Genus Statice as represented at Blakeney Point. /. 
slightly more than in the typical narrow-leaved plant, the number of 
glands is slightly greater ; compare, for example, the plants from the 
muddy and sandy lows, and the culture plants, with the type form. 
Those plants which have been removed from their original home on the 
lateral shingle bank and have been for a year in cultivation under dis- 
tinctly more favourable conditions for root absorption show a smaller number 
of glands per unit area than in the case of the typical form — a condition 
to be expected, since any increase in the size of the leaf originally laid 
down would merely tend to spread out the glands, and would not lead 
to the development of new glandular structures in a leaf already developed. 
The same explanation possibly accounts for the difference between the 
gland counts in the case of the tall form from the Main bank and the 
type dwarf form from the lateral bank. 
Finally, it is interesting to note that though the number of glands per 
unit area in the case of the broad-leaved S. binervosa is intermediate, for 
the upper surface of the leaf, between that of its possible parent forms, no 
such relation obtains for the lower surface. 
Statice binervosa. 
i. The Seedling. 
The seeds of 5 . binervosa are probably often distributed by very 
high tides, and seedlings obtained from Blakeney in 1913 1 were found 
growing in mud among a tangled mass of Rhizoclonium filaments. Since 
seedling plants are not very commonly met with the species may be a 
‘ shy seeder ’, or else it is only when an exceptionally high tide occurs 
at the season for seed dispersal that seeds are scattered high enough up 
on the flanks of the laterals for a safe and stable place of germination 
to be obtained. This is the more probable in consideration of the facts 
stated with regard to the spread of binervosa near the Pelvetia marsh. 2 
The seedlings would appear to grow with extreme slowness, for seedlings 
collected in August, 1913, showed comparatively little advance on those 
collected in April of the same year. 
The seedlings of S. binervosa may be found in considerable numbers 
amongst the pebbles in the binervosa zone during March. Each possesses 
a pair of narrow, entire, and slightly spathulate cotyledons (Text-fig. 8), with 
very blunt apices about 4 to 5 mm. in length and from 1 to 1*5 mm. 
broad in the widest part. In colour the cotyledons are sometimes green, 
but are more usually of a deep crimson or port-wine colour, which is often 
shared by the first formed leaves. There is no external indication of a 
midrib. The cotyledons fuse at the base to form a very short tube. 
1 1913 seemed to be an exceptionally good year for seedling binervosa.
