Abstract

A typical anther is tetrasporangiate with two microsporangia in each lobe (see Bhandari 1984). When transverse septa develop in each microsporangium (Sect. 18.6), it becomes polysporangiate, as in the Annonaceae. In the Onagraceae (Tobe and Raven 1986a, b), transverse as well as longitudinal septa develop in each microsporangium (Sect. 39.13). At dehiscence, the septa break down in each lobe and the mature anther becomes bilocular (see Engler 1876). In Ficus ottoniifolia (Verkerke 1986a), each of the four sporangia dehisces independently (Sect. 10.4).
