogeneous examples are here given : 

 Myosurus minimus ; Aquilegia vulgaris ; Delphinium Ajacis ; Arabis 

 perfoliata ; Silene noctiflora ; Malva moschatu ; Geranium pyrenaicum 

 androtundifolium-, Linum perenne; Radiola millegrana, (in damp spots) ; 

 Medicago maculatu ; Trifolium ochroleucum ; Lathyrus Aphaca and 

 Nissolia ; Chrysosplenium alternifolium and oppositifolium, (on shady 

 banks of streams) ; Bupleurumrotundifolium ; Anthemis arvensis ; Senecio 

 jqualidus ; Centaurea Calcitrapa and solstitialis ; Crepis taraxacifolia ; 

 Pyrola rotundifolia ; Verbascum Lychnitis and virgatum ; Antirrhinum 

 Orontium ; Mentha silvestris ; Primula elatior ; Centunculus minimus ; 

 Polygonum Bistorta ; Fritillaria Meleagris ; Gagea lutea ; Colchicum 

 autumnale ; Equisetum maximum. 



Certain plants require not alone a.^pecial soil for their full develop- 

 ment ; they also seek the shelter of a wood. Thus our woodlands, be- 

 side the taller growth of Quercus, Fagus, Castanea, Carpinus, Betula 

 and their undergrowth, Euonymus, Rhamnus, Crattegus, Cornus, Acer, 

 Primus and Corylus have a flowery carpeting of herbaceous plants : 

 such as Anemone nemorosa; Ranunculus auricomus; Viola silvatica; 

 Hypericum perforatum and hirsutum ; Oxalis Acetosella ; Lathyrus sil- 

 vestris ; Fragaria vesca ; Geum urbanum and rivale ; Circcea lutetiana ; 

 Sanicula europcea ; Gnaphalium silvaticum ; Hieracium vulgatum and 

 umbellatum ; Vinca minor ; Myosotis silvatica ; Melampyrum cristatum 

 and pratense; Veronica Chamccdrys and montana; Stachys Betonlca; 

 Teucrium Scorodonia; Primula vulgaris ; Lysimachia nemorum; Mercurialis 

 perennis ; Orchis mascula ; Habenaria chlorantlia ; Listera ovata ; Neottia 

 Nidus-avis ; Epipactis latifolia ; Narcissus Pseudo-narcissus ; Convallaria 

 majalis ; Ruscus aculeatus ; Endymion nutans ; Luzula Forsteri and pilosa ;
