Rosa Sabini var. In the valuable collection of roses, made by 
the late Mr. Robertson, and now kept in the Newcastle Museum, 
there is a plant marked “ Rosa involuta, 2nd variety, Ouseburn.” 
The Ouseburn which is meant is, I presume, the stream of 
Heaton Dene, and I fear the plant is now eradicated. Like the 
late Mr. Winch, I do not think that &. cnvoluta is fairly to be 
separated as a species from &. Sabini. There are authenticated 
specimens of the true &. involuta in the same collection, sent by 
Mr. Borrer, from the Cambridge Botanic Garden. The true R. 
involuta has the upper side of the leaves glabrous, the lower 
hairy all over, glandular principally on the edge, some of the 
teeth simple andsome with one or two accessory gland-tipped 
serrations, a very prickly subglobose calyx-tube, and undivided 
glandular and setosociliated sepals. The Ouseburn plant comes 
nearer a Belgian form, the F. subnuda of Crepin, than anything 
else I have seen in England. The leaves are hardly at all 
hairy above, and on the underside they are hairy principally on 
the midrib, and but slightly ciliated along the edges. The ser- 
rations are fine and sharp, but usually double; the peduncles 
very prickly and setose, but the calyx tube is dark purple and 
glaucous, and almost entirely destitute of prickles and sete; the 
leaf-pointed, glandular sepals being slightly compound, and in 
the specimen preserved the flowers are four in number, and the 
lateral peduncles are furnished with lanceolate setoso-ciliated 
bracts. I wish the plant could be found again. 
Rosa canina, varieties. Three Northumbrian forms of this 
very variable plant appear to merit attention. The first was in
