Sprowston, Norfolk, in 1885, and was described by him in the " Journ. of 
Botany,” 1887, p. 82, as R. lucens, but this name being already in use, 
Dr. Focke renamed it after Linton 4 . Writing in 1893 5 Rogers says, “ A 
small, well marked plant ; still, I believe, only recorded from the Rev, 
E. F. Linton's two Sprowston localities, Norf.” 
Two Irish specimens are of interest: 
R. myricae Focke, v. hesperius Rogers. 
This form was regarded by Rogers as a species or variety and was 
described by him in 1896 6 . He says, " This is the bramble referred to 
by Messrs. Marshall and Schoolbred, its discoverers .... a 
striking plant found at Oughterard, Maam, Clonbur and Cong.” 
The specimens in the Herbarium bear the label of E. S. Marshall and 
were collected at Clonbur, W. Galway, 12. vi. 1896. The label is marked 
“ (confirmed by R.) ” and bears the stamp of the Watson Botanical Ex¬ 
change Club. 
R. Drejeri G. Jensen., subsp. hibernicus, Rogers. 
The type was described by Rogers 7 , and was received from “ Revs. 
C. H. Waddell and H. W. Lett from Saintfield and Aghaderg, Co., Down. 
Collected' 1894-5.” 
A specimen sheet in the Herbarium bears the inscription, " thicket, 
Saintfield, Co. Down, 3 Aug. 1895 (fide W. M. Rogers.),” and is stamped 
Watson Botanical Exchange Club. 
A specimen in the Herbarium with a label in the handwriting of Powell 
bears the inscription, ” R. Koehleri v. pallidas ? Bab. Woolpit Warren 
(open ground) W. Suffolk, 5 Aug. 98.” To this is added a note in Rogers' 
caligraphy. “ Yes, I think, certainly pallidas, Bab. which I am thinking 
of describing afresh and calling R. dasyphyllus some day soon. W. M. R.” 
The idea was apparently carried out, for in the Appendix to Babington's 
Manual ” the form is named R. Koehleri Wh. subsp. dasyphyllus, Rogers. 
Another series of 28 sheets of Essex Rubi was presented to 
the Museum by Mr. C. E. Britton, in illustration of his paper, 
entitled “ South Essex Brambles.” 8 These are incorporated 
with the general collection of Rubi. 
The matter of classification and nomenclature raised con- 
•siderable difficulties in arranging the collection, but after care¬ 
ful consideration it was decided to adopt that given by the Rev. 
Moyle Rogers in his “ Handbook of British Rubi,” and inserted 
as an appendix in Babington’s “Manual of British Botany,” 
9th Ed., 1904. Out of 176 species and varieties given in this 
list, 118 are represented in the Museum Herbarium, and it is 
hoped that students of this difficult group will avail themselves 
of the well authenticated specimens in the collection.
