" A careful examination of the plant (a solitary bush) and its 

 surroundings induced all three botanists (Graebner, Schroeter, 

 and Druce) to agree that the hybrid must be E. Tetralix 

 vagans and not cinerea x vagans, since the presence of the 

 glandular hairs must have come from the former species. 

 The longer stamens, the inflorescence, and the habit, sug- 

 gested the presence of vagans, both species being in the. 

 immediate vicinity." New Phyt., 1911, p. 316. The hybrid 

 is established at Kew Gardens.

5. Reskajeague Downs between Portreath and Gwinear, 1921, 

 R. L. Smith and W. D. Watson. Several places on railway 

 bank between Gwinear Road and Hayle, 921, Rees.

" Mr. P. D. Williams, of Lanarth, Cornwall, kindly sent me last 

 September a curious variation of the Cornish heath, which he 

 had known for ten years. The cuttings come quite true. It 

 never really flowers, but young vegetative shoots are formed 

 with tiny clustered leaves 1mm. long. The pecularity may 

 be caused by a mite or gall, but Dr. W. G. Smith, to whom 

 I sent it, has not seen anything like it. Mr. E. W. Swanton 

 has little doubt that a mite causes the abnormality in growth."

7. A single plant at Trelanvean Farm, St. Keverne, on the north- 

 west corner of a rough moor. P. D, Williams. The finder 

 took cuttings (which grew), and also layered the plant. In the 

 following year the original plant and the layers were trodden 

 into the ground by cattle and destroyed. Now growing in Mr. 

 Williams' garden at Lanarth, St. Keverne, and at Kew Gardens. 

 The new plant differs from the usual form of the species 

 in the shape and colour of its corollas, characters which are 

 not easy to make out in dried material. The corollas are 

 broadly campanulate, with a wide open mouth, and well de- 

 veloped, more or less reflexed lobes. The bending back of 

 the corolla lobes varies with the age of the flowers, but in 

 mature, though not faded, examples, it is decidedly more 

 marked than in typical Erica vagans. In colour the fresh corol- 

 las are a charming rose-pink with no tinge of purple. . . . 

 Examples of reversion to the parent plant have been noticed 

 at Kew by Dr. Hill and others." Turrill, loc. cit.
