THE MAIUTIME FOHMS OF MATKICAKIA EKODOKA. 173 



plants which it is difficult to know whether to assign to var. salina 

 or var. maritima. But they do seem to represent recognizable types 

 round which the transitional forms may be grouped. 



Finally, attention may be called to Dr. L. M. Neuman's paper in 

 Botamska Notiser, 1882, pp. 167-175, in which he distinguishes 

 6 tonus (he does not call them varieties), the descriptions of which 

 are here reproduced. The synonyms given are Neuman's, with the 

 references verified and in some cases corrected.

2. Stems erect, leaf -divisions flattened.

Some of these forms probably occur on our northern coasts, and a 

 look-out should be kept for them. Further study is required before
