the river, below the town, where it seems likely to become as great a 

 nuisance as it is in Cambridgeshire. Its habitats are thus advanced 

 from the Derbyshire border, at Burton-upon-Trent, to the centre of 

 the county. Our dirty little stream (aptly named the Sow) flows into 

 the Trent ; so that the two localities have a very direct water-commu- 

 nication with each other. How it was introduced here, I cannot 

 ascertain. Its existence so near home was unknown to me until yes- 

 terday, when, taking a botanical stroll with a friend, this remarkable 

 addition to our local Flora came under our observation." — R. C.

Udora Canadensis in the Valley of the Severn. 



" While taking a botanical stroll, yesterday evening, I found a small 

 patch of Udora Canadensis, in a pool near the river Severn, but 

 unconnected with it, except by floods, near Bevere Island, about 

 three miles from Worcester, up the river. I believe this is the first 

 time it has been found in this district, though it was discovered in 

 this county, in the Avon, at Evesham, in June last, by Mr. W. Che- 

 shire." — Thomas Baxter.

" I beg to enclose a frond of what I believe to be the true Lastrea 

 rigida. I found a single plant, bearing only four fronds, in a some- 

 what bleak and exposed situation, within a few miles of Bath. I 

 searched diligently for other plants, but without success." — John E. 

 Vize ; Town Mills, Bath, September 19, 1853. 



The President, without hesitation, pronounced the frond which was 

 exhibited to be Lastrea rigida, and in no way distinguishable from the 

 same plant as found near Settle, in Yorkshire. 



Worcestershire Naturalists' Field Club. 



Meeting in Wyre Forest. 



A meeting of this Club took place in the latter part of August, 

 within the shady coverts of Wyre Forest, under the Presidency of the 

 Rev. Canon Cradock. " Stately Wyre " has been celebrated in the 

 strains of Michael Drayton, and its venerated sorb-tree is noticed in 

 the ' Philosophical Transactions,' for 1678. The party were anxious 

 to examine the old Pyrus domestica, or true service-tree, the only one
