1434. Cirsium palustre Scop. var. ferox mihl. Near Silverdale 
and near Carnforth 69, on the slopes of Crossfell 800-1400 feet, often 
white flowered, Cumberland 70, on the roadside near Dunkeld, E. 
Perth 89, and Lawers, near Perth 88. 
A most strongly spinous plant with more condensed inflores- 
cence than the type. The spines are pale coloured and the 
foliage of a paler green. The continental botanists agreed that it 
was quite a distinct form from typical C. palustre and suggested that 
it should be separated as a variety from the type. It may perhaps 
prove to be the Spanish plant var. spinosissimum Willkomm, 
1638 var. K. Hieracium umbellatum L. var. dunale G. Meyer. 
Southport sand dunes 59 in great quantity and although varying in 
stature well marked by the abrupt transition from long to shorter 
leaves. 
1644. Leontodon nudicaule Banks (L. hirtum L.) var. lasiolena 
Druce, Southport 59. Atthe Lizard the common plant was the 
var. leiolena Druce. 
1646. Taraxacum spectabile Dahlst. var. maculigerum Dahlst., 
near Woodsome, York 163. 
1656. Sonchus arvensis L. var. angustifolius Meyer, Blakeney 
28. 
1657 S. oleraceus L. var. runcinaius Coss. & Germ. Galway +16. 
1666. Fasione montana L. var. litoralis Fr. Clifden, Galway 16. 
1687. Oxycoccus quadripetala Gilibert (Vaccinium Oxycoccus). 
In some quantity on Foulshaw Moss 69, passed by Professor 
Lindman as the typical plant; a smaller plant with narrower leaves 
of a slightly different outline which grew sparingly in Crowden 
Clough, Cheshire 58, Professor Lindman thought might possibly 
prove to be Oxycoccus microcarpus Turczaninov. At Foulshaw Moss 
69, the Cranberry was associated with Andromeda Polifolia L. 
1693. Calluna vulgaris Hull var. Erikae Ascherson and 
Graebner. 
On the moors near Wessenden Head, Yorks, pointed out by 
Professor Graebner: near Honley, Yorks: also on Ben Lawers 88, 
but scarce at 2,800 feet; at Dunkeld, E. Perth 89: also on Urrisbeg 
near Roundstone, Co. Galway 16: at Killarney, Co. Kerry 2: and on 
the Lizard moors above Kynance, Cornwall 1. 
A handsome white-flowered form is cultivated in the Edinburgh 
Botanic Garden. 
This rooting prostrate plant with descending flowering branches, 
Professor Graebner says retains its character in cultivation at the 
Berlin Garden, 
1694. Erica cinerea L. The inflorescence of the Galway plant 
is much longer and finer than that of the British plant; about 
Roundstone it was particularly handsome. At Key Downs la form 
with very large flowers was seen. 
1695. E.Tetralix L. On the Lizard Downs 1, a very small 
flowered form was noticed. 
Erica Tetralix x vagans nov. hybr. Last year Mr. F.H. 
Davey, the very efficient leader of the party through Cornwall 
and the author of an excellent Flora of Cornwall (published J. of B. 
333, 1910), the description of a new hybrid heath, which had been 
found by the eminent horticulturist, Mr. P. D. Williams, of Lanarth, 
on the downs near St, Keverne 1, as E. vagans X cinerea, On the
