56 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 

 stricta 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 hiimilis, Hypochceris glabra, Filago 

 minima, Lepturus filifonnis, Desmazeria loliacea, Phleum 

 arenarium, and Juncus 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. 

 SUene 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. XL, No. 1, 1912), and are 

 distinguished by the overlapping or divergence of the petal 

 lobes (/. incHinbens, f. diver gens), by their rolled margins 

 (/, involnta), the presence of lateral lobelets (/, lobata), the 

 abortion of the androecium (f.foemina), 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
