12 Harrison: Wild Roses of Durham. 
thrown upon the occurrence of this form in Durham 
by certain writers, uniserrate forms which can only 
be referred to this do occur with us at Billingham 
(VII) 
m. pseudo-mollis J.G. Baker. Almost typical plants but 
with larger leaves than this form demands occur 
on Birtley Fell (Ia.) 
m. cuspidatoides Crep. Sparingly throughout our area. 
m. Sherardi Davies. Once, West Cornforth (IV.) ; two 
or three plants growing together Wreckerton (Ia.) 
m. scabriuscula Winch. (III.) Langley Park, Waldridge. 
m. emimens Harrison. This is a new form which I 
described in the Octeber Vasculum from Wolsing- 
ham (II.); it also occurs (III.) Satley and Lan- 
chester. 
ROsA OmIssA Deés. 
m. vesimosoides Cr. Thinly distributed, but not un- 
common in the western divisions. Rare at Wal- 
dridge (III.) ; Billingham (VIT.) 
m. submollis Ley. Nearly the same, leaves eglandular, 
Wolsingham (IT.) 
ROSA VILLOSA L. 
Quite common in the west ; rare elsewhere. 
m. caeritlea \WWoods. Rare Beamish (Ia.) 
ROSA POMIFERA Herrm. 
A single and quite typical plant in a hedge between 
Greatham and Cowpen Bewley (VII.) Near a 
arden and possibly an escape. 
PIMPINELLIFOLIZ. 
ROSA SPINOSISSIMA L. 
m. pumpinellifolia L. (II.) Sparingly everywhere ; (III) 
Rare; (IV.) Very common in the coast denes, 
thins out inland ; (V.) Falcon Clints. 
PIMPINELLIFOLIAZ x VILLOSA. 
ROsA INVOLUTA Sm. 
Form. Sabint. Sparingly Horden, etc. (IV.) 
PIMPINELLIFOLIZ x EUCANINA. 
ROSA HIBERNICA Templ. 
This hybrid occurs near Haverton Hill (VII.) but for 
the same reason as recorded under Rosa glauca, I 
cannot be sure of the exact form. There are 
several plants growing close together in a hedge 
which to judge from their foliage and armature 
must have the parentage assigned to them above, 
but they never flower. If my judgment is correct 
then the parentage will be Rosa spinesissima x R. 
glauca. 
The list given above represents the work of one individual
