Those marked thus * mostly affect calcareous soils. 



Now, imperfect as is this list, both in arrangement and specific 

 definitions, yet it is clear enough to convey to the mind of the 

 working botanist, that here is an allocation of plants scarcely to be 

 met with elsewhere in the same space of ground. Many of them 

 are doubtless there in virtue of the calcareous nature of the soil ; 

 every species of the list, if we except the Jasione montana, L., being 

 more or less common to the oolitic limestone series of the Cottes- 

 wolds ; and yet we must range those hills from end to end to find 

 all the species here met with in a single month, on an isolated hill, 

 and that too an artificial structure. 



That these facts will come out all the more strongly with a 

 perfect list of the Flora of Silbury Hill I have no doubt ; and it is 

 the hope that some of the good botanists of the Wiltshire Society may 

 be induced to a "further examination of this interesting monument 

 that has induced me to offer these few short notes,
