name of mucronatus, as applied to the present plant. As long ago 
as 1840 Torrey and Gray showed that the North American R. 
mucronatus Seringe was a mere synonym of R. triflorus Richards. 
very clearly-marked type, and although it is widely spread in 
Scotland and the Northern and Midland Counties of England, 
I have never seen it from the South of England or from any 
Continental locality. Years ago, in company with Dr. Boswell, 
I collected along with the type in Arran a strongly aciculate variety, 
caring the same relation to the type that adscitus and derasus bear 
to villicaulis, and vestitus to leucostachys. R. Grabowskii Bab., not 
W. &N. (Bloxam’s plant), should be compared with R. horridicaulis

Vosges,’ No. 14 bis. The place of this is, I think, between pubescens

_ 21. R. tomentosus Borckh. — I had the opportunity for the first 
time this autumn of seeing this growing plentifully in the Valley of 
the Neckar, above Heidelberg. The type is a most distinct plant, 
but it appears to run off into other things in all directions, and to 
complicate the German brambles in a way that we are than to 
be spared from in England. It appears to be essentially a dry 
country type, needing greater heat in summer than we get in 
England.” It reaches, however, Belgium and Brittany, so that it 
Should be looked for in the chalk-districts of the South of England.
