the beach at Studland, in considerable abundance. I have heard of 

 other localities for one or other species, but can say nothing positive 

 concerning them. 



In conclusion, I would observe that certain questions remain to be 

 settled. Which form is the ipsissima Filago germanica of Linnaeus ? 

 What is really the F. pyramidata of Linnaeus ? Is the Filago erio- 

 cephala of Gussone distinct from the F. canescens of Jordan ; and if 

 distinct, have we both these latter in England ? Are the F. spatulata 

 and F. apiculata distinct from each other, and from the plant usually 

 representing F. germanica in English herbaria ? Lastly, what are 

 the localities or general distribution of the two former in England ; 

 namely, of F. spatulata and F. apiculata ?

P.S. Since sending the notes on Filago germanica, and its allies, I 

 have been enabled to examine the Linnean herbarium, re-opened after 

 the cleansing vacation. F. germanica is there represented by three 

 specimens, on different sheets. One of these, marked " germanica " 

 in the handwriting of Linnaeus, is our ordinary plant so named. A 

 second is apparently F. spatulata. The third, marked " pygmaa " by 

 Linnaeus, and altered with pencil to " germanica " by Smith, is a dis- 

 torted plant, probably belonging to F. spatulata also ; certainly not 

 Evax pygmaea. I find no F. pyramidata in the Linnean herbarium.

Occurrence of Equisetum hyemale and E. umbrosum in Northum- 

 berland. By Joseph Sidebotham, Esq. 



It may be interesting to some of your readers to know that Equi- 

 setum hyemale and E. umbrosum are found in abundance on the 

 banks of the Coquet, near Felton, Northumberland, and also near the 

 celebrated hermitage of Warkworth. Of the umbrosum I dried a few 

 barren fronds, to which any of your readers are welcome.
