170 On the Species of the Genus Primula in Essex. To this I have but little to add, except that the Primrose certainly grows in a great many localities other than those specially mentioned. I have met with it in most parts of the county, except at Walden and Bardfield, and the district lying between those places. I have never seen it more abundant than on the railway-bank and in hedgerows between Sudbury and Chappell, and in the district to the N.W. of Chelmsford, round Chignal, Mashbury, and the Easters, as far as Pleshey. North of that place and about Dunmow it grows more sparingly, but is still not rareā€”in fact it seems to be a common plant throughout the county, except in the district to the S. and S.E. of Walden, extending, perhaps, as far as Great Bardfield, in which parish it does not grow, as I know from several sources. Henry Doubleday says so;28 I have never met with it there, and various friends and relatives residing in the parish have informed me that it does not exist there. However, I know that it grows in the parishes of Great and Little Saling, Stebbing, Shalford, and Lindsell, which adjoin Great Bardfield on the S., E., and S.E. It will be observed that the tract of land from which the Primrose is absent is that district in which, of all others, P. elatior abounds, and this is both a strange and interesting fact. The valley of the brook Slade, and the Cam seem to mark the western boundary of the Oxlip in the Walden district. On the western side of this the Primrose grows pretty commonly, and is well distributed; thus I have met with it at Clavering, Langley Lawn Wood, Great and Little Chishall, Heydon, Chrishall, Elmdon, Wenden Lofts, near Elmdon Lea and Littlebury Green, Strethall, Great and Little Chesterford, and in the Slade Valley. In the valley of this small brook, which, as I have before stated, forms the western boundary of the P. elatior area, a curious mixture of Primulas is to be met with. If we go up it for about a mile from Saffron Walden we shall see two woods opposite one another on either slope. Entering that on the right hand, (Grim's Ditch Wood), we shall find, just on the edge, plenty of Primroses, a few Cowslips, with some Hybrid Oxlips, and an 28 'Phytologist,' vol. i., p. 204,
