GEUM 187 



The foregoing list of Berkshire Brambles owes what degree of completeness 

 it possesses to the work of my friend the Kev. W. M. Rogers, whose know- 

 ledge of the British forms of this critical genus is probably unsurpassed. 

 He has paid three separate visits to Berkshire, when the Brambles were 

 made a special study, but in addition to this personal work he has, with 

 unwearied kindness, examined my rather bulky gatherings of the last few 

 years ; indeed, with the exception of R. rhomhifulius and R. mucronatiis, he 

 has had all the species in my list under his notice. Few county lists, there- 

 fore, have the same degree of unity of nomenclature. In my earlier years' 

 collecting I owe much to my friend Dr. Focke of Bremen, for kindly naming 

 specimens ; he has also visited Boar's Hill, that very^ interesting locality to 

 the batologist, when he discovered the rare R. sulcatus. This opportunity is 

 gladly taken to oflfer my sincere thanks for the kind assistance genei'ously 

 given me by these well-known authorities. The Rev. W. M. Rogers' Key to 

 British Rubi originally appeared in the Journ. Bot. Apr. 1892 to Feb. 1893.

The Avens is too common to need an enumeration of localities. A 

 form with seven petals has been seen in several places, and a larger 

 flowered plant was seen by the Cole near Strattonborough Castle. 



The roots have an odour somewhat resembling cloves, hence the 

 name used by Gerard, &c. The outline of the leaves reminds one 

 somewhat of Smymium. 



Geum urbanum occurs in all the bordering counties.
