BOTANY.
Introductory Remarks.
BY WM. MATHEWS, M.A.
In attempting to describe the more interesting features of the indigenous Flora of the neighbourhood of Birmingham, it is necessary to define the limits of the district intended to be included. A circle of 20 miles radius, with the Town Hall as its centre, has been found convenient as an approximate boundary. This will enclose portions of the three counties of Warwick, Worcester, and Stafford, which meet at a point on the south-western edge of the Borough, and a small part of the County of Salop. The latter, with the exception shortly to be mentioned, will be excluded from consideration. On the other hand, the radius must be extended about two miles on the south-east to take in the town of Stratford-on-Avon, and about the same distance on the west to take in the woodlands west of the Severn from Shrawley Wood to Wyre Forest near Bewdley. A part of the Forest is in Salop, and to this extent only is the latter county admitted. The district thus defined contains an area of about 12,500 square miles. It includes the towns of Birmingham, Sutton Coldfield, Tamworth, Nuneaton, Coventry, Leamington, Warwick, Stratford, and Alcester, in the County of Warwick; of Bromsgrove, Droitwich, Stourport, Bewdley, Kidderminster, Stourbridge, Halesowen, and Dudley, in Worcester; of Wolverhampton, Walsall, Penkridge, Cannock, Rugeley, and Lichfield, in Stafford.
