438 THE BOTANICAL EXCHANGE CLUB OF THE BRITISH ISLES. 
Since writing the above I have lieard from Dr. A. Thellung, 
of Zurich, the monographer of Lepidiiim. He has noted a recent 
' paper by Mr. Bucknall and myself in ‘Journ. Bot.’ (Bristol Plants); 
and points out that this plant is quite possibly the L. heterophyllum^- 
\a.r, papiUosum (Dunn) Thell. in ‘Journ. Bot.’ 1896, p. 477. Mr. 
Dunn’s note is instructive ; and, had I referred to it earlier, I should 
probably have gleaned Dr. Thellung’s idea independently. He 
suggests further the probability of More’s plant being really the 
same thing ; but as he has not been able to obtain a specimen the 
matter must stand over. — J. W. \Vhite. It has a very different 
habit and clothing from the Kingsthorpe, Northants, plant collected 
by Messrs. Jackson and Dixon in 1905 ; which Rev. E. F. Linton, 
in the ‘ Watson Exch. Club Report,’ determined as L. campestre, 
var. iongistylum, More. — E. S. Marshall. There is no doubt that 
my Lepidium is the papillosum of heteropliyllum and not a campestre 
form ; but Dr. Thellung has not yet sent a formal note on it. — J. W. 
White. With regard to the Kingsthorpe plant referred to, I may 
say that I cannot agree with Mr. Linton. My specimens were 
yellow-anthered Smithii, and lacked the characters which distinguish 
campestre. Whether Jackson’s plants were quite identical with mine 
I am not quite sure. I agree that these specimens are a Smithii 
form. — G. C. DrucE. I am inclined to name your plant L. hetero- 
phyllum (DC.) Benth. var. leiocarpum., Thell. {Monogr. 1906, p. 99), 
“ silicula laevis vel minutissime papillosa,” rather than v\v. papillosum 
(Dunn), Thell. l.c. p. 100, “ silicula papillis squamiformibus concavis 
distinctius asperulae;” as the papillae on the fruit of your specimen 
are not sufficiently prominent for the latter. I certainly consider 
the Z. campestre., var. longistylum, More (ex H. and J. Graves in 
‘Bab. Man. Brit. Bot.’ ed. 9 (1904), p. 38), to be really L. hetero- 
phyllum . — A. Thellung. 
Hutchinsia petrcea., Br. Dunes of St. Ouens on the Quenvais, 
Jersey, April, 1906. — G. C. Druce. 
Viola palustris, L. Coed P'ynnon, near Tandy Mill, Car- 
narvonshire, v.-c. 49, June, 1909. Miss C. E. Palmer gathered 
this plant many years ago in the locality, and when Mrs. Gregory 
saw the specimens in my herbarium, she thought there was a strain 
of epipsila in them. This too was the opinion of a foreign expert. 
I therefore visited the locality this June, in order to collect a series. 
They must, however, be referred to V. palustris, L. The leaves in 
some instances were of considerable size. — G. C. Druce. 
Viola hirta, L,, type. North Leigh, Oxon., v.-c. 23, May, 
1909. — G. C. Druce. Viola hirta, L. — E. S. Gregory. 
Viola arvensiSy Murr., var. subtilis (Jord.). Plantation, Slow 
Rd., nr. Ford, v.-c. 33, E. Glos., July 21, 1909. — H. J. Riddels-
