making the plant, which is said to be identical with the Teesdale 
form, a var. alpina. I cannot agree with Mr. N. E. Brown in 
‘ E. B. Suppl.,’ p. 35, in saying that P. austriaca^ Crantz, and 
P. amara, L., are identical, and his making amarella identical with 
calcarea is certainly wrong. — G. Claridge Druce. 
P. amarella^ Crantz. This species, which grows on the Great 
Scar Limestone in the West Riding of Yorkshire, was to be seen 
the past season in great abundance over a large area. It could be 
found in many situations and at various altitudes from Sweet Side, 
Grassington, to Buckden Pike, a distance of about nine miles as the 
crow flies ; from Buckden Pike to Arnclift’e, four and a half miles ; 
from Arncliffe to Gordale, five and a half miles ; and from Gordale 
through Bordley to Skythorne, four miles. These districts embrace 
an area, as measured on the Ordnance Map, of about thirty-six square 
miles. Specimens seen were from three to eight inches high at an 
elevation of 750 feet; as the elevation increased, the height 
diminished, till the plant became less than one inch high. Blue- 
flowered specimens were found well distributed over the whole area ; 
white-flowered specimens were unequally distributed ; rose-coloured 
plants were only found in one locality, but there it was locally abun- 
dant. Spathulate rosettes of root-leaves are the winter state of the 
plant. One characteristic of Polygala amarella is, that it can grow 
where there is but little soil for its support. I have found it growing 
on what was almost bare rock*; it has the habit of thrusting its roots 
into the cracks and crevices of rocks or between the stones and 
rocky fragments. Wherever I have found it, with one exception, 
there has been little or no depth of soil. — John Cryer. This is, 
no doubt, what Chodat has called P. amarella, Crantz. I do not 
know whether he distinguishes it from P. Amara, L., to which, indeed, 
our P. calcarea has sometimes been referred. It seems a good deal 
different from the Kent and Surrey P. austriaca. — E. S. Marshall.

D. gallicus, Pers. On the sand dunes St. Ouens Bay, Locus 
classicus, Jersey. Limited to a small area over which it is plentiful, 
the stiff tap-roots of the plants penetrating the soil to a considerable 
depth. Just coming into flower June 1906. It is difficult to under- 
stand that this plant with its beautiful and conspicuous blossoms 
should have remained unnoticed, if really indigenous there. I think 
it must be a comparatively recent introduction, although now per- 
fectly established. — G. Claridge Druce.
