oleifolia , Sm., is identical (as appears probable) with the hybrid lutescens, 
A. Kern., it must, of course, be dropped from our lists as a var. of 
A. cinerea ; but if it is not, why retain it and give it a special name 
more than any of the many other forms (not true varieties) of 
A. cinerea ? The multiplication and retention of varietal names for 
slight modifications has been the bane of salicology.” — F. Buchanan 
White. 
Salix cinerea , L., c. oleifolia , Sm. Near Bournemouth, Dorset, 
6th April and 25th September, 1891. — E. F. Linton. “Very near 
A. cinerea , but I am inclined to think that it may be a form of x A. 
lutescens , A. Kern., to which oleifolia , Sm., seems to belong.” — F. 
Buchanan White. 
A. cinerea , Linn, x repens , Linn. Cult. Origin : Armadale, 
Sutherland, May and August, 1891. Dr. White thought Caprca rather 
than cinerea one of the elements in this hybrid. I have retained the 
name on the labels which I first applied to it, as cinerea and repcns 
were growing near and there was no Caprea to be seen. The present 
specimens should declare the parentage. — W m. R. Linton, “x A. 
ambigua , Ehrh., near repens .” — F. Buchanan White. 
A. aurita , L. x viminalis , L. Cult, from Holme, Hunts, May and 
July, 1891. — W. R. Linton. “ One of the numerous forms of the very 
inconstant x A. Smithiana. It is not improbable that A. aurita may 
be one of the parents, A. viminalis however preponderates.” — F. 
Buchanan White. 
A. aurita , L. x A. Smithiana, Willd. Near Shirley, S. Derbyshire, 
May and August, 1891. — W. R. Linton. “ It is difficult to know what 
to call this plant. In everything except the long styles it is x A. 
lutescens , A. Kern. Perhaps (as I suppose Mr. Linton means to 
suggest) viminalis has been a remote ancestor and left its marks on 
the styles and stigmas.” — F. Buchanan White. 
A. aurita , L. x cinerea , L. Cult, from Holme, Hunts, May and 
July, 1891 ; and near Shirley, South Derbyshire, 5th May and 5th 
August, 1890. — W. R. Linton. A. aurita- ci?ierea (on the cinerea side). 
Cult, from Holme fen, Hunts, 4th May and 20th September, 1891. — 
E. F. Linton. “The three = x lutescens, A. Kern.” — F. Buchanan 
White. 
A. aurita, L. x Caprea, L. Near Shirley, S. Derbyshire, 13th 
May and 30th August, 1889. — W. R. Linton. “Very near A. aurita. 
The Caprea element is doubtful, but there are some indications of it. 
This is one of several curious forms or hybrids of A. aurita which 
Mr. Linton has found in Derbyshire.” — F. Buchanan White. 
A. Caprea , L. x nigricans, Sm. Clova, Forfarshire, 20th July, 
1890. — W. R. Linton. “Very near A. nigricans, but the leaves (which 
might be better) suggest a strain of CapreaS — F. Buchanan White. 
A. nigricans, Sm. Glen Fiagh, Forfarshire, 15th July, 1890. — 
W. R. Linton. “Two specimens. Seems to be nigrica?is , but good 
leaves wanting.” — F. Buchanan White. 
A. nigricans, Sm. x phylicifolia, L. Fortingal, Perthshire. — W. R. 
Linton. “Catkins bad, and no good leaves, but it may pass for this 
intermediate.” — F. Buchanan White.
