CEREALS AND OTHER GRAINS 
Numbers 4367-4447 comprise various varieties and products 
of maize, or Indian corn, the grain of Zea Mays L. 
(Gramineae—Grass Family). Native of tropical Amer- 
ica and now cultivated in all tropical and warm- 
temperate regions. The group comprises four general 
divisions, each with various sub-divisions. 
A. Aboriginal forms. These are cultivated by primitive 
peoples in the native regions of the plant, and exhibit 
the smallest degree of development from the early, 
or original, form. They are largely used for parching. 
B. Field-corns. These are the coarser varieties, con- 
taining much starch and relatively little sugar, and 
used for grinding. 
C. Pop-corns. These have small ears and kernels and 
are used for popping. 
D. Sweet, or sugar, corns. These contain much sugar and 
relatively little starch, and the grain shrivels or 
wrinkles in drying. They are raised for use on the 
table, in the unripe state. 
As a rule, varieties of corn developed and grown in hot, 
moist countries have longer and narrower kernels and more 
rows upon the ear. The grain is softer, but has a stronger 
and tougher covering. 
Group A 
4367. A yellow, rather hard variety, grown in the South American Andes at high 
altitudes and mostly used for grinding. Acquired by R. S. Williams, in 
Bolivia, in 1902. 
4368. A soft white variety grown in the same region, and largely used for parching, 
in which condition it is the principal food carried by the natives on their 
journeys. Same source and donor. 
4369. Another soft white variety, used almost exclusively for parching. Same 
source and donor.
