Sir William Hooker gives four forms of the Pteris aquilina, 

 namely, Glabra, Lanuginosa, Caudata, and Esculenta.

 in Northern Asia and North America. In the Highlands of 

 Scotland it is found two thousand feet above the sea level, 

 growing in sheltered situations to the height of six feet; whilst 

 on Helvelyn, at the same elevation, it scarcely attains as many 

 inches. Messina, Madeira, Cape of Good Hope, China, Java,
