directly lie, much more rarely with a thin bed of alluvium 

 between them. If the weather is dry a slight breeze alters the 

 form of the hills, and a heavy gale can bodily shift them. To 

 such an extent is this perpetual motion the case on the coast, 

 that Glaucium flavum Crantz is quite rare ; I fear almost, if not 

 perfectly, extinct. I only know one collection, besides the 

 County Herbarium, where full-grown specimens in flower and 

 seed are preserved ; and they were all taken on the Lines, shore 

 by one hand more than thirty years ago. Lathyrus maritiinus 

 Bigel is another case in point ; it is a shingly beach species. If 

 it has not gone for ever, it is certainly over fifty years since it 

 was seen on the old spot at Ingoldmells, and nearer a hundred 

 I should judge from evidence I possess. Though there is almost 

 absolute proof of its former growth with us, generations of 

 eager botanists have sought it in vain, and I do not know of 

 a single Lines, specimen anywhere. Many long miles of coast 

 walking — they are long and thirsty in August — have not dis- 

 covered a spot where it is likely to be found, but as I have not 

 yet personally examined every locality I cannot abandon all 

 hope. Silene maritima - With. , whose boulder habitat has been 

 buried by sands east of Cleethorpes in my memory is a good 

 example; and Senecio viscosus Linn., met with for two seasons 

 in succession, is another typical instance. Where the latter can 

 be certainly located next season I cannot say, though I have 

 received it fresh from the coast from different friends, and 

 obtained the most exact topographical notes. 



It may easily be true that Weingcertneria canescens Bernh., 

 recorded in this paper as a casual colonist from the Norfolk 

 coast, is a native barely able to hold its own against adverse 

 circumstances. The rarity, however, of certain plants, which 

 are or may prove to be native on the Lines, coast, will not 

 explain the presence of a species like Euphorbia portlandica 

 Linn., which is a W. and not E. type, and must therefore be 

 classed as an alien, or of a foreign species like Iris spuria Linn., 

 so well established just inland. They are problems which to my 

 present knowledge appear insoluble.
