Rh 8. , Huds. Native. Scottish type. Area C, N, D. Range 1-3. In the Cheviot tract frequent on the lower hills about Wooler and Alwinton, but not ascending to the peaks. Scattered over the moors north of the Tyne, common in the upper part of Allendale, Weardale, and Teesdale, ascending to the Main Limestone of Highneld, 650 yards, and frequent down as low as Sinderhope and Eglestone; sometimes carried lower by the streams.

1. , L. Native. British type. Area C, N, D. Range 1, 2.

Common on swampy heaths, ascending to 600 yards on Cheviot, 550 yards at the head of the Beldon Burn (Derwent), and 500 yards in Teesdale. Probably a plant of the Upper zone, but we have not seen it there.

2. , Huds. Native. Scottish type. Area N. Range 1.

Long known as a plant of Muckle Moss (150 yards) and Prestwick Carr, but doubtless now eradicated at the latter station. Wallis reports a D. longifolia from a bog on the north side of Slaterfield, near Simonburn, which may be this.

1. , L. Native. British type. Area C, N, D. Range 1, 2.

Frequent in grassy places, ascending to 550 yards in Dunsdale and Harwood Dale. The subspecies P. depressa, Wend., is frequent on heaths; and the variety oxyptera occurs in Coquetdale near Alwinton.
