VEGETATION OF BLAKENEY POINT. 
p. 170). The plant has also been found in Suffolk, and 
has recently been recorded by the Rev. Riddelsdell from 
Glamorganshire. Two Sea Lavenders, viz., Statice binervosa 
and S. reticulata, which are also essentially Mediterranean, 
here approach their northern limit, though the former species 
extends its distribution into Lincolnshire, and on the west coast 
as far north as Wigton (Cumberland). 
Here, too, we find both Frankenia Icevis and Spartina 
strict a at the edge of their distribution ; the latter is not strictly 
in the area dealt with above, but is found in the Blakeney 
channel adjacent to the reclaimed salt marshes on the opposite 
side of the estuary. 
A number of other species met with, though of less distribu- 
tional interest, are of infrequent occurrence in the county. Of 
these the chief are Statice humilis, Hypoclueris glabra, Filago 
minima, Lepturus filiformis, Desmazeria loliacea, Phleurn 
arenarium, and J uncus maritimus. 
As we have already seen, the genus Statice is well repre- 
sented, and the same may be said of two other genera, viz., 
Triticum and Cochlearia. Of the former, not only do we find 
the two common maritime species, T. junceum and T . pungens, 
but also T. pungens var. aristatum , and more than one type 
of hybrid. Of the genus Cochlearia there are three species, 
viz., Cochlearia anglica, C. danica, and C. officinalis. 
Silene maritima is of considerable interest floristically, as 
it is here found under such numerous forms, which chiefly 
depend on floral characters and appear to be constant on 
any one plant. Most of these have already been described by 
the writer (New Phytologist, Vol. XI., No. 1, 1912), and are 
distinguished by the overlapping or divergence of the petal 
lobes {f. incumbens, f. divergens), by their rolled margins 
(/. involuta), the presence of lateral lobelets (/. lobata), the 
abortion of the androecium (/. fcemina), or the double character 
of the flowers. Besides these there is a marked difference in 
the coloration of the calyx, which may exhibit a more or less 
pronounced purple tint (the usual condition), whilst on other 
plants, the foliage of which is as a whole of a much lighter
