 and (3) several culms of P. maritima and a label marked, not in 

 Nuttall's hand, "'P. [oa] maritima? sea-coast N. Jersey k Delaware'

The name Pucdnellia 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. Out 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.
