Ill 
occitanicum, from which it differs in the entire margin of the 
leaves and in the rounded lobes of the fruit. Of the British 
forms of alpestre it resembles most closely T. silvestre Jorch, 
far more so than does the Llanrwst plant. It differs however 
in its long style and smaller fruits, and may perhaps best be 
regarded as a definite variety of silvestre. I do not think 
this and the Llanrwst plant are identical. — E. Drabble. 
Both Mr. Fraser and Mr. Pugsley would tentatively refer 
this to T. silvestre -lord., and Mr. Pugsley adds “ but the 
British forms of this group need further investigation.” 
Helianthemum Chamaecistus X polifolium. Purn Hill, 
Bleadon, N. Somerset, June 22, 1931.- — H. S. Thompson, 
who first found it there with both parents in July, 1888, 
(and recorded the fact in the Nat. Hist Journ., York), some 
six weeks before the late David Fry independently discovered 
polifolium there in September, and recorded it in Journ. Bot. 
188S, 313. Possibly it got established at Purn Hill by the 
agency of birds from Brean Down, three miles distant. — 
H. S. T. 
Helianthemum polifolium Miller. Purn Hill, Bleadon, N. 
Somerset, June 22, 1931. Too late for good flowering 
specimens. Mr. Lousley reports that his sheet is the hybrid, 
so probably one of the labels got wrong. — H. S. Thompson. 
Viola . [939 A]. Stubble, Hundred acre field, St. 
Ippolyts, Herts, May 18, 1931. — J. E. Little. V. variata 
Jorcl. var. sulphurea Drabble (a few with some little colour 
in the upper petals). — E. Drabble. 
Viola . [C 35/0]. Sandy field, near Loddon 
Bridge, Berks, May 24, 1931. — J. E. Lousley. Though even 
less hairy, this cannot be separated from the plant sent to 
this Club in 1927 from Burghfield Common, Berks. [Y 129] 
labelled V. arvatica by Mr. Lousley, which I then pointed out 
was not arvatica but V. vectensis (Report, 1927-28, p. 425), 
though it in turn was less hairy than the Isle of Wight plant 
on which V. vectensis was founded. The large flowers, of 
course, at once distinguish these plants (C 35/0) from 
Deseglisei, for small specimens of which they might otherwise 
be mistaken. — E. Drabble.
