In G the first conjugate division is just completed. (Adapted from Grove, British Rust Fungi.) as soon as it is formed, cuts off by conjugate division a small cell below, called the intercalary cell; this soon disorganizes and disappears, while the other portion remains as the aeciospore. The succeeding uredinio- spores have two nuclei in the conjugate condition and this is continued over into the cells of the young teliospores (Figs. 67 and 68). Before.
