136 Tlie Flora of Glamorgan. 



Occurs on all the muddy salt-marshes of our estuaries from the 

 Taff to the Loughor. It specially affects the steep muddy banks of 

 the small drainage channels which are so characteristic a feature of 

 most of our salt-marshes. 



Salicornia, Linn. 355. 



1 3 15. herbacea, Linn. Common Marsh Samphire. Llyrlys llysieuaidd. 

 Local. Abundant. Native. Littoral. 



Occurs on all the muddy salt-marshes of the county, and is very 

 variable. Four or five forms may be readily distinguished, and 

 Mr. Riddelsdell records the occurrence in the county of 5. appressa, 

 Dum., S. pusilla, Woods, S. stricta, Dum., S. procumbens, Sm., 

 S. ramosissima. Woods, and S. intermedia. Woods. The testing of 

 these various forms, by the method of " pedigree cultures," on 

 different soils, would probably lead to interesting results.
