. A study of diversity in Egyptian cotton. different plants to show range of differencein shape and markings. The bracts show the typical Egyptian form withthe three middle teeth somewhat abruptly prominent. The calyx of theboll with the bracts is split and is not to be confused with the lobes of thecalyx of the hybrid shown in the next plate. (Natural size.) Plate V. Mature unopened bolls of first generation hybrid of Egyptian andUpland cottons at Yuma. The larger size, more pyramidal shape, smallerand more shallow pits, and pea-green color afford ready distinctions. (Nat-ural size.) Plate VI
