 A HISTORY OF HEREFORDSHIRE (^Euphorbia Lathyris) seems to be a true native in a single rocky limestone wood ; the yellow star of Bethlehem {Gagea luted) at a single spot in a shady meadow bank ; while the monk's-hood {^Aconitum Napellus occupies the bushy banks of a single stream. The rare loose-strife (Lythrum hyssopifolla) was once found in gravel brought from the Wye.

This tract extends from Dormington and Mordiford on the north to the boundary of the county of Gloucester on the east and south. The main roads running through Tarrington, Stoke Edith, Dormington, and Mordiford, and thence in a south-east direction to the Lea, and coinciding with tolerable exactness with the Imes of the geological strata, have been made use of as boundaries. The geological characters of this district are both remarkable and well known ; their study gave rise to the title of the ' Woolhope Field Naturalists' Club,' which has done so much and such excellent work both for the geology and natural history of the county. There is a large area of woodland in this district, yet it is to some extent disappointing in the numbers of rare species of flowering plants found within its limits. By far the most interesting botanical feature yet brought to light here is the caraway [Carum Carvi) which occupies an area of old pasture land m the Woolhope neighbourhood extending some two square miles, and is apparently a native wild plant. Many plants showing a preference for dry limestone hills abound in the hills of this section of the county such as the mealy guelder-rose [Viburnum Lantana), the liquorice vetch [Astragalus glyciphylhs), and the slender bird's-foot trefoil [Lotus tenuis). The Juniper [Juniperus communis) occurs on Marde Ridge Hill, and the beautiful spring cinquefoil [Potentilla vema) is abundant throughout the district. 44
