signing it a specific name. How far I acted wisely may be 
questioned. At any rate, as it has borne a name in British 
works for many years, it is right that it should now be figured, 
that persons visiting the western shores of Scotland may look 
out for it. Rigid and spiny as it looks, I have sometimes 
thought that it may be only an extravagant form of Pol. f- 
brillosa.
