BRISTOL BOTANY IN 1915 AND 1916. 190 
Sisymbrium officinale Scop. var. leiocarpum DC. Until lately 
known only with us as a rare casual on waste ground. But the 
two forms have been found growing together in quantity by a 
grassy track on Ivory Hill, G., where it was evident that the 
variety could be recognised at once by its paler and greener 
tint, the type being somewhat hoary and becoming purplish- 
brown at length. 
Cerastium arvense L. Abundant in a rough, rocky pasture 
on the hillside near Axbridge, S. Discovered by Mr. H. S. 
Thompson. And Mrs. Reginald Price reports it from three spots 
on Lansdown, not far from the Grenville Monument. In this 
locality also the plant grows in natural turf. 
Spergularia rubra Pers. Detected by Mr. Cedric Bucknall 
on a dry pennant bank near the G.W.R. north of Keynsham. 
New to North Somerset. 
Medicago minima Iy. Sparingly casual at Newton St. L,oe, 
S., Miss Roper. 
Agrimonia odorata Mill. New to the Bristol district. This 
handsome plant has come out of its obscurity with a rush. In 
Journ. Bot. UII., p. 280, Mr. H. S. Thompson reports having 
met with it in three different places in North Somerset. First, 
in company with the Rev. E. Ellman, near Charterhouse, on 
Mendip. Shortly afterwards Mr. Thompson came across a 
larger quantity on the edge of a field near Blackdown. Then, 
a little later, he found three clumps near Farrington Gurney. 
And Miss Roper has it from the Court Hill above Norton's Wood, 
Clevedon. For failure to recognise this plant earlier the only 
valid excuse lies, I take it, in the scanty descriptions in English 
books. 
Potentilla argentea L. Discovered by the Rev. E. Ellman 
on a rocky limestone slope under the Cadbury ridge towards 
Clevedon. Extremely rare in Somerset. 
Rubus incurvaius Bab. A new bramble. Gathered near 
Edington Junction, S., in the summer of 1914, by Mr. E. 
Metcalfe Day, of Minchinhampton, and named by the Rev. W. 
Moyle Rogers. 
Dipsacus pilosus L. A number of fine specimens have 
appeared along a hedgerow near Clapton-in-Gordano, in a con- 
spicuous position, where it had never before been noticed by the 
Misses Cundall who live in the neighbourhood. 
Carthamus tinctorius L. Several plants on house-refuse 
tipped on the confines of Horfield, G., Mr. Ivor W. Evans. 
A handsome orange-flowered Composite, probably a native of 
Egypt and Abyssinia, and cultivated in many parts of the world 
for the colouring matter yielded by the flowers. According to 
old chroniclers this plant was formerly grown in Gloucester- 
shire, both for the flowers and seed. The common people used
