Arenaria verna L. var. Gerardi Hook. fil. The Lizard, 
West Cornwall, June 21, 1913. — C. C. Vigurs. Comm. F . 
Rilstone. Of the Lizard specimens from a gathering by 
F. Jose dated 1905, Mr. Fraser writes : — The lower leaves 
are adpressed to the stem, and that is the strongest feature 
of the var. Gerardi. 
Sagina maritima G. Don. On shingle by W r est Looe River, 
E. Cornwall, July 1929.— F. Rilstone. Yes, good average 
specimens of the type. — C. E. Salmon. This belongs to the 
group in which the central stem, as well as the lateral branches 
bloom. I agree with the name. — J. Fraser. 
Spergularia marginata Kittel var. glandulosa Druce. Salt 
marsh, mouth of R. Brue, Somerset, v.c. 6, July 13, 1929. 
Seeds winged ; larger, more robust plants with longer leaves 
than S. salina, which is usually more stocky. — H. S. Thompson. 
An unusually lax form of the variety. Vide Joum. Bot. lix, 
p. 130 (1921). — H. W. Pugslev. 
Claytonia alsinoides Sims. Naturalised in a plantation 
near Petersfield, Hants., v.c. 12, May 20, 1929. — Ida M. 
Roper. I agree. It has the habit of C. sibirica L., but the 
two cauline leaves are much longer, more rhomboid and 
often shortly acuminate ; whereas the pair of cauline leaves 
of C. sibirica are suborbicular, and shortly cuspidate. Some 
authorities make the two specifically the same ; Dr. Druce 
makes C. alsinoides a variety of the other. They come from 
N. America, and C. sibirica from Northern Asia also. — 
J. Fraser. 
Hypericum undulatum Schousb. Carnkief, Perranzabuloe, 
W. Cornwall, Aug., 1928. — F. Rilstone. Very acceptable. — 
E. C. Wallace. This Western plant, so very rare on the 
Continent and in Britain, though frequent enough in Cornwall 
and about Plymouth, was not recorded as British until 
Archer Briggs published it in Journ. Bot., 1864, p. 45, and in 
Ed. III. of Eng. Botany about the same time. The figure is 
unsatisfactory. So is that in a paper by Babington in Journ. 
Bot., 1864, p. 97. When a young botanist, Briggs mistook it 
for dubium, and recorded it under that name in The Phytolo- 
gist, 1861, p. 369. But Cunnack of Helston “ lost the chance 
of being the first recorder of it as a native in Britain ” because 
a correspondent told him it was H. perforatum. The earliest 
specimens gathered by myself came from “ Boggy ground 
near Truro, July, 1886.” — H. S. Thompson.
