TUBER OF THE EDIBLE CANNA. 
(Carina edulis Ker. See S. P. I. No. 46313.) 
This tuber, with its brilliant white skin and crimson tip, is one of the most surprising things 
to dig up. It is almost as attractive and striking in appearance as a peach. Cooked, 
it is a palatable vegetable, somewhat resembling the turnip. As a producer of arrow- 
root, it has been cultivated for many years in Australia, where its heavy yields and ease 
of cultivation have made it more profitable than the Bermuda arrowroot (Maranta 
arundinacea) . Tuber grown from seed planted July 17, 1918, at the Plant Introduc- 
tion Field Station, Brooksville, Fla.; (photographed by David Fairchild, November 19, 
1918; P24620FS. Natural size.)
