The Thames' of my Oxfordshire Flora, and is bounded on the north by the Ock district, on the east by the river Thames, and is separated by the watershed of the Lambourn and Kennet on the west and south from the Kennet district. Although small the Pang district has many interesting features. It is wholly situate on the cretaceous and Eocene measures, and a considerable portion is more than 300 feet above sea level. The northern part is bare and bleak, and is formed of chalk down covered by short grassy turf, and almost destitute of trees ; but the turf is thickly covered with individual plants in countless numbers, although its number of species is not large. The chalk milkwort (Polygala calcarea), the rock rose (Helianthemum Cham&cistus), the squinancy wort (Asperula cynanchica), the bastard flax (Thesium humifusum), the field ragwort (Senecio campestris [S. integri- folia] the orchids 0. ustulata and O. pyramidalis, the chickweed (Cerastium arvense), the gentians G. Amarella and G. germanica, and the scabious (Scabiosa Columbaria) being the con- spicuous features. The arable fields have already been alluded to, and one of these yielded a grass which subsequent examination and cultivation shows to be a good species, and I have called it Bromus interruptus (see my Flora of Berkshire, p. 593, and Journ. Linn. Sac. (1896) pp. 42630). It differs from any other known species of Bromus by the inner pale being split to the base, as well as by its inflorescence. I have already alluded to the flora of the wooded portion of this district under the geological formations, but one can scarcely realize their charm until they have come under observation, each coppice having something fresh to show. At Hampstead Norris there is a particularly fine growth of the spurge laurel (Daphne Laureola], Unwell Woods have a very varied flora, including the Solomon's seal. Nearer Basildon, but in woods away from the river, the hellebore (H. viridis, L., var. occidentalis) occurs in quantity ; in another bushy place near H. faetidus grows. Where the chalk becomes coated with tertiaries, as at Ashampstead Common, another flora presents itself; and in this place, which resembles rather a hilly woodland tract than what is usually meant as a Berkshire common, we find very fine beech and splendid hawthorns, the true cherry (Prunus Cerasus], as well as a variety of the cow wheat (Melampyrum pratense var. latifolium), the hound's tongue and sweetbriar.
