IV.— THE WESTERN DIVISION This division, designated by '^' in the tables of species, is bounded on the east by a line drawn from Santon Downham on the Little Ouse river northwards through SwafFham, and reaching the sea in the north near Burnham Deepdale, and includes all westward of this line to the county boundary. It contains in its eastern portion a large tract of high, sandy, and calcareous land, which reaches the greatest elevation of the whole county near Massing- ham. The marshes on its northern edge are mostly, if not all, brackish or salt, but from Brandon northwards there is a very extensive range of fenland. On the arid land west and north-west of Swaffham there is a continuation of the pecu- liar flora noticed in the South-Central Division, with many additional species among them : Viola hirta. Astragalus danicus, Caucalis daucoides, Herniaria glabra, Thesium humifusum. Orchis ustulata, Herminium Monorchis, Festuca uniglumis. This dry country shades off towards Lynn into swampy heaths and fens very rich in plants. Here the late Mr. Bray was the first to find Microcala filiformis, a species apparently quite out of its latitude, so far as Great Britain is concerned, although its distribution extends northward to Denmark. This district has been one of the longest known and most prolific habitats in the county for Lastrea cristata and L. uliginosa. Dr. Lowe has recorded Asplenium acutum from Roydon. Narthecium Ossifragum and Schollera Occycoccus also grow here. Thalictrum majus has been recorded for more than one station at the Burnhams, and is placed by Mr. Munford in his ' ff^' division, although, as defined by Mr. Kirby Trimmer, both stations would be really in the ^NC' division, but having visited the vicinity of the 'Gallow' or Gallows Hill this year (1900), the writer saw there nothing but T. collinum, and but very little of that species. 53
