Some varieties of sorghum seed, such as “ rice wheat,” have 
the property of popping like pop-corn; so also the seeds of 
Amarantus leucospermus Wats., and are thus used in Mexico.

The split kernel exhibits the chit, starchy matter, and a corn- 
fous matter enveloping. It cannot be confounded with any 
other species except the pop, from which it is distinguished by 
the larger kernei and inability to “ pop.”

I find no synonyms for our vernacular “flint corn.’ It is the 
Indian corn, in yellow, red and blue or blue-mixed varieties found 
by the Pilgrims as mentioned by Mouart and Higginson; the In- 
dian wheat, yellow, red and blue of Josselyn.. Cartier, 1535, 
found two varieties in or near the present Montreal, one called 
Offici, as big as small peas, and hence probably our Canada 
: Twelve-rowed; the other called carracony, as great and somewhat —

1588, in Virginia, under the name pagatour seems to describe a » 
flint corn. This species is probably the Mays minor, with yellow, 
red and blue colors, which ripens in England in four months, as 
Fecorded in Miller’s dictionary, editions of 1731, 1748 and 1752; 
the Zea vulgare, caule humiliore, etc., of the edition of 1771, the 
“ats 4 to 5 inches long, the kernels yellowish white, deep yellow, 
Purple, blue and mixed, ripening in England. The Mandan In-  ~ 
dian Corn, as described by Salisbury, seems to be a flint,and a 
flint corn under the name of Mandan has come to me from Fort —
