Narthecium ossifragum and Drosera rotundifolia formerly grew at the Lower Lickey. The former was destroyed by drainage about 1854, the latter has been recently extirpated by collectors. Ceterach officinarum, which grew in great abundance on the garden wall at the Leasows from 1850 to 1884, was destroyed soon after the latter date.
III. Stour.—Country from the foot of the Clent Hills to the east bank of the Stour, near Kidderminster. Surface strata—Waterstones, soft red Bunter, Pebble bed. This sub-district is distinguished by the steep scarps of the waterstones, the sandy soils of the soft red sandstone, and the numerous pools on the brooks which flow from the Clent Hills into the river Stour. The rarer plants are—

Camelina sativa, Silene anglica, Anthoxanthum Puelii, have been found as field casuals. Mimulus luteus is established in the brooks at Churchill. Medicago maculata, Xanthium spinosum, Polypogon monspeliensis were growing in 1875 on wool waste at Hoo Mill.
Sium latifolium, which grew in Blakedown Pools, in Purton’s time, has been long extinct in that locality. Osmunda regalis, which grew in this sub-district in 1852-3, has disappeared. Asplenium Adiantum-nigrum and Scolpendrium vulgare have been all but exterminated.
Elatine hexandra and Hydropiper, reported by the late Mr. Alexander Irvine in a “Mill Pond near Churchill station,” in 1857, have not been seen by any other botanist.
IV. East Severn.—Country from the west bank of the Stour to the east bank of the Severn near Bewdley and Stourport, including Hartlebury Common east of Severn, below the junction of the Stour at Stourport. Surface strata: Waterstones, Bunter sandstone and Pebble bed, Permian breccia, Coal measures, Old red sandstone; covered at Hartlebury Common and elsewhere with modern drift. The sand and bog plants of Hartlebury Common are the most interesting features of the flora of this sub-district. It contains—
