area near а clump of small poplar trees. Near the upper end 
of this area the plants differed in having smaller flowers (petals 
21 mm.) and narrow leaves (20 mm. broad). Тһе remainder of 
the plants had somewhat larger flowers (petals usually 25-27 
mm. long), and broader leaves (extreme width 50 mm.).! This 
was almost the only variation observed, and the race comes very 
close to the type of Œ. biennis L. The dimensions of the buds 
were as follows: bud cone 20 mm., hypanthium 25 mm., ovary 
11 mm., anthers surrounding the stigma. The rosette-leaves and 
stem-leaves all have red midribs both dorsally and ventrally. On 
the same stem some leaves are smooth and some more or less 
crinkled. The buds are green, devoid of red, with some long 
hairs, and there are no red рарШ on any part of the plant. 
Some of the larger plants are well-branched and with very stout 
stems, a huge pith and a very narrow ring of wood. 
This colony is even more uniform than the previous one, 
and must have originated from one or a very few plants. 
Small colonies of (E. biennis were seen at Formby, near the 
station and in other places. А race of Œ. Lamarckiana also 
grows here on the dunes, although I did not succeed in finding 
the spot, but local gardens cultivate it. The species is depicted, 
however, in a rose window erected in St. Luke’s Church, Formby, 
in 1898, containing representative plants of the local flora. 
The central portion of the window is divided hexagonally and in 
the six sections the evening primrose alternates with the sea 
holly. The foliage and large flowers of the former are distinctly 
shown. Around the margin of the window are Pyrola rotundi- 
folia and irises. 
At Blundell Sands, near Crosby, a small colony of Œ. Lamarck- 
jana was seen on waste ground, and again on the extensive 
sand dunes between Birkdale and Ainsdale, near Southport. 
In the latter case there were only three plants, and these pos- 
sessed red sepals, color pattern 7, green midribs, crinkled leaves, 
and about 2 long hairs. 
By far the greatest abundance of plants was found at St.
