although the limits of this species seem to be very uncertain.” It is 
in a very aggregate sense only that I feel able to apply this name 
as yet. — W. M. R. 
Rubus foliosus , W. & N. St. Leonard’s Forest, Holmbush, Sussex, 
18th August, 1892. — J. W. White. Yes. — W. M. R. 
R. ? Edwin Wood, Herefordshire, 27th June, 1893. 
Petals narrow, white, whitish stamens equalling whitish styles. — 
Augustin Ley. This appeared to me hardly to differ from the 
Beacon Hill (Monmouthshire) R. serpens , except in being more 
densely aciculate ; and now Dr. Focke has named it simply “ R. 
serpens, Weihe.” — W. M. R. 
R. ? Linton Wood, Herefordshire, 20th July, 1893. 
This very well marked plant has been (I believe in 1892) sent by 
Rev. W. M. Rogers to Dr. Focke ; and Mr. Rogers told me was 
considered by him a form of R. hirtns. I am not satisfied with 
this.— Augustin Ley. “ Near the continental R. hirtus, W.K.” was 
Dr. Focke’s suggestion to me in 1892. If indeed it belongs to that 
group, it is certainly a very remarkably large-flowered and strikingly 
handsome member of it. — W. M. R. 
R. ochrodermis , A. Ley. Woods, Dinmore, Hereford, 22nd Sep- 
tember, 1892 ; Whitney, Herefordshire, 26th July, 1893. See ‘ Journ. 
Bot.’ 1893, p. 15. I have found this plant in four or five fresh stations 
in Herefordshire this year. — Augustin Ley. 
R. ? Near Bangor, July, 1893. I cannot get a satisfac- 
tory name for this from either Dr. Focke or Rev. W. M. Rogers. It 
is rather common about here in many places. — J. E. Griffith. An 
interesting-looking plant claiming careful further study. — W. M. R.
