Arabis hirsuta Scop., [near] var. glabrata Syme. Origin, 
Plumpton, W. Sussex, v.c. 13, 1913. Hort. Reigate, June 1916. 
I have hesitated to label these plants now distributed “var. 
glabrata Syme,” as that author definitely states (“E. B.” ed. 3, 
166-7, 1863) that his variety should have “stem and leaves 
smooth, or the latter more or less ciliated at the margins.” It 
will be noted that in these specimens, whilst the leaves are prac- 
tically glabrous, the stems are decidedly hairy. I think, however, 
it will be found that “var. glabrata ” may be satisfactorily distin- 
guished by the peculiar shape and colouring of its root-leaves 
(besides the fact of their being glabrous, or almost so), and that 
the original diagnosis should possibly be amended to include the 
hairy as well as the glabrous stemmed plants (B. E. C. Rep. 1916, 
556). The basal leaves of A. hirsuta shown in “ E. B.” IX. t. 587 
(1799), and Coste, “FI. Fr.” I., p. 100 (1901), may well be com- 
pared with those of the Plumpton plant. In B. E. C. Rep. 1916, 
556, the question is raised as to the best distinguishing characters 
of A. ciliata Br. and A. hirsuta Scop., var. glabrata Syme. Messrs. 
Pearsall and Lumb mention the ripe pod and seed features 
emphasised by Syme ( l.c .), and through the kindness of Mr. 
Barton, who sent me some ripe seeds of the Dog’s Bay A. ciliata , 
I have been able to see clearly the differences in size and shape 
of the seeds of these two species. When Mr. Barton’s seeds 
germinated, and I was able to compare the young rosettes with 
those of A. hirsuta , var. glabrata , other differences came to light, 
and these seem worth putting on record. In general colour the 
rosettes of A. ciliata are blue-green, in the other yellow-green. 
In the former the leaves are practically glabrous above and 
below, except for rare simple and bifid hairs at margin (usually 
at tip and at teeth apex) and on petiole ; in A. hirsuta, var. 
glabrata the leaves are similarly practically glabrous on both 
surfaces, but there are occasionally a few scattered simple and 
bifid hairs on the margin and on the upper surface near the tip. 
As regards the shape of the blade, this is much broader and 
blunter at the tip in A. ciliata than in the other plant (circa 
13 — 19 mm. long by 10 — 13 mm. broad in ciliata, c. 13 — 19 mm. 
long by 6^ — 10 mm. broad in hirsuta, var. glabrata), and thus 
more orbicular in outline, and reminding one strongly of the 
leaves of the Daisy. — C. E. Salmon.
