Otie Hundred and Forty-sixth Sitting. — Saturday, June 25, 1853. 

 Mr, Newman, President, in the chair. 



The President read the following communications : — 



Poiamogeton jiabellatus, Bab. 



"On the 30th of May last, 1 fomid this plant in a fen-ditch near 

 Nordelph, Norfolk. This may be worth recording, as the plant is very 

 little known, although probably not very uncommon. No botanist, 

 -who has examined and compared the earlier leaves of this plant and 

 P. pectinatus, can, I think, have any doubt concerning their distinct- 

 ness. When those leaves are wanting, as is usually the case when 

 the plant is in fruit, it is often very difficult to distinguish these spe- 

 cies." — C C. Babington ; June, 1853. 



Poiamogeton prcelongus, Wulf. 



" On May 30, 1853, I saw this plant in the river called Well Creek, 

 near Nordelph, in the fens of Norfolk. As this is a comparatively new 

 plant, the fact may be worth recording." — Id. 



Udora Canadensis. 



" Hitherto, Worcestershire and Gloucestershire have been exempt 

 from the inroads of the Udora ; but it appears that the insidious 

 floater is fast approaching, as I have just received a letter from a 

 botanical friend at Stratford-on-Avon (Mr. W. Cheshire, jun.), with 

 specimens ; in which he informs me that the plant has suddenly 

 appeared in the river Avon, at that place. He has perceived and 

 gathered it, this month, both above and below the town, as well as in 

 ditches near the bridge at Stratford, and, from his familiarity with the 

 river, and often boating upon it, is confident it was not there last year. 

 Now he finds it in the very bay where the boat is moored, ' every 

 inch of the water' about which, he says, was familiar to him. The 

 plants, though numerous, are mostly small, four or five inches in length, 

 and at present barren. He suggests, what I think is very likely, that 

 the winter floods, which were numerous and of long continuance,
