Order 7. ERICACEAE.
l. ERICA, L.
1. E. tetralix, L. Native. British type. Area C, N, D. Range 1-3.
Frequent on damp heaths, ascending to 600 yards on Cheviot, 700 yards on Kilhope.
2. E. cinerea, L. Native. British type. Area C, N, D. Range 1, 2.
Frequent on heaths, but preferring drier ones than the preceding, and consequently not so common amongst the upland moors or ascending so high. Rare for instance in the upper part of Teesdale, but seen on the basalt at 500 yards at the Caldron Snout and as high in the Cheviot tract. There are fine specimens of E. vagans in Robertson's collection in the Newcastle Museum, labelled "Near Corbridge, July, 1844, Mr. T. Johnson," but doubtless some mistake has occurred.
2. CALLUNA, Salish.
1. C. vulgaris, Salisb. Native. British type. Area C, N, D. Range 1-3.
Everywhere very common on heaths, ascending to all the high peaks, Cheviot, 850 yards, Kilhope Law, &c.
3. ANDROMEDA. L.
1. A. polifolia, L. Native. Intermediate type. Area N. Range 1.
Rare in peat bogs. In the Wansbeck tract at Darden Lough
