The locality, where it was first found, is by a pool ; it grows on the 

 damp sandy margin with Hydrocoty^.e, Ranmiculus Flammida, MiUegrana, 

 Ih'osera, Veronica scutellaia, Juncus hulbosus, &c. No other introduced 

 vegetation is near, except that it is in a district in which Pines and 

 Rhododendrons are planted. The late Mr. J. Walter of Bearwood (on 

 whose estate it occurs) told me he was not aware of any introduced 

 soil being us:ed in the vicinity. Subsequently I found it in consider- 

 able abundance, and it appeared as if the Illecebrum had been covered 

 with sand brought from the neighbourhood in order to raise the 

 ground for the road, and had eventually found its way through, as it 

 did not appear during the first two years, and then showed itself at 

 the margin of the sand. I may say that early in the year previous to 

 its discovery I had searched the borders of the pond for MiUegrana, but 

 did not go completely round it, and so missed the locality by a few yards. 



The original record of this plant as ' common in waste places and 

 by roadsides at Blewbury and tlironghout the Vale,' by Mr. J. Lousley in 

 RusselVs Cat. 1839, is certainly an error. Probably Polygonum aviculare was 

 mistaken for it. 



The plant is only recorded from Cornwall and Devon in Great Britain, so 

 its occurrence in Berkshire is of singular interest.
