This contains the free and superior gynaeceum formed of an ovary surrounded by a circular or obscurely crenulate disk, and sur- mounted by a style whose summit is dilated to a large stigmatiferous mass with five lobes separated by radiating grooves. In the internal angle of each ovarian cell, superposed to a petal, are found numerous anatropal descendent ^ ovules, arranged in two vertical series. The fruit is a nearly ovoid ^ septicidal capsule, whose five bilaminate valves are separated above and below by a thick columella, dilated below into five short wings, and loaded with numerous seeds, imbri- ' A douhle coat. 2 Slightly compressed in one Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Baillon, Henri Ernest, 1827-1895; Hartog, Marcus Manuel, 1851-.
