SUPPLEMENT TO NOTES. ON RUBI.—No. a 
By Cuartes C. Banineron, M.A., F.R.S. 
As the publication of my paper, ‘Notes on British Rubi’ (Journ. 
Bot. xxiv. pp. 216 and 225), has brought under my notice several 
new forms which require attention, I think it well to publish them 
seems to me to be our duty now to identity and define our oe 
as the great continental botanists have done. Genevier published 
no attempt to define aggregate — neither did P. J. Miller ; 
and Focke has only partially done so. Even our groups must be 
considered as artificial. In Nature ihe affinities are of course not 
linear manner, but spread in a ¢ circular, if not 
Ww ecessarily to 
them in a linear series, and therefore sometimes to separate plants 
far from some of their apparent allies. I need not take up space 
by further notice of this difficult subject here, but will proceed to 
the description of the recently observed forms, three of which can be 
identified with much certainty with plants a ee by — ; 
and the other has been long known to me, but has now firs 
separate specific name given to it. I doaneibo it as follows :-— 
1. R. Newsovutpn Bab.—Stem slightly arching, angular up- 
wards, subglabrous ; prickles unequal, large, conical, fir: from a 
large compressed base, much exceeding the many short aciculi and 
sete ; leaves 5-nate or 3-nate; leaflets very finely but doubly dentate, 
green, and not felted beneath ; terminal leaflet broadly quadrangular- 
obovate, cuspidate, subeordate below ; panicle long, its ultra-axillary
