distributed much resembles a Reseda from Wytham sent in 1906 
by Mr. Druce and named by him R. stricta, Pers. — H. J. R. 
Yes, Reseda stricta, Pers. This species belongs to that section of 
Resedastrum in which the calyx is caducous and seeds smooth 
or nearly so. — E. G. Baker. 
Viola Riviniana f. minor, Murbeck, = V. flavicornis, Forst. 
Clogher, Co. Tyrone. Coll. Miss Peck, April and May 1907. — 
E. S. Gregory. 
V. canina, L. Railway Bank, Malvern Link, Co. Worcester, 
30th July 1906, and iith June 1907. — S. H, Bickham. I do not 
think that this is pure canina^ “ Linn ” ( V. ericetoriini, Schrad.), but 
probably a hybrid with V. Riviniana. — E. S. M. I suppose this 
to be V. silvestris, Reich., of rather diffuse growth. — D. Fry. 
I have no hesitation in giving my opinion in favour of the hybrid 
Viola Riviniana X ericetonim. It is a plant I know pretty well, 
as I cultivated it for years in my garden at Weston-super-Mare. 
Mr. Beeby very kindly named it for me in 1898, and I have taken 
a good series of specimens for my herbarium ; one of which, 
gathered late in the season, is almost the counterpart of Mr. Bick- 
ham’s example. — E. S. Gregory. Mr. Bickham subsequently 
wrote to Mrs. Gregory : — “ I think that .... we may have on this 
railway bank V. Rivhiiana, V ericetonim, and the hybrid V. Rivini- 
ana X ericetorum, all growing together. Towndrow writes that he 
used to think he found — 
1. True canina (ericetorum). 
2 . V. Riviniana. 
3. A doubtful plant which he then supposed to be V. Rivini- 
ana X ericetorum, but could get no one to agree with him.” 
V. canina x Riviniana. East Pentire, Newquay, West 
Cornwall, v.-c. i, i6th May 1907 (with Mr. F. H. Davey), and 
14th July 1907. This was first identified in 1905 by Mrs. E. S. 
Gregory, who kindly wrote, “ I take (it) to be a hybrid between 
canina and Riviniana,'^ but reserved a definite opinion till seeing 
full material, which illness prevented me sending the next year. 
This year I sent it to Mr. E. Baker, who kindly forwarded it 
to Dr. Becker, who replied that he believes the plant to be 
canina x Riviniana. Mr. Baker says that in most of the sheets 
of this hybrid in the British Museum the leaves are rather more 
cordate at the base than in my plants ; he does not give a positive 
opinion ; and says that Mr. Pugsley does not think there is any 
Riviniana in it, and would call it a form of ericetorum. The plant 
forms a small group of large, very compact tufts, the largest, nearly 
3 ft. in diameter, having been lately destroyed by quarrying oper- 
ations. No root-leaves can be seen. On 28th June, I collected
