Abstract
Ovule development, embryo sac formation, and embryogeny of I. Petraea
are described. The ovules are anatropous, unitegmic, and tenuinucellar. Meiosis in
the megaspore mother cell is regular and the chromosomes with terminalized chiasmata
form ring bivalents at metaphase 1. The Polygonum type embryo sac, Scutellaria type
endosperm development, and Solanad embryo formation correspond with development
patterns in other members of the Lobeliaceae.
