second visit Mr. P. D. Williams brought some fresh specimens 
which the writer considered showed evidence of Tetralix as a parent. 
As it was desirable to see the living plant (a solitary bush) in its 
native habitat, Mr. Williams kindly motored Professor Graeber, 
Professor Schroeter and the writer first to his beautiful grounds, 
where he has a plant in cultivation, next to the plant in situ. A 
careful examination of the plant and its surroundings induced all 
three botanists to agree that the hybrid must be E. Tetralix x 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, suggested 
the presence of vagans, both species being in the immediate vicinity. 
Planta suffruticosa, ramosissima, 40 cm. alta. Floribus axil- 
laribus vel interdum subterminalibus, in tense roseus, urceolatis, 
staminobus vagante similibus, sed inclusis, stylis prolongates. 
Foliis linearibus, marginibus recurvatis, prope hispido-ciliatis ; 
ovariis hirsutis. I have named it (Gard. Chron., Dec. 2nd, 1911) 
x E. Williamsii after its discoverer. It has been independently 
described in the Kew Bulletin, 1911, p. 378. 
1696. E. Mackayi Hook. was in good flower at its classic 
locality, Craigga More, Co. Galway. The glabrous fruit appears to 
be a constant character. 
1697. E.cilaris L. Abundant on a damp heath near Perran- 
well. 
E. ciliaris x Tetralixs=E. Watsoni, Benth. An obvious 
intermediate, almost certainly this hybrid, growing with both parents 
in the same locality. 
1704. Boretta cuntabrica O. Kuntze (—Dabeocia polifolia). The 
profusion of this beautiful species at Roundstone greatly rejoiced 
the foreign visitors, as did the extensive sheets of Erica vagans in 
Cornwall. 
1707. Pyrola rotundifolia L. var. arenaria Koch was still in 
flower in small quantity at Southport, but building operations and 
the golf have sadly restricted its area and indeed threaten its 
existence. 
1713. Limonium vulgare Miller in various forms and as var. 
pyramidale Druce grew at Havant, Hants, S. 11: the hybrid with 
L. humile (L. Neumanni C. E. Salmon) also occurred. 
1716. Limonium reticulatum Miller, L. humile Miller and L. 
binervosum C. E. Salmon were all found in good condition at 
Blakeney 28, the latter in two modifications. 
1714. L. humile Miller was also seen at North Bull 21, Ireland, 
and at Havant, Hants, S. 11: 
1722. Statice maritima Mill. (=Armeria maritima) at North 
Bull, Co. Dublin. The common plant on Ben Lawers was an alpine 
form of S. linearifolia Laterr., not as has been suggested (Williams 
Alp. Fl. Brit.) S. alpina Poiret. S.linearifolia was also the common 
coast plant at Blakeney, Norfolk, W. 28, Southport 59, Dublin, 
Roundstone, Galway, and the Lizard, Cornwall 1. [This latter 
plant differs in the spaces between the ribs of the fruit-calyx, being 
destitute of hairs, which are confined to the ribs only. In true 
maritima the hairs occur also between the ribs, a character which 
was used by their monographer Boissier to divide the Thrifts into 
Pleurostichous and Heterostichous groups. In Britain, however,
