Botany. 94 OEGANOGEAPHY AND GLOSSOLOGY. of Euphorbia (fig. 333) consists of one whorl, reduced to one stamen ; and the female flower (fig. 406) of one whorl of three carpels ; the flowers of Arum (figs. 196, 197, 198) consist of a solitary stamen or carpel. Seeds, like the floral whorls, are subject to suppression and arrest; in Geranium (fig, 474) the five carpels are two-ovuled, and but single-seeded; the Oak (fig. 400) has three carpels forming three two-ovuled cells; the septa become speedily absorbed through the rapid growth of one of the ovules, and the ripe fruit is one-celled and one-seeded. presents a similar arrest. In the Cornflower and other Compositw, in Wheat and other Oramineae, the ovule is solitary from the first; at least, a second has never been discovered; thus offering a case of suppres- sion and not arrest. The causes which disguise or disturb symmetry in any one flower are not always isolated. In Larhspur we have unequal develop- ment and symphysis in the calyx and corolla, multiplication in the andrcBcium, and suppression in the pistil; in Asclepias (fig. 496) symphysis in all its whorls, multiplication in its corolla, dedu- Asciepias. pUcation in the second whorl of the corolla, and suppression in the pistil. Mignonette is an example of unequal development in its calyx, corolla and andrcecium; of symphysis in its pistil, of parallel deduplication in its coroUa, of collateral deduplication
