This is a perennial, native of SwilTerland, and moft other parts of 
Europe j a tall, handfome Plant, of regular growth and fingularly 
pleafing appearance ; flowering in July and Auguft. The Stalk is a yard 
high ; tough and firm j very gloflv on the furface; naturally of a faint 
and fimple green, but fometimes of a (hilling blue, and fometimes of 
a fhining white j in either of which rtates it is very beautiful. It rifes 
fingle from the ground ; but fpreads into a large, though compact 
head ; its growth from the firft Flower being what we have called 
Proliferous, with a Foolrtalk, as in moft other of the Eryngos. The 
Leaves are as the Stalks in colour, pale green, blueifh or whitifh j and 
fo it is with the Flowers : they are fineft of all when blue. Thefe vari- 
ations in colour are very ftriking at firft fight ; but the Plant is per- 
fectly and entirely the fame in all. They have done idly who gave the 
feveral appearances names ; Eryngium planum viride, planum caeruleum j 
planum Album; for there is not the leaft difference elfe in the feveral 
Plants.
