A small amount of white endosperm does not unfavorably affect popping, but if the white portion is in excess, as in flint maize, the corneous portion explodes without everting the endospenn. The varieties of pop maize may be divided into two groups, rice and pearl, w^th the golden as a rather distinct t}'pe of the pearl. The rice pop has a very pointed grain at the top, with a tendency to have the grains imbricated instead of side by side and to have the ears cone-shaped. In the pearl pop the top of the grain is smooth and rounded; the grains are compactly arranged upon the cob and are very dense and lus* trous in appearance. The ears are cylin- drical. The plant of pop maize is said to vary with variet}^, climate and soil from eighteen inches to t^velve feet; the usual variation being from five to seven feet.

The ears vary from one to eight and a half inches; usually from four to six inches in length and from one to one and a half inches in diameter. Variations from eight to thirty rows are reported, with twelve to sixteen rows the most common. An ordinary weight is from three to four ounces per ear.
