Sept. 1, 1917. I sent this out as var. papillosum , but now believe 
it is var. canescens (Gren. & Godr.). The ‘papillae’ were very 
noticeable when the specimens were gathered, but are much less so 
in the dried plants. In all the dried material of var. canescens I 
have examined the scales can be seen with a lens. Apparently 
the scales stand out from the pouches at certain stages of growth, 
perhaps owing to turgidity of the basal cells, and are closely ap- 
pressed when the latter are dry. If this is so, the scales are not 
a reliable character for discrimination between L. campestre and 
canescens , and the var. papillosum should disappear. Dunn’s 
diagnosis of Lepidium Smithii, var. papillosum in “ Journ. Bot.”, 
1896, p. 477, is as follows: “Pouches more or less rough with 
papillae, usually smaller but often not less numerous than those 
of L. campestre. The prevalent, if not the only, form in some 
districts.” — W. C. Barton. As far as these specimens are con- 
cerned, the varietal character seems very slight. — E.S.M. I do 
not think the silicles are papillose enough in these specimens to 
bring them under the papillosum of Dunn, as understood by 
Thellung. Mr. Barton’s example agrees with a specimen Dr. 
Thellung named for me : “ var. leiocarpum — silicula laevis vel 
minutissime papillosa.” — C.E.S. 
Viola epipsila Ledeb., f. glabrescens Asch. and Graeb. (Jide E. S. 
Gregory). Stow Bardolph, W. Norfolk, v.c. 28, July 30, 1917. — 
J. E. Little. My specimens have the leaves and stems quite 
glabrous. The bracts are about the middle of the peduncle (not 
above it). The sepals, though oblong in shape, are very blunt, 
and hyaline-bordered. I believe this to be V. palustris. — E.S.M. 
The specimen sent me by Mr. Little, gathered at Stow Bardolph, 
and which I named Viola epipsila, f. glabrescens , differs from the 
one described by Mr. Marshall. It has thinly scattered hairs on 
the upper and under surfaces of the leaves, and bracts above the 
middle of the peduncle. The sepals are less pointed than usual, 
but this is a variable character, as is also the position of the 
bracts. Wherever V epipsila occurs in our country or Ireland, 
intermediates, or hybrids between it and V. palustris, are to be 
found. — E.S.G. 
V. odorata L., forma. (Ref. No. 1230). Lane, Beach, near 
Bitton, W. Glos , v.c. 34, April 21 and June 30, 1917. Lowest 
petal in some cases emarginate ; peduncles with spreading hairs. 
— Ida M. Roper. I think probably my new variety of V. odorata 
— rubra-purpurea. — E.S.G. [Later] The particular characters of 
var. rubra-purpurea, as copied from my notes are : “ FIs. rich red-
