Not illustrated. 1897 Excerpt: ...this case the nucleus is straight, but is inverted upon the funiculus, so that the micropyle is brought down into close proximity with the stalk, whilst the hilum and chalaza are separated, being united by a prolongation of the funiculus known as the raphe. This form is well seen in the Dandelion and Water-lily. Campylotropous or bent ovule (fig. 168, c). In this case the nucleus-is bent, so that whilst the micropyle is brought near FiG. 168.--Diagrammatic longitudinal sections of ovules: A, orthotropous or straight; 11, anatropous or inverted; and C, campylotropous or bent ovule, ai. Outer integument or primine; iV, inner integument or secundine; m, the micropyle; k, the nucleus, with the embryo-sac, em; c, the chalaza or base of the nucleus; _f, the funiculus; r, the raphe of the anatropal ovule, formed by the fusion of the outer integument and funiculus. (After Prantl.) the funiculus, as in the anatropous form, the chalaza and hilum are in close proximity as in the orthotropous form, and there is no need of a raphe. The Wallflower and Mallow are examples of this kind. These three forms are united by many modifications. Thalamus and Disc.--The thalamus, or end of the flowerstalk upon which the various floral organs are inserted, is often specially modified. Thus in all plants with a free central placentation it is prolonged into the ovary, bearing the ovules. In other cases, as in the Umbelliferae and Geraniaceae, it is prolonged between the carpels and beyond the ovary, and is known as the carpophore (see p. 149). In other cases, as in the Pink, Passion-flower, and Capparidaceae, it is prolonged beyond the calyx, forming a stalk for the ovary (figs. 169, 170), and it is known as the gynophore. In many plants it is much swollen, and the ovaries are sunk o...
