1857.] BOTANICAL NOTES, NOTICES, AND QUERIES. 303 



habitants call it Samphire, and in my early botanical days I looked more 

 than once for the umbel of white flowers, and of com'se was as often disap- 

 pointed. W, F.

Common Plants. 



I find that there d.XQ fifty-six in your " List of Common Plants " which I 

 have not observed in Lincolnshire. This is better than Mr. Stowell's 

 eigJdy-six. There are five or six or more in yom- list which grow very 

 sparingly with us, and several which are anything but common. 



Digitalis piirjmrea disqualified a collection of wild flowers at Lincoki, 

 because not a Lincolnshire plant, — whether rightly or not, I cannot say. 

 I have never seen it in the county, and I have scoured our part well. It 

 is veiy common in Torkshii-e. W. P. 



[What will Mr. Watson say to this ?] 



Agrimonia Agrimonoides. 



There is a plant, which was so called by Linnaeus, but which has now 

 been long considered as a distinct genus, and named Aremonia agrimo- 

 nioides. It is a native of Austria, Italy, Greece, and Turkey, and therefore 

 very unlikely to be indigenous in Scotland. I should be much obliged to 

 Mr. Sim if he coidd send me a specimen of the Scottish plant for exami- 

 nation. C. C. Babington. 



Senecio paludostjs. 



On the 11th of last August I saw the Senecio pahidosus groAvin^ in„a 

 Avildpaxt of the fen between jQambridge and Ely. It was certainly npiiy.Q. 

 there^although, small in quantity. The flowers were then over, but there 

 could be nocloubt concerning the species. As the plant has been supposed 

 to'TJe Tost in that county, this fact may be worth recording.

Disease in Peuit-trees. 



I should be very glad if any of your con'cspondents could teU me whe- 

 ther they have noticed the following disease in fruit-trees, or can account 

 for it in any other way than I have been led to do. This disease, which 

 in a few months disfigures and maims the most healthy trees, appears in 

 the following way, as far as I can judge from the veiy short time during 

 which my attention was turned to it. The branches first become fi'eckled 

 with chaffy specks, some one or two of which become enlarged, and, seem- 

 ingly, eat into the stem ; this rapidly corrodes, and after a short time the 

 bark is destroyed all round, and the branch above this point of course dies. 

 In this way a Pear-tree, left for the pur}30se, was killed in about a year and 

 a half. If the branch be cut at the commencement of the disease, a brown 

 tinge may be noticed between the alburnum and the wood, and when it is 

 far advanced, the rusty-red colour spreads all aroimd. Prom the situation 

 of the trees, and experiments made in changing the soil, I have supposed 

 that the cause of the disease was the too great prevalence of oxide of iron 

 in the gravel below : in every case of disease the roots of the trees had
