authority cannot be given ('Gard. Chron. and Agricult. Gazette,' 1862, p.

degenerated by cultivation, so as to convey the change to the succeeding
crop."

Mais,' 1836, Pl. v. bis, and in the 'Journal of Hort. Soc.,' vol. i., 1846,
p. 115, where an account is given of the result of sowing the seed. A young
Guarany Indian, on seeing this kind of maize, told Auguste St. Hilaire
_(see_ De Candolle, 'Geograph. Bot.,' p. 951) that it grew wild in the
humid forests of his native land. Mr. Teschemacher, in 'Proc. Boston Soc.
Nat. Hist.,' Oct. 19th, 1842, gives an account of sowing the seed.
