tity of Lepidium niderale growing, to the amount of several hundred 

 plants. About the same spot Spergularia marina was located in a 

 similar position. As an instance of enthusiastic zeal confirming 

 observation, T may mention that Mr. Thomas Westcombe, an un- 

 wearying botanist, who never takes anything for granted that he can 

 prove for himself, on hearing of this occurrence of the Lepidium, not 

 always to be found when wanted in our neighbourhood, set off on foot 

 for the spot one afternoon in the autumn, but was so late ere he could 

 reach the place that nothing could be seen ; but feeling about him 

 with his usual acuteness, he actually gathered the plant in the dark. 

 Whether the littoral plants thus noted here elected themselves such 

 a position from their love of saline matters, as hinted in Buckman's 

 ' Straits of Malvern,' or whether their seeds had been conveyed with 

 the rubbish, I must confess I feel rather dubious about. Lepidium 

 ruderale is probably always present somewhere in the Droitwich dis- 

 trict, but it never stays long in a place. 



Some dissatisfied persons may possibly object to these migrations 

 of plants, and think their doings unworthy of record unless they stay 

 where they appear. Well, they do sometimes, though it is not gene- 

 rally to be expected ; and I have one case at least, though I expect 

 careless compilers, uot anxious about anything that does not come 

 close under their own eye, will take no notice of it. Eight years ago 

 I recorded the appearance of Lepidium Draba on the then recently- 

 made embankment of the road in connexion with the new iron bridge 

 at Powick. It had never previously been observed in Worcestershire. 

 There, however, the Lepidium has continued in tolerable plenty year 

 after year, and there it remains at the present time. 



Cardamine impatiens is generally accounted a rare plant in floras, 

 and does seem to be very local. It is present, however, in many of 

 the woods on the banks of the Severn, and where any new quarry is 

 opened in the sandstone it starts up among the rubbish with singular 

 rapidity. Soon after the new works of the Severn navigation were 

 made at Lincomb, near Stourport, four years ago, the banks of the 

 river became covered with it all about there, and quite a shrubby 

 coppice of the plant existed in 1849. From the quantity of seed the 

 C. impatiens produces it might indeed be expected to be very plenti- 

 ful in its habitats, but this is not the case, unless where the soil has 

 been newly turned up. 



The statement of an experimental agriculturist, a worthy friend of 

 mine, well exemplifies the storing up of seeds in the ground for future 

 economical supply, and the exuberance with which they vegetate
