Nitella opaca, Agardh Having for its eastern boundary the Lower Tamar District, for its southern a much broken and for the most part precipitous coast line ranging from Downderry to Pentewan, for its western the high road from Pentewan through St. Austell, Ruddlemoor, and Roche, to the five turnings a mile or so beyond the latter village, and for its northern the road from the five turnings mentioned through St. Ingunger, Lanhydrock, Bodmin, Cardinham Downs and Bolventor, to Poldew, this division repeats most of the physical features so markedly noticeable in the two districts already described. It is essentially a district of woods and romantic valleys, and an ideal hunting-ground for the botanist. Along their upper parts the valleys through which the Fowey, Looe and Seaton rivers flow offer nothing of startling importance, but as the estuaries are reached a considerable variety of plants will be found, not a few of them being among the rarest in the British flora. Save the north-east, which includes a goodly portion of the Bodmin Moors and the Caradon Hills, and a small corner of Hensbarrow Hill, in the west, this piece of Cornwall rarely rises above 600 feet. On the whole its flora has much in common with that of the Channel Islands and north France. From the eastern limits of this district to about 2 miles west of the common estuary of the two Looe rivers Lower Devonian rocks occur. Upper Silurian become visible a little to the west of the Hore Stone, and join the Lower Silurian in an almost straight line to about midway between Lostwithiel and Bodmin. A small exposure of the same rocks is again met skirting St. Austell Bay, terminating with Black Head. West of the Upper Silurian the Hensbarrow Granite Boss rises through an almost perfect belt of Lower Silurian to an elevation of 1,026 feet. At Clicker Tor, between Menheniot and the coast, there is a limited outcrop of magnesian rocks analogous in character with those of the Lizard District Erica vagans, a glorious feature of the Goonhilly Downs, has been reported from the Menheniot 59
