The name Puccinellia maritima has been applied to various plants 
in North America, but in its essential characters the coarse species, 
which abounds on the marshes from southern Maine to Rhode Island 
(and locally in Nova Scotia and formerly as a ballast plant at Phila- 
delphia), is the only American plant which closely matches the typical 
British material of P. maritima. Our plant is often taller and has 
larger panicles than the British material, in these characters approach- 
ing the large continental extreme which has been called Atropis 
Foucaudi Hackel. The American plant, however, varies so greatly 
in stature and in size of panicle and of spikelet that we have been 
unable satisfactorily to divide the material. The species appears to 
be undoubtedly indigenous on the coasts of Nova Scotia and New 
England, although sometimes also introduced on ballast; but south 
of New England it is apparently only a casual plant of ballast lands.
