Abstract
Two new mutations were found in the cultivated tetraploid cottons, Gossypium hirsutm L and G. barbadense L. One, annulated, causes rings of hypertrophied tissue to develop on stems and petioles of G. hirsutum. The character is inherited as a duplicated recessive and is assigned the symbols, an1, and an2 The second mutation alters leaf shape in G. barbadense and frequently eliminates the lateral lobes. Some distorted leaves are virtually oval in outline; hence the character is designated ovate. Ovate leaf is inherited as a duplicated recessive and is assigned the symbols, ov1, and ov2
