tribution amount to 928, a high number, when it is remembered 

 that the maritime Flora hardly exceeds 30. 



With the exception of Rcemeria hybrida, marked as probably 

 introduced, Cambridgeshire has no British plant peculiar to itself. 

 It shares its most characteristic species with Suffolk and Norfolk 

 and others of the eastern counties. Such are Apera interrupta, 

 Medicago sylvestris, M. falcata (all three treated as natives), 

 Statice caspia, Primula elatior, Silene Otites, Carum Bulbocasta- 

 nuni, Seseli Libanotis, Barkhausia foetida, Phleum Boehmeri, Me- 

 dicago ininhna, Galium anglicum ; and the well-known rarities 

 of the Fens, many of them already lost. Cineraria palustris, 

 Sonchus palustris, Sturmia Loeselii, Senecio paludosus, Viola stag- 

 nina, etc., nearly all of which belong to the " Germanic ^' or 

 eastern "type" of Watson. It is indeed the comparative preva- 

 lence of this group which forms a principal feature of its Flora, 

 for out of the 127 species placed by Watson in his Germanic 

 type more than 80 occur in Cambridgeshire. 



At the same time it is remarkable that several of the most 

 local " Germanic " plants are wanting, e.g. Holosteum umbella- 

 tum, Veronica verna, Artemisia campestris, Verbascum floccosum, 

 apparently restricted to the adjacent counties of Suffolk and Nor- 

 folk ; and others with a wider range, Turritis glabra, Veronica 

 Triphyllos, Cynoglossum sylvaticum, Carex bonninghausiana. We 

 miss also Hordeum sylvaticum, Daphne Mezereon, Phyteuma or- 

 biculare, and some of our rarest Orchids^ which do not reach so 

 far north. 



The southern or " English " type plants constitute a large pro- 

 portion, and include, like the former group, many rare and local 

 species, such as Hypochoeris maculata, Vicia gracilis, Chenopo- 

 dium hybridum, Veronica spicata, and many others, too nume- 

 rous to be quoted at length. 



The northern or " Scottish " and " intermediate " types have 

 few representatives in Cambridgeshire : Thalictrum saxatile, 

 Drosera anglica, Sanguisorba officinalis, Potentilla verna, Par- 

 nassia palustris, Antennaria dioica, Campanula latifolia, Galeop- 

 sis versicolor, Pinguicula vulgaris, Potamogeton prcelongus, Carex 

 dioica, and C. filiformis, nearly all of Avhich range further south 

 in the damper climate and more hilly country of the west of 

 England. 



Erodium moschatum, an escape only, is the single species of the 

 " Atlantic " or south-western group which occurs in the list.
