Special importance is attached to the relative positionsof the perianth-whorls and stamens in relation to the pistil,or to their insertion ; the ovary [the lower part of the pistil]being inferior or superior in relation to the superior orinferior calyx, corolla, and stamens. Thus the ovary is ^ In all the diagrams, the Calyx is shaded a lighter colour than thecorolla. The External Form
