Other chalk plants are found in several parts of the County. Of 

 -these the most important are : Clematis Vitalba, (frequently on mixed 

 soil) ; Reseda lutea ; Sison Amomum, (also on other soils) ; Centranthus 

 ruber; Scabiosa Columbaria; Campanula glomerata; Chlora perfoliata ; 

 Orchis pyramidalis; Aceras anthropophora ; Ophrys aranifera; Tulipa

A considerable area is occupied by the fens and marshes cf Suffolk. 

 The fens, with the exception of those on the Upper Waveney, are con- 

 fined to the Northern portion of West Suffolk, and are contiguous to 

 the Little Ouse, the Upper Ouse, and the Lark. In the parishes of 

 Lackford, Mildenhall, and Lakenheath, they have been efficiently 

 drained. The principal marshes are in East Suffolk, and near to the 

 Lower Waveney, the Aide, and the Deben. To a great extent these 

 also have been drained. There are also various lakes and broads in the 

 County, the former principally in the North-West, and the latter 

 chiefly in the North division. There is consequently a large number of 

 aquatic and bog plants, of which the following are the most interesting : 

 Ranunculus Lingua ; Nymphcea alba ; Niiphar lutea ; Droser a intermedia \ 

 D. Anglica ; Viola palustris ; Hypericum elodes ; Lathy rus palustris ; 

 Sanguisorba qfficinalis ; Comarum palustre ; Myriophyllum altermforum^ 

 (lakes and pools) ; Ly thrum Hyssopifolia, (where water has stagnated) ; 

 Cicutavirosa; Siumlati folium; Peucedanum palustre, (fens and marshes); 

 Senecio paludosus, (extinct) ; S. palustris, (likely extinct) ; Sonchus 

 palustris, (wet marshes) ; Menyanthes trifoliata, (fens) ; Utricularia, 

 vulgaris, minor, <#c., (fen pools and marsh ditches) ; Hottonia palustris 

 Myrica Gale ; Stratiotes aloides, (marsh ditches) ; Hydrocharis Morsus- 

 ranee ; Malaxis paludosa, (fens) ; Sturmia Lceselii, (fens) ; Actinocarpus 

 Damasonium, (pools, extinct) ; Sparganium minimum, (streams) ; Acorus 

 Calamus, (river banks) ; various Potamogetones, Scirpi, Carices and 

 marsh grasses ; Lastrea Thelypteris, cristata and uliginosa, (shady bogs) ;

Several plants in the County have their habitats on old walls and 

 buildings, such as : Cheiranthus Cheiri ; Diplotaxis tenuifolia ; Cardamine 

 impatient ; Dianthus plumarius and Caryophyllus ; Holosteum umbellatum; 

 Sedum album, dasyphyllum and reflexum ; Sempervivum tectorum ; Galium
