TWO LINCOLNSHIRE PLANTS. 
No satisfactory explanation has as yet been given why 
Limonium bellidifolium Dum. has disappeared from the estuarine 
alluvium on the Wash in South and North Lincolnshire while it 
still remains in Norfolk, in both the east and west Watsonian 
ORO on the same estuary. r. A. Bennett says (Trans. 
Norf. and Norwich Nat. Soe. viii. 935) : “The Norfolk stations 
must be as old as the Lincoln, yet it there maintains its ground. 
They are far older and less fluctuating, and that is the whole 
oe agriculture. ‘It grows,” says Sir Soe bite Bet Guide, 
up at once, or harrowed aa as a bE for grass and 
move seed for = mapedowing the salt out of the silt. In either 
Estuarine sand is ae cast up welcome the new bank by its 
action on the cross currents of the estuary; but years of Sali- 
cornia, Atriplex portulacoides, and later aire of growths 
on the foreshore have to act as a silt-sieve on the turbid waters of 
~ estuary to prepare for L. bellidifolium a fitting home ere it 
an come to stay. This even is not all. Sheep, or other closely 
biting stock, must come and lend their aid to advancing the 
proper conditions, or they will never be what are required. 
These ses are the romances of the rock-soil method. The 
driff maps of the Wash conclusively show that the inclosures on 
the Lincolnshire side have been far more extensive than any made
